These arrived faster than I could have expected. Quality looks good. They fit the UFP oil bath hubs on my Ranger Trail just fine. I had tried the name brand parts suppliers and a couple of trailer specialists in Jax, Fl. and they all thought I didn't know what I was talking about. One place could have ordered seals for $10.00 each. Thanks Etrailer. I have already recommended you to a friend. 116122


I sold that boat and trailer last fall. No problems related to using your products. Ill go to you first on any future projects and recommend to friends.Thanks, Steve

I have only driven 100 miles so my review doesn't carry much weight. If given opportunity later I will update. I will say I had confusing and sometimes unpleasant ordering experience until I called and Tommy C. took charge of my dilema as to go with bearing buddy seal kit or a double lip seal. I went with double lip as per Tommy suggestion. 133048


Good, much better than single lip seal. No grease leaking. You have to get double lip seals in my experience for boat trailer

These bearing seals install and work great! They were definitely oddballs--I couldn't find them anywhere else like Northern Tool, or Academy. In fact, twice, I bought the wrong set with the wrong advice from the store aids because they said, "It common, so it should work". Turns out, not so common after all. There's when I found etrailer...and glad I did! Thank you! 132083


Great! Boat Trailer glides like a champ with no leaks of grease or water in or out!

Want to help out the next customer looking for the bearing, cups, and seals for 2000-01 tracker trailstar trailer. 1st you have to dismantle one of the hubs and see what trailstar decided to put in there the day they built it. You will find the rear cups and seals are considered "Special for some reason". Not a problem for etrailer, they have them in stock and the quality is excellent and are exact replacements. The parts I had to order were cup L68110, cup L44610, seal 168233, bearing L68149 and bearing L44649. Oh yeah, customer service should get a 10 star review. I had an issue with shipping co. because of new driver in my area. Etrailer got all up in their business for me and I didn't have to do anything. Customer service also called me the next day to see if everything was delivered and satisfactory. We need more companys like etrailer.com . Excellent!! 207790

If you have UFP hubs on your boat trailer, these are the seals you need. Slightly smaller than standard 3500 lb axle hubs. As always etrailer was fast and provided great service. 110324


No issues after 1 year. Still holding up great!

Reliable and quick shipping, including tracking info., good prices. A great back-up company to deal with when our local parts companies can't fill the material requests.Seems like double lip, spring loaded seals are always tough to get. For marine applications they perform better. Highly recommend them. Great website, with good information and products. You know when you buy something from these folks, it's going to make it to the door. Thanks 60966

The bearing seals are now the right size and went in smoothly. I originally purchased the seals for Unique hubs as stated in your details. Unfortunately, these were EZ lube 3,500 seals and not the same as what I needed. I needed "Unique 84" seals which had a smaller diameter and ended up having to buy these in addition. I would recommend that you should improve your description as I'm sure others have had or will have, the same issue and those too will have to buy more than what they need. 140969

As always etrailer always has the hard to find parts I need. They are the only place I shop for trailer parts. Thanks to all employees, both who answer the phone and the tech's. Both are very courteous and helpful. The way an American company should be ran. Thanks etrailer! 149994

This seal was thinner than what I needed for my Cool Hub. I called and they were very helpful with the return process. I was very happy with the customer service. Overall a very good product though, I just messed up and got the wrong size. 178881

Was not able to find seal locally because shores could not cross reference the numbers. The etrailer web site did it for me and I received a seal that fit perfectly. Will not even shop locally in the future. Very good products and service. 146388

Just grease seals for a Zieman boat trailer. For some reason they were very hard to find and not locally available. To order them from a local parts store would have cost almost triple. Thank you!! 105379

Ask the Experts about this Redline Seals for Trailer Bearings
Do you have a question about this Seals for Trailer Bearing?

  • How to Measure to Determine the Correct Grease Seal for a Trailer Spindle
  • The # 168233 Double Lip Grease Seal has an outside diameter of 2.332 inches and an inside diameter of 1.688 inches. This seal is not compatible with a AF2527E seal with a O.D 2.312, because, even though the O.D. id very close, the inner diameter of the is seal is 1.750 inches and would not be the correct fit for the spindle diameter. You will need to take an accurate measurement of the outside diameter of your existing seal, or the inside diameter of the mounting surface for the seal...

  • Replacement Hub, Bearings, Races, and Seals for Trailer Hub with H-1377 Bearing
  • First, it does sound like, based on the measurement and information you have provided, that race # L68110, is correct since its outer diameter is 2.327 inches. This race is associated with bearing # L68149 which has an inner diameter of 1.378 inches and fits a number 84 spindle. On these spindles the diameter where the seal goes is 1.73 inches such as # R40484. The seal should be a tight fit. I once had a heck of a time pulling a hub off of a trailer that was held on by the seal only!...

  • What is Difference Between Bearing Seal NOK # AD2527E and # AD2527EO
  • We're not sure what the O stands for, in anything, but to make sure this bearing seal works for you you can take a few quick measurements. You will need to measure the outside diameter of your existing seal, or the inside diameter of the mounting surface for the seal in the hub. You will also need an accurate measurement of the spindle at the seal surface. I have posted a photo to show the dimensions you will need to measure. A dial caliper will provide an accurate measurement to determine...

  • Replacement Race # L68110 Availability and Compatibility with the # L68149 Bearing
  • The information I have indicates that the # L68149 bearing is compatible with a # L68110 race. The L68110 race is most commonly used in boat trailers and the # L68111 is most commonly used in land based trailers. They both take the same bearing, # L68149, but use different seals and the installation surface on the hubs are different dimensions, as you have noted. Most commonly the # L68110 race is associated with the # 168233 grease seal and the # L68111 race is most commonly associated...

  • Replacement Seal # 10-36 Recommendation for a Hub with Bearings 25580/LM67048
  • The correct grease seal that you would need is Grease Seals 10-36 pair, part # RG06-070. If you wanted a kit that had a replacement 25580 and 67048 bearings plus the 10-36 seal you would want a Bearing Kit, LM67048/25580 Bearings, 10-36 Seal, part # BK3-300. I attached a link to an FAQ article on wheel bearing backing as well as a video of how its done below for you to check out.

  • Which Grease Seal is Associated with L68149 Bearing and L68110 Race on a Boat Trailer Hub
  • When the L68149 bearing is paired with the L68111 race, the 10-19 grease seal is used. However when the same bearing is used with the L68110 race on a boat trailer, the # 168233 seal is usually used. You can verify this by using a digital caliper to measure the hub bore (inside diameter) where the seal would sit and the surface of the spindle where the inside diameter of the seal would ride. The hub bore should measure 2.332 inches and the surface of the spindle that the seal would...

  • Replacement Hub/Drum Assembly With 25580 Bearing for Use on Mobile Home Axle
  • Mobile home axles are designed for single-use, as when transporting the trailer to its permanent location. These often use uncommon bearings that are not readily available. In your case we do offer bearing # 25580 and we also offer hubs that use this part. The link provided will let you see all such hub/drum assemblies. You will need to know your outer bearing to match this as well. Filters on the page allow you to select that attribute, as well as the axle capacity, bolt pattern, drum...

  • Replacement Trailer Seal for a 2000 Trailstar Boat Trailer Measuring 2.327 Outer and 1.676 Inner
  • Given that we are talking about thousandths of an inch difference, it is very likely that grease seal, # 168233, is the correct seal for you. To be certain, you can find the inner and outer bearing numbers stamped into the metal of the bearings. That way I can determine all of the correct parts for your boat trailer. You can also look at the seal you have for a tiny, nearly unreadable part number on the black rubber part of the seal somewhere. It is very tough to read. But if you see...

  • Replacement Trailer Seal for a NOK 2527EO
  • The Grease Seal # 168233 that you referenced is listed in our cross reference chart as an exact replacement for the NOK AD2527EO. If the outer diameter and inner diameter match what your hub calls for they should work just fine. If the diameter of the portion of your spindle where the seal rides is right at 2.125 inches and the inner diameter of where the seal fits in the hub is 3.376 inches you would be just fine.

  • How to Measure to Get a Replacement Trailer Hub Grease Seal
  • The number 8752 that you referenced doesn't match up with any seal numbers that we carry, but there is a way to determine what replacement seal you would need. You will want to measure where the seal rides on your axle spindle with a dial or digital caliper to get an exact measurement and then you will want to measure the bore of the hub so that you know the inner and outer dimensions for a replacement seal. Check out the picture I attached for more info. Once you get those dimensions...

  • Replacement Bearings and Seals for Older Trailer
  • Thank you for providing the original bearing and seal numbers from your old trailer. These part reference numbers are often the best method for finding replacements, although especially with older trailers often alternate parts may have found their way into the trailer during its lifetime. We do have the bearings # LM67048 and # LM11949 as well as their matching races, parts # LM67010 and # LM11910. Please note that both of these bearings have an application as an OUTER bearing. The...

  • Will Grease Seal # 168233 Fit in Place of a Wider 0.41 Inch Thick Grease Seal
  • Double lip seal # 168233 should work just fine for you even though it is a little thinner than the seal you are looking for. If you could tell me what the inner and outer bearing numbers are I can determine if this is the best option or if there is something else that would work for you. But there are no other seals that have the same inner and outer diameter as this seal. Any time you pull a hub to pack bearings or replace anything inside the hub you are going to end up needing a new...
