Dexter 7700063 / B55-29031
Lippert --
National/Timken --

How to Measure for a Replacement Seal


Measuring a spindle

Use a digital caliper and measure to the nearest thousandth of an inch.

  • Seal I.D.: Measure the diameter of the spindle at the grease seal seat (B), where the seal rides.
  • Seal O.D.: Remove the old seal and measure the inside diameter of the hub bore where the seal presses into the hub.

Measure each location in a few spots to check for wear or an out-of-round surface. Match both measurements to the replacement seal.

This size seal has been hard to find as it is on an older trailer with older axles. These were perfect and fit as expected and seemed to have a great seal on the axle. eTrailer again was great to work with as communications is the key thing they have always had. Thanks again and will be back again.

Excellent, couldnt be happier that their are good companies providing great services and good quality products Thank you again

Searched everywhere for these seals and these were exactly what I needed. Thanks!
by:
This seal did not fit my hub. The original seal was a National 203034 seal. The outside and inside diameter were the same but the rubber contact area was offset
by about 1/4 inch and would not grip my hub. The national seal was a centerline seal without any offset. If my seal area on my hub was longer then this seal would of have worked.

Thanks for the feedback Randy. But the National Seal cross reference for this seal is 440298. So that would likely be why this is not a direct match for you. I did look and at this time we do not carry a seal with this as a cross reference.

It was an really good fit. I sent you some pictures already,did you get them?

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!
by:
I had purchased a trailer with Trostel 300-156-6F seals and couldn't find anything at local stores for replacement. I took to the internet and found etrailer and the recommendation for these replacement seals. I ordered the seals, and they were quickly shipped and arrived at my house in a timely fashion. Replaced the old seals and worked perfect!
by:
These seals arrived on time and in good shape, although the package was torn open and I feared some kind of vandalism or theft. But both seals were contained in a small zip lock baggy inside the envelope. They are the correct size and just what I needed. Appreciate the speedy service and fair price. I will need two more next week and will place the order then. I wanted to sure these were the right size. They are. Thanks.

Exact replacement.

No problems, everything is in good working order.

by:
The young lady who helped me over the phone was outstanding. My old grease seal was by a manufacturer that was long, long gone. The part number did not translate into anything current. She helped me figure out which seal was most likely the right one for me. She was right on. Fit perfectly.
by:
etrailer had this hard to find part 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.
by:
Looks good, should work well.
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:
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..

Do you have a question about this Trailer Bearings Races Seals Cap?
  • Replacement Bearing for a Timken 1779 and 203034 Seal
    Hey George thanks for the information! We have the Timken 1779 it is the Replacement Trailer Hub Bearing item # 1779. The Timken 203034 seal has an outer diameter of 3" and an inner diameter of 1.875". The only seal we have which meets these dimensions is the Seal item # 29031. That is all I was able to find though. We do not have a bearing with a 1.5" inner diameter and we do not have any kind of bearing kits with the parts I was able to find. Do you know what kind of axle you have,...

  • Looking For Replacement Grease Seal For Older Utility Trailer
    Hello Travis, thanks for reaching out. We do have a grease seal that is very close to the dimensions you listed, although we don't have an exact match. Take a look at the following: - Grease Seal 29031 # 29031 This is 3" OD, 1.875" ID and 0.5" thick. A lot of older trailers use oddball/obsolete bearing and seal sizes, and it sounds like that might be the case here, but this seal will be the closest we have to what you need. If you're having a hard time finding a seal replacement it's...

  • Where Should Trailer Brake Assemblies be Grounded?
    Hey Larry, either way is going to work fine so whichever is easier for you will be fine. If it was me though I would ground the magnets to the frame near the axle just because that's simpler and requires less wire. It means less wire ran on the trailer which means less chance for something to get damaged etc.

  • Do You Have a 82" Wide Axle?
    Hey Charles. The closest axle I have to 82" wide is going to the 86-1/2" Dexter Trailer Axle Beam with E-Z Lube Spindles item # 8327816. This is a 5,200 lbs capacity axle but it's going to stick out an additional 2-1/4" on each side of your trailer. The spring seats are at 71-1/2". Did your current axle you're trying to replace come with the trailer and if so what brand of trailer is it?

  • Replacement Brake Assemblies and Hubs for 1960 Airstream Trailer
    It sounds like your assemblies are not the typical assemblies and will need to be replaced. For your brake assemblies, I recommend the Electric Trailer Brake Kit - Self-Adjusting # AKEBRK-7-SA along with mounting hardware # BRKH12. If you don't have the brake flange compatible, you can use the Brake Mounting Flange for 3" Round Axle # 4-44-1 which needs to be precisely welded in place. Then for your drum brake assemblies to match, I need some more information. I will need either the...

  • 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.

  • Replacement Seal For National Grease Seal # 5970
    Based on what I can find it shows the National seal 5970 is the same as the Timken 203034 which I see has an outer diameter of 3" and an inner diameter of 1.875". The only seal we have which meets these dimensions is the Seal # 29031. You can verify this will match your seal off of the measurements as I could not find a single resource which specifically showed the dimensions for the National 5970 seal.

    If the inner diameter is 1.719 inches and the outer diameter is 2.565 the # RG06-050 would be the closest matching grease seal we offer. You will need a digital or dial caliper for this measurement. The grease seal number you referenced doesn't cross reference with anything we offer but based on the bearing numbers a different customer came to us with that said they also had the same seal number you would need the # RG06-050. You would still need to measure to verify this. Also, if...

We do not have a ring available by itself for this seal but the seal should fit the spindles on your trailer perfectly without one. Just to make sure you can also measure the spindle where the grease seal rides with a digital caliper. If you get a measurement of...

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.

  • Old Trailer has 2 Different Sized Spindles and Obsolete Bearing and Seal Numbers
    That looks like a mobile home axle. It is possible that both axles are mobile home axles. But the problem with that is they are meant for one time use only. People get them because after they are used they are cheap. It is possible that this is also why the axles have two different sets of bearings. It is also extremely difficult to find parts for mobile home axles. The 2788 and 1779 bearings are associated with hub 22834 which is not available. The seal sounds like a # 29031 which has...

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.

To be sure, you can check the measurements of your seal. The measurements will have to be as accurate as possible so I recommend using a set of dial calipers. The inner diameter of the TruRyde seal is 1.719 inches. The outer diameter is 2.565 inches.
