Video Transcript for What to Know About the Replacement Race for 2788 Bearing

Today, we're going to review part number 2729. This is the Redline bearing race. This bearing race is designed to fit the inner bearing part number 2788. Basically, what this race does is this will actually be pressed or installed into the hub assembly. It would give a spot for the bearing to sit in. The rollers on the bearing will ride on this inside taper of the race.

This race does have a part number stamped on it, the 2729 right here. The most critical part of this is the outside diameter. When you need to order a race, you need to make sure that outside diameter is the correct diameter that will fit the bearing you have and fit in the hub on your trailer. It's measured in thousandths of an inch. I am actually going to use a digital caliper here and that will give us our readout.

The outside diameter on this race will be three inches. That should do it for our review on part number 2729.

Works fine!



by:

The hub bearings, seals, races and pads arrived and installed easy!



by:

Fits an M101A2 military trailer. Old bearings were slightly scored. Good insurance to replace them.



by:

Excellent company ! I got the bearings and races I needed to fix my military trailer perfect and at a very fair price



by:

Excellent follow up with customer service.
Items were exactly what I ordered.



by:

Still holding up after one year.



by:

The bearing and race replacements I ordered for my trailer have held up well a year later with 7K + miles on them.

I felt fortunate however that they were not damaged despite how they were shipped from etrailer. After all these are precision bearings and machined races.



by:

Exact product I needed at a great price. Terrific service



by:

Exact product ordered arrived as promised and at an unbeatable price.

Thank you

Disappointed in the packaging! 4 bearings, 4 races & 2 grease seals just thrown loosely into a envelope mailer! They just banged around for a week in the hands of the shipper! How can you just throw these kind of parts loose without individually wrapping them in bubble wrap? Horrible service!

Bearing looks great but I thought this ring on the left was a "race" do you have a replacement for that?

Thank you for your review. I believe you mean the grease seal. I have attached a link below:



by:

George,

I ended up at etrailer
after a fairly exhaustive search for all of the hard parts contained in my order. I found Timken bearings, but not all of them. I found SKF seals but they were 4 days out plus for delivery. The cost of USA made name brand bearings wasn't the issue for me, it was availability.

As you may know, the axle that takes those 3" OD inner bearings with such a small 1 1/2 spindle is an old, possibly very old Ag or boat trailer axle. They are meant for high load, but slow speed use. In comparison, the bearings you sent while appearing to be of good quality to the naked eye are also much smaller rollers indicating a higher speed bearing but of less maximum load capacity. None of this really matters when you have such a hard time finding the parts needed to complete the job in question. I simply state this for your information, but certainly, you were already aware if the differences in sizing and load capacity. It's doubtful that the trailer in question will EVER see enough load to make any difference in performance whatsoever, so please don't take my statement as a complaint.

As for the seals, they are the correct dimensions, and I did find your website helpful in double checking my cross reference work between brands. I'm also sure they will work just fine, but they do lack an innerspring to hold the tension of the inner lip seal against the spindle's seal area. Again, they will do the job, at least at first but I'd guess they won't last nearly as long and aren't a double lip seal design as the SKF, and National brands were. I'm not complaining one bit here, I promise. The cost factor differences were dramatic to say the least. The 2 inner bearings and 2 inner races made by Timken were equal to ALL 4 bearings and races, plus the seals from you guys.

Look, I realize that stocking such expensive and nearly obsolete parts made in the USA isn't a business model for anyone who wants to stay in business very long selling something that can be found down the street at nearly the same price. I understood what I was ordering before I ever started putting things into the cart on your website.

As a heavy equipment mechanic of 30 years experience, I promise your parts will get the best of treatment and a proper start to their life, hopefully, a long use life without issues. The bearings will be sonic cleaned before they are every packed with the best of grease choices. All the races and the seals will be installed with the proper driver to make sure they are square and seated correctly into the hub bore.

I assume if you use this review of mine for your website that you will not edit it in any way. What people using your site and customer service need to understand is that while I might see the differences I do not think I purchased ANY sub-par parts. Other customers need to also know that "In Stock" with you guys means "In Stock" and after hours of phone calls looking for those particular parts it was a very welcome thing to read on a website and even better when the order shipped On Time, Complete, and at what I consider to be a very reasonable cost. They would also need to know that your website is just chocked full of easy to find information. My example besides the seal cross reference information is the wiring diagrams. The color differences between RV trailers and Utility trailers makes you double check things to make sure you got it right and ALL that info is readily available on your site. Much easier to access than other companies.

In closing to what certainly is an overly detailed reply to your request for feedback, I'd just like to thank you, George. Thank you and your company for doing the EXACT thing you said you would and thank you for taking away a fair amount of frustration searching for parts. I will certainly use your company again and again if for nothing else, it's ease of use and promptness of service.

If you'd seriously like pictures I will be happy to try and supply them at a later date. For now, this old trailer has to get back to earning its way.

After some explaining to the owner of the trailer that none of these bearings were intended for high speed highway miles at least not many hes taken it easy on this ancient trailer. So far, everything works very well, with no grease leaking past seals and all the bearings carrying their weight well.



by:

etrailer had this hard to find bearing in stock. Delivery was as stated. My salesperson McCoy was helpful and knowledgeable. All the components were in one box ant individually wrapped, but fortunately no damage seen. Now the work putting everything back together begins.

Bearing and race were exact match. Good price and fast shipping!

No problems, everything is in good working order.

The serves you have given is out standing, couldn't any better.
I can only comment on one thing.. I was looking for the delivery by the (UPS)
as your Emails had suggested.. The items was sent by (USPS) this is no
problem. I thought UPS had screwed up like several weeks ago.
Now I don't have time to install them bearing right now as I'm cutting
fire wood, but as soon as I can get them installed I'll respond again.
Thanks George..
Best Regards..

Proper fit. Put them through 11 hours of use during the second day.



by:

great shipping, good price , bearing and race are going on a older axle and trailer that I am rebuilding



by:

Everything came as expected and on time. I was a bit surprised that, since the order was two angualar bearings, that the bearings weren't wrapped or protected from moisture in any way. In this case, it didn't seem to be an issue.



by:

Shipping was very fast and I am very satisfied with the product.
Bearings look of high-quality and all part numbers were a match to the old bearings,
I am a very satisfied customer and will be ordering all my bearings from this company

Perfect fit, great price.

  • How Can I Identify an Axle Without a Sticker?
    Thank you for the pictures! It looks like you've got some sort of square drop axle on your trailer and if you can't find an identifying sticker, I can still help you figure out what you've got so that you can make the swap to electric brakes on your trailer. It looks like you've got 6 bolts on the wheels, which can help narrow down our search, but we'll need to know what size the brakes on the trailer are and if possible, what size (or number) the inner and outer bearings are on the hubs.

    You can get a bearing with a 1-1/2 inch inner diameter here, and there are two options, with different outside diameters: - 1-1/2" Inner Diameter, 3" Outer Diameter: Replacement Trailer Hub Bearing # 2788 - 1-1/2" Inner Diameter, 2.563" Outer Diameter: Replacement Trailer Hub Bearing # 29749 If you need the races as well, the correct replacement race for # 29749 is the Race For 29749 Bearing # 29710; for the # 2788 it is the Replacement Race for 2788 Bearing # 2729.

  • Replacement Bearings, Races and Seals for Hub #22834
    Although the #22834 hub is an older, obsolete trailer hub, we do have the replacement parts you are looking for. From what I have found, this hub uses a # 29031 grease seal. The replacement inner bearing is # 2788 and the outer bearing is # 1779. The races you need are # 2729 and # 1729.

  • Finding a Hub for a Very Old Trailer with 6 Lug Bolt Pattern # 1779 inner and # 2788 Outer Bearings
    I did some research and found that the 2,600 lb Hub, # 22834, takes the # 1779 outer bearing and # 2788 inner bearing and would use the # 29031 grease seal. This hub has a 6 bolt on 5-1/2 inch bolt pattern. This sounds like the hub you have, and replacement parts are available. Along with the parts mentioned above you may need grease caps, # RG04-060, and races, # 1729 and # 2729, to complete parts needed to repair one of your existing hubs. When doing my research I found that no other...

  • Availability of Bearings 1779 and 2788
    We have the bearing part # 1779 and the race part # 1729. We also have the race part # 2729 and the bearing # 2788. Since I am not able to determine what seal you need based on your numbers I'd need you to get me the diameter of the spindle where the seal rides as well as the diameter of the hub where the seal installs.

  • Availability of Trailer Hub Using Timken # 2788 Inner Bearing and Timken # 1779 Outer Bearing
    I did find a reference to a trailer hub # 22834 that used a # 2788 inner and a # 1779 outer bearing, however I'm sorry to say the hub is obsolete and is no longer being manufactured. The hub has a 6 lug on 5-1/2 inch bolt circle. Although the hub isn't available, we do offer the bearings, the races # 1729 and # 2729 and the grease seal # 29031. If your hub(s) are damaged beyond repair, you'd need to replace the spindles or the entire axle. I can check on the availability of a replacement...

  • How to Find Replacement Hub for Trailer with Bower 2788 Bearing
    We do have the Replacement Trailer Hub Bearing # 2788 that installs on a hub using the Race # 2729, but the only hub we've confirmed a fitment with this on an older discontinued hub made for 5.2K axles with a 6 on 5-1/2" bolt pattern. Over the years hubs have mixed and matched bearings so the only way to make sure we get you the correct replacement parts is if you measure the different parts of your trailer spindle and let me know what you found.

    We do have the bearings, races, and a grease seal that seems to match. For the bearings and races you just need to enter the numbers you have given me and they will come up but they are not available in a kit. # 1779 (outer bearing) # 1729 (race for outer bearing) # 2788 (inner bearing) # 2729 (race for inner bearing) I did a cross reference check for a Victor Seal # 49739 and found that it is 1.875 inches inner diameter, 3 inches outer diameter, and is 7/16 inches thick.

  • Replacement Bearings 2788 and 1779
    Bearing # 2788 has an inner diameter of 1.50-inches and fits race # 2729. Bearing # 1779 has an inner diameter of 0.938-inches and fits race # 1729. We do offer all of these bearing and race parts and if you wish you can install new bearings in your current hubs. The idler hub you referenced, part # AKIHUB-655-6-K, uses different bearings that have different dimensions. The bearings in this hub are inner bearing # 25580 (1.75-inch inner diameter) and outer bearing # 15123 (1.25-inch inner...

  • What is the Axle Capacity for an Old Trailer with Hub # 22834
    The bearing numbers you have provided indicate that you have hub 22834. This hub is no longer made but there are parts for it such as the bearings # 2788 and # 1779 an the races # 2729 and # 1729. The hub is rated for 2,600 pounds which means it fits a 5,200 pound axle.

  • Replacement Parts for Oil Bath Hub with Seal 203034X and Bearing 1779
    That certainly does appear to be an oil bath hub. The seal number is associated with 1956 to 1959 Studebakers as far as I could find. It looks like the dimensions of the seal are 1.875 inches inner diameter and 3 inches outer diameter. We have one seal that has the dimensions, # 29031, but it is a grease seal, not an oil seal. The bearing # 1779 is associated with race # 1729. They fit hub 22834 which from what I could find is not an oil bath hub. The inner bearing that is associated with...

  • Replacement Bearings, Races and Grease Seals Old 6 Lug Utility Trailer Hubs
    I couldn't find that seal number for a cross-reference. Based on your manual caliper measurements the Grease Seal # 29031 is a perfect fit. Then you will use the bearing # 2788 and # 1779. If you need the replacement races for these then # 1729 and # 2729 are what you need. I recommend using the 7-Piece Installation Set for Bearings, Races, and Seals # PTW83020 to make removal of your current races and installing the new ones easier.

  • Replacement Brake Assembly, Bearings, Races, and Seal for Old Trailer Axle
    Based on the bolt pattern and the brake flange on your axle, you will want to start with the Electric Trailer Brake Kit - Self-Adjusting - 12" - Left and Right Hand Assemblies - 5.2K to 7K # AKEBRK-7-SA. Then for your hub drums I recommend reusing your current hubs as we don't have a suitable replacement and using bearings # 2788 and # 1779. Then for a seal I believe # 29031 is the correct fit. If you want to replace the races inside the hub use # 2729 and # 1729 along with the installation...

  • To Pick Out Trailer Hub Bearings Does the Hub Have to Be Totally Disassembled
    I know it's not the news you want to hear, but the only safe recommendation I can make for you would be to find a place you can park your trailer, pull the hubs and get the seals and bearing numbers so we can get you the right parts. I know it's a pain and it leaves you with a trailer stuck on jackstands till you get the right parts but it's the only option. Hexagonal caps that are threaded are typically used on oil bath hubs. I would recommend you at least inspect all the components...
