Video Transcript for Review of etrailer Trailer Bearings Races Seals Caps - Bearings - 15123

Hello, everybody, this is Jeff at etrailer.com. Today, we take a look at this replacement 15123 trailer hub bearing. Now, this is a replacement tapered roller bearing. It's designed to fit to 5,200-pound, 6,000-pound and 7,000-pound axles. It is designed for high speed use and the bearing is always stamped with the industry standard part number. And if you look right here, you'll be able to see it, 15123.

Now, the bearing raise that this will sit in and operate, we do sell that separate on our website. That goes by a part number of 15245. And then the measurement on this, the important measurement is the inner diameter and on this one, it's 1.250. It is a stamped steel construction. Now, when this is installed on the spindle, it would need to be lubricated with either wheel bearing grease or oil.

But that's going to do it for a look at the replacement 15123 trailer hub bearing.

"Corroded/rusty grease seal I received was promptly replaced with a new one being sent to me. Thanks etrailer for the prompt response!"



by:

if you need it chances are e-trailer has is....... supper feast shipping and very helpful service. i service around 10 16' trailers at our shop and I have never needed something they didn't have, .



by:

All items were received in a timely manner, packaged decently and no damage upon receipt. I have yet to install however, hubs/rotors appear to be in pristine condition. Bearing and seals also appear to be top quality.



by:

i actually had two orders, one with Lori and one with Nicole. Both were very
helpful and i couldn't have had better service and assistance. I'm very pleased with everything. I have the parts installed completely and never took any pics.
shipping was very good also. if i need anything i'm sure to call etrailer. thanks john



by:

The trailer I'm rebuilding had obsolete bearings, but using a caliper I was able to find everything on etrailer. My local trailer supply place was ridiculously over priced so I went with etrailer. Thank You for the quick delivery.



by:

I have an older boat trailer and was able to find all the parts I needed to get it back on the road on etrailer.com



by:

My order shipped and was delivered faster than expected. The parts are top quality and the installation has gone smoothly. I am very pleased with the staff at e trailer as they were very helpful, courteous, and were genuinely concerned with my order. I definitely will order again from e trailer and will recommend them to my friends.

Thank you e trailer for your help.



by:

Had to return my first order. etrailer offers services for identification of bearings from numbers on the side of the bearing; type bearing used on type axle; weight class of the bearing; and "some" dimensions. None of the aforementioned were available to me and I matched the published dimensions. It was the missing dimension that was wrong and not published which led to the wrong order. All my orders with etrailer were right on except this one- tough situation for the supplier and the buyer, perhaps an area in need of improvement.



by:

I have a 10K dump trailer that I lent out, it was overloaded and bent an axle. Having never replaced one. I was grateful for the assistance getting the correct parts, including an axle, bolts, bearings, seals etc. The parts fit and assembled well. Nice going fellas, I'll be back.



by:

As always the shipping was quick and everything was packaged professionally. Parts went on with no problems. etrailer is my go to place for rv 5er parts. Also if you have a question just ask their experts and you will get a fast and accurate reply.



by:

I have used etrailer bearings and races for the last 10 years on our 5th Wheel trailer. The etrailer.com web site is easy to navigate and the ordering process is helpful and easy to navigate. All my etrailer orders arrive on schedule and the products arrive in perfect condition.

Based on my experience with etrailer I recommend ordering products from this company to all my friends that do their own work.



by:

It was great doing business-- Customer service helped me with some options on my order when the races needed in a kit were not in stock for another 2 weeks. Sent the rest of my parts rather than wait for the races, (found the races locally at 80% more cost ) but I am able to get my boat trailer on the road in time for our planned vacation. Their prices will save you money! I highly recommend them and will order in the future. One small con- As I read in other posts, It would be nice to see them individually wrap all bearings and races ( rust preventive or kraft paper perhaps?) to prevent nicks and scratches in shipment, but otherwise I am completely satisfied with their service and pricing!



by:

Product good, Shipping great, packaging for shipping very bad. I have worked with bearings for 40 years and have had several training's for timken, fag, and others.
never have i seen bearing just put in a box with no covering. bearing should be sealed and not allowed to spin freely until time of use. they are usually wrapped with some sort of covering or at a minimum boxed individually.



by:

I think the product is fine only time will tell but the process of ordering and the rapid delivery and Stacy we the best me trailers has it ad the price is good and as promised

Used these on a homemade flatbed reusing an old camper axle from the 50's the numbers on the old bearings did not cross to anything current, fortunately E Trailer has the specs online a few measurements with a caliper and you are in business. Thanks E Trailer



by:

Bought new axel parts and brakes bigger wheels for my boat trailer. My existing axel was 20 years old and never was adequate for the weight it hauled causing wheel bearings to wear out and the chance of loosing a wheel. This was the most economical way to repair as a new trailer was so expensive. All the parts I needed were available and went together beautifully. Very happy with etrailer, this is not the first time I have ordered from them great option for any parts you need.



by:

This was a perfect fit for my Lippert 6,000 lb. axle outer wheel bearing used on our 2006 Heartland Bighorn 3055 5th wheel.

So Far, So Good, Better bearings than original.



by:

Everything fit fine. I haven't put enough miles on them to give them an excellent rating.



by:

I received the shipment today, quick 3 day delivery. I was somewhat surprised to find each item loose in the box, definitely not how I have seen bearing when opening a box. Being shipped loose in a box does not prevent damage to some of the parts or prevent moisture damage (rust). For the parts I will not be using immediately, they will be packaged separately and coated in a film of oil or grease to prevent rust.

I added the bearings and endcaps to my spare parts inventory.



by:

These outer bearing took a couple weeks for delivery and when they arrived the were loose in a cheap unprotected plastic bags. That’s BS customer service in my view!!!!!

I ordered bearing before that came individually boxed for protecting the bearing for being banged around in shipping.

Very disappointing and pretty much done with etrailer.



by:

Fit perfect, fast delivery. Too bad the loaded brake hub I purchased was missing this bearing, so I had to order a replacement.



by:

Excellent product & price



by:

Great quality, great prices. I converted an old gooseneck trailer from the open center mobile home-style hubs to modern 6k hubs on a budget. These fit the replacement hub/brake units that I had. Was able to get all the missing pieces I needed from etrailer.



by:

everything fit as it should, making the replacement very easy.



by:

Joy was very helpful with making sure I ordered the correct parts for my camper I would recommend etrailer in the future

  • Pre-Greased Replacement 5-on-5 Hub for 3500-lb Dexter Axle
    You can confirm the weight rating of your Dexter axle by removing one hub and pulling its bearings. The included photo shows how part numbers usually appear on bearings. The specific bearings used will tell you the axle's weight rating. Just refer to the linked article that lists the bearings commonly used for various axle weight ratings. A new hub must use the same bearings as the original hub in order to fit on your spindles. A 3500-lb axle commonly uses bearings # L68149 and # L44649...

  • Can a Hub with Outer Bearing 15123 and LM67048 Both Fit Same Spindle
    The inner diameters of the LM67048 and 15123 both are the same (1.250 inches). That means that a hub with either bearing in the outer bearing would fit your spindle. The part # AKHD-655-6-EZ-K would fit your axle.

  • Replacement Bearing Kit For Dexter 6,000 lb Axle 2266389
    Hey David, thanks for the picture. I was able to track down a spec sheet for your Dexter axle which I have included below. The 031-029-02 bearing is item # 15123 and the 031-030-02 bearing is item # 25580. For a bearing kit you can use part # BK3-110 which will come with both bearings, races, grease seal, spindle washer and cotter pin.

  • Recommended 5 Spoke Hub For M1102 Military Trailer
    The Dexter Trailer Hub and Drum Assembly - 6,000-lb and 7,000-lb Axles - 12" - 5 Spoke Utility # 8-174-5UC3 is the only hub that is compatible with those bearing inner diameters. This uses # 15123 which have the same inner diameter as the # 14125A, it simply uses a different race so it will be compatible.

  • Electric Over Hydraulic Disc Brake Conversion For Boat Trailer With Two Dexter 6K Axles
    Hello Dustin, thanks for reaching out. We actually carry conversion kits that are made specifically for this purpose. For your boat trailer with 6K Dexter axles, you can use the Hydrastar Electric Over Hydraulic Actuator Kit for Disc Brakes # HBA16-252-82 which will come with everything you need minus the disc brake kit itself. For a disc brake kit I recommend the DeeMaxx Disc Brakes # DE58YR. This kit comes with stainless calipers and the rotors use a rust-resistant Maxx coat which is...

  • Replacement Hubs And Brake Assemblies For A 2006 Colorado 5th Wheel
    Hello David, I can definitely point you in the right direction. The Lippert 5,200 lb axles will use the standard 12" x 2" brake assemblies. For that I recommend the etrailer Rust-Resistant Electric Trailer Brakes # AKEBRK-7-D. This comes with a pair of Dacromet coasted electric brake assemblies. As far as the hubs, it is not quite so cut and dry. The 5,200 lb axles generally use a # 25580 inner bearing and a # 15123 outer bearing. Given that your axle is almost 20 years old, it may not...

  • Can A Hub With A 15123 Bearing Be used To Replace A Hub That Used An LM67048 Bearing?
    Hi Aaron! The # 15123 bearing included with the TruRyde Trailer Hub and Drum Assembly - 5,200-lb and 6,000-lb Axles - 12" - 6 on 5-1/2 - Pre-Greased # TRU38AV has the same 1.25" inner diameter as the # LM67048 bearing, so you can indeed use this hub. That said, make sure the inner bearing is either a # 25580 or has a 1.75" inner diameter and the seal is either a # GS-2250DL or has an inner diameter of 2.25" as well. These are what come with the # TRU38AV hub/drum. As long as all these...

You can add this information, along with any other questions you have, where it says Add Comment. The Dexter 4,400 lbs axles use the same hubs as 3,500 lbs axles, which have item # L68149 inner and item # L44649 outer bearings.

    We do offer the Replacement Trailer Hub Bearing, part # 15123 for your trailer but I was unable to find a cross-reference for the Timken 09067 bearing you stated you need. You can measure the inner diameter and see if there are any bearings from the attached pages that would work as a replacement for you. We also offer the matching race for the 15123 and that is part # 15245.

    Hey Steve, Thank you for that information you provided, it sets me up to get you the direct replacements.

This is the left and right hand assemblies that came originally on the trailer, ready to slide on and bolt on for you. We have the hub and drum assemblies as well that are pre greased with the bearings, races and seals already in them ready to slide on. For that you want to...

    Hi Kevin; do you have # 25580 inner and # 14125A outer bearings? Assuming you do, the Easy Grease Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K you looked at will fit. The outer bearing is a # 15123 which has the same 1.25" inner diameter so it will work with your spindle. This hub has a 6 on 5-1/2 bolt pattern and a 12" diameter x 2" wide drum.

  • Which Bearing And Seal Kit Is Needed For 2022 Cougar 368MBI Travel Trailer With Dexter 6K Axles?
    Hey there Mark! That's a great idea to stock up on some spare parts. Most people don't have the foresight like that. You will need either Bearing Kit, 15123/25580 Bearings, GS-2125DL Seal # BK3-110 or Bearing Kit, 15123/ 25580 Bearings, 10-36 Seal # BK3-100 depending on if you have the 2.125" or 2.250" inner diameter seal. You likely have the 2.250" I.D. seal but you'd need to check the part number or measure the seal to verify, unfortunately. The only difference in the kits is the grease...

  • Bearing And Seal Kit Needed For A Dexter D60 Axle
    Hey Brian, For inner bearing # 15123 you would need race # 15245 and for outer bearing # 25580 you would need race # 25520. The grease seal can be purchased with part # GS-2250DL. The Timken Bearing Kit # TMK42VR would include 15123/25580 Bearings, 15245/25520 Races, and 412920 Seal (2.25" ID/3.376" OD).

  • Disc Brake Kit for Load Rite 5 Starr Boat Trailer
    Hi Shayne; I wasn't able to find anything that corresponds with those tags or part numbers. However, based on the 12" rotor and the 6 on 5-1/2 bolt pattern the Kodiak Disc Brakes # KOD69FR you were looking at will likely fit. This is designed to for a #42 spindle on a 5,200 lb or 6,000 lb axle. What you can do is check your axle tag to see if it has a serial number or capacity to identify it. If not, you can look at your bearings to see if they match. The numbers will be stamped in the...

  • Timbren Axle-Less Suspension System Compatible with Jeep for Matching Trailer
    For the Timbren Axle-Less kit compatible with the bolt pattern of 5 on 5 like a Jeep, you would need the 2,200 lb capacity # ASR1THDS03. The spindles on the Timbren system are a little larger than their thru-axle counterparts, so the 3,500 lbs # ASR3500S06 will only fit larger hubs that won't have the bolt pattern you seek. Using # ASR1THDS03, you can then use the Trailer Idler Hub Assembly for 3,500-lb E-Z Lube Axles - 5 on 5 # AKIHUB-550-35-EZ-K or the Trailer Hub and Drum Assembly...

    Hi Jim! The Dexter Trailer Hub and Drum Assembly # 8-201-5UC3-EZ and # 8-201-9UC3-EZ are very similar, but there are a couple differences. You noted the weight capacity differences, and that is due to the bearing combination, which I have listed below: # 8-201-5UC3-EZ Inner bearing # 25580 (1.75" inner diameter) Outer bearing # LM67048 (1.25" inner diameter) Inner race # 25520 Outer race # LM67010 # 8-201-9UC3-EZ Inner bearing # 25580 (1.75" inner diameter) Outer bearing # 15123 (1.25"...

  • Do You Have a 6,000 lbs Axle w/ a 89" Hub Face?
    Hey Val. Our Trailer Axle Beam with Easy Grease Spindles item # e23GR is going to be the best option for a 6,000 lbs capacity axle that's 89" long. We don't have any axles with a 68.5" spring seat so you'll need to have a welder install two of the Spring Seats item # TRSS300 per axle to attach the axle to your suspension. The spindles fit item # 25580 inner and item # 15123 outer bearings. You'll also need a set of the U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles...

You need to take apart your old hub in order to find out if you have the same bearing numbers. If so hub and drum assembly # AKHD-550-35-K will work; for an idler hub assembly # AKIHUB-550-35-K would be the right choice. I've added a link to video reviews of these parts for you...

  • Replacement Trailer Brake Assemblies For a 2011 Forest River Sierra 5TH Wheel Camper
    I recommend the Dexter Nev-R-Adjust Electric Trailer Brake Kit # 23-458-459 for your 2011 Forest River Sierra 300RL. These will only require you to adjust the brakes to ensure they are set correctly when you install them. After that they will self adjust themselves as the brake material wears away. This will ensure your brakes last longer and will keep you out from under the trailer adjusting the brakes. The Trailer Hub and Drum Assembly # AKHD-655-6-EZ-K will provide you with a new hub/drum...

  • What Bearings do I Need for the Kodiak Disc Brake Kit with 12" Rotor ?
    Hello David, I am happy to see you finally found a reason to write into us after being a loyal etrailer neighbor (customer) since 2010! The Kodiak Disc Brake Kit - 12" Rotor - 6 on 5-1/2 - Dacromet and KodaGuard - 5,200 to 6,000 lbs # K2R526DKG uses a slip-on rotor, so you will also need an idler hub to complete the setup.

    Hey, Matthew! I just want to make sure I’m understanding you correctly, when you mention needing two different size outer bearings, can you tell me a bit more about what you mean? For a 6,000 lb hub with that bolt pattern, you’ll typically need: Inner bearing: # 25580 Outer bearing: # 15123 If you’re replacing the bearings, it’s a good idea to replace the seal as well, since they often get damaged when removing the hub. Your setup most likely uses seal # GS-2125DL. Let me know if you...

  • Determining Capacity of an Old Trailer Axle with No Information on the Axle
    The 15123 bearing is still common but I could not find any information on the 09057 bearing. But given that your hubs have the 4 bolt pattern it is likely that the axle is rated under 3,000 pounds. Most likely it is a 2,000 pound axle. Measure the spindle where the 09057 bearing rides using calipers such as # PTW80157 I can see if there is a different bearing with the same inner diameter that is commonly used with 15123 and go from there. Since you still have the trailer frame as well...
