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!"
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, .
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.
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
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.
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
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.
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.
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.
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.
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.
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!
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.
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
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.
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.
Everything fit fine. I haven't put enough miles on them to give them an excellent rating.
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.
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.
Fit perfect, fast delivery. Too bad the loaded brake hub I purchased was missing this bearing, so I had to order a replacement.
Excellent product & price
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.
everything fit as it should, making the replacement very easy.
Joy was very helpful with making sure I ordered the correct parts for my camper I would recommend etrailer in the future
