A unitized seal is a dual action seal. The inner part stays fixed on the spindle and the outer casing rotates with the hub. This type of seal has less wear and tear and provides better leak protection.

Unitized Oil Seal for Trailer Hubs - 10-63

Average Customer Rating:  4.9 out of 5 stars   (46 Customer Reviews)


by:

I just changed my hus on my 5th wheel from grease to oil bath from trailer. The kit do do so included these oil seal. As a after thought I wanted a backup set of seal just in case. I thought the price was alittle high but I didn't have time to explore the internet for a lower price so I ordered a set. I may never have to use them but I have peace of mind that they are onboard.



by:

I really like these seals, they cost more, but they do an excellent job of oil control, the only disadvantage is if you remove the hub, the seal is probably not going to be reusable, my ratio is about 50/50 but careful patient disassembly helps. I highly recommend this seal for hub rotors that are oil bath, not for drums that are grease and need removal to change brakes. I put about 80k miles on my trailer per year, very happy with the performance



by:

Installation was without issue and they are working like a champ!



by:

The cheap single lip oem seals all leaked grease onto the brake shoes, what a mess! These oil bath seals are well worth the money and do not leak.



by:

Need to ship in better packaging. Boxes came in with holes. Parts were missing.
Replacement parts were sent out but the job is now delayed waiting on the parts.



by:

Purchased these for spares after using the last spares redoing my bearings. I try to ALWAYS have a spare set on hand. Not exactly the same as the previous ones but will certainly do the job.



by:

Exactly what was needed. Installed fine. Outstanding customer service by etrailer.com. I was in a rush, needed the part overnight and my rep watched the order, told me when it shipped and followed it through until it was in my hands. Can't ask for anything more!!

Customer service ++



by:

I haven't had it long so can't speak of the longevity, the quality looks good and it figs perfect and works as we speak



by:

This seal is of better quality then any other seals I have had in the past, these should last a lifetime. This place has good prices on some hard to find parts, can get almost anything you need, reasonable shipping with lots of options.



by:

This oil seal is a one time use. If you remove it the internal spring pops out.



by:

Great to do business with. Always get what I need when I need it. Ricky at Etrailer is on top of my favorites list.

  • Will Grease Seal RG06-070 Replace the Dexter Seal K71-386-00
    Correct, although the TruRyde Seal part # RG06-070 has the same dimensions as the Dexter Seal part K71-386-00, the TruRyde is for grease and the Dexter is for oil. The Dexter Seal part K71-386-00 cross-references to our Unitized Oil Seal for Trailer Hubs part # 10-63.

  • 7,000 lb Hub and Rotor With Oil Bath
    The Dexter Trailer Hub and Drum Assembly - 5,200-lb to 7,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-219-9UC3-A should not be machined in order to be used as a hub and rotor, but there is an oil bath hub and rotor with the same bearings and seal as this drum assembly. The Dexter 12-1/4" Hub-and-Rotor Assembly - Oil - 8 on 6-1/2 - E-Coat - 9/16" Bolts - 7K # 008-416-93 uses inner bearing # 25580, outer bearing # 14125A, and Oil Seal # 10-63, which are the same as the drum assembly it sounds...

  • Replacement Hub Seal for Dexter 7k Trailer Axle
    The interesting thing about Dexter 7k axles is that they could come with two different grease seals with the only difference being the inner diameter of the seal. If the inner diameter is 2.25 inch you'd want the part # 10-63 or if it's 2.125 you'd want # 21325. Easiest way to take this measurement is to pull a hub and measure the spindle where the seal rides.

  • Can Dexter Hub & Drum 8-393-4UC3 be Used as Oil Bath Hub
    If you prefer an oil bath, you can do so with the Dexter Trailer Hub and Drum Assembly for 7,200-lb Axles Manufactured After 1999 # 8-393-4UC3. What you would need are the Unitized Oil Seal # 10-63 and Oil Cap, Plug and O-Ring for Dexter 7-9K Trailer Axles # RG04-230. Having said that, I recommend sticking with grease as opposed to oil. While oil can be less maintenance, they are both prone to leaks and don't keep water out of hubs as well as a grease cap. The issue with this is that...

  • Replacement Grease Seal For a Dexter Hub On a 2,200LB Trailer Axle
    The Grease Seal # 10-9 is the size used on a Dexter 2,200LB Hub Assembly # 8-258-50UC1-EZ. This seal has the same 1.5" ID but only a 1.987 OD. We do not have any seals with a 2.080" OD at this time or that are entirely rubber for an oil seal like the Unitized Oil Seal # 10-63 you found.

  • Replacement Hub and Drums For PJT Trailer With 008-393-03 Installed
    Thanks for all of the information on your PJT Trailer! Based on your drum part number you have a 12-1/4" Drum that is oil bath. The Dexter # 8-393-4UC3 is almost right, but it is designed for grease and not oil. You will need the # 8-393-4UC3 and oil seal # 10-63 for each hub. This hub does not include the bearings so you will also need new inner bearing # 25580 and outer bearing # 02475 for each hub. If you need replacement brakes now or in the future you will need # 23-428-429 for...

  • Correct Oil Seal for Dexter 10K 8-214-5UC1 Hub/9-27 Brake Drum
    The 9-27 (it's 9-27-1, actually) brake drum is part of a 2 piece hub/drum that uses # 8-214-5UC1 for the oil bath hub assembly. The correct oil seal is part # 10-56. The seal has an OD of 4.5 inches, and an ID of 3.125 inches. The # 10-63 you'd mentioned is too small, as its typically used with 8K capacity axles, so it wouldn't be compatible.

  • Recommended Way to Add Disc Brakes to 2020 Momentum 376THS
    The first thing you'd want is the Kodiak Disc Brake Kit # K2HR79E for each axle. This is a 7k kit with an oil bath dust cover that fits your current spindles and also is compatible with your wheel size. For bearings you'd need to order the # 25580 and # 02475 separately as well as the seal # 10-63 as they are not included. Since you have a triple axle trailer you'd need three of the disc brake kits and 6 each of the bearings and seals. For an actuator kit the best option is the Hydrastar...

  • Parts Needed To Change Trailer Hubs From Grease To Oil Bath
    In order to be able to change your hubs from using grease to an oil bath you need a couple items. For the hubs you said have an inner diameter of 2.44 I recommend the Kodiak XL ProLube Oil Bath Hub Body and Cap, part # XLPROLUBE2440. This has the hub body that fits in your hub and a cap with threads. You will also need the Unitized Oil Seal, part # 10-63 for your hubs. This is a dual action seal. The inner part of the seal stays fixed in place on the spindle and the outer part turns...

  • Comparing TruRyde 10-36 Grease and Dexter 10-63 Oil Seal
    The TruRyde Grease Seal part # RG06-070 and Dexter Oil Seal part # 10-63 are both designed for the same size spindle as they have the same dimensions, 2.250" inner diameter and 3.376" outer diameter. That said, the TruRyde is a grease seal therefore designed to be used with grease lubricated hubs. The Dexter is an oil seal which is designed to be used with oil bath lubricated hubs although can be used with grease as well because of the tighter fit.

  • Replacement Oil Seal Recommendation for Dexter Hub Part # 8-285-10UC3-A

  • Replacement Brake Assembly and Oil Seal for Dexter 00828510 Brake Drums
    It looks as if you have the # 8-285-10UC3-A Dexter Oil Bath hubs. Thanks for sending the photo! Those hubs take a 12 x 3-3/8 inch brake assembly, I'd recommend a self-adjusting brake assembly kit like # K23-532-533-00 which are compatible with a 4 bolt brake flange. This includes the right and left brake assembly. The correct oil seal for your hubs is # 10-63, which has a 2.25 inch ID and a 3.376 inch OD. You can see some product videos for these product by clicking the provided links.

  • Replacement Seal for National Seal or Timken Seal 472920
    National seal 472920 has an inner diameter of 2.25 inches and outer diameter of 3.375. For a replacement, you will want Grease Seal - Double Lip # GS-2250DL or oil seal # 10-63.

  • Removal and Installation of a Unitized Oil Seal for a Trailer Oil Bath Hub
    Unitized oil seals such as # 10-63 for example are different than regular grease seals. Unitized seals have an inner part that stays fixed to the spindle on the axle and its outer case rotates with the trailer hub. You would remove and reinstall a new one the same way you would with a regular seal. The best tool to use for unitized seals is a seal removal tool which you should be able to get at a local auto parts store. Once you pry out the old seal, place the new one in the hub. Use a...

  • Disc Brake Conversion For 2016 Grand Design GD Momentum With Lippert 7000 lb Triple Axle
    For your Lippert 7,000 lb axles on your 2016 Grand Design GD Momentum triple axle trailer, I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs # K2HR79E. These fit the industry standard number 42 spindles. For this you will need the inner bearing # 25580 and outer bearing # 02475 along with oil seal # 10-63. I recommend you check the bearing diameters to make sure they match your spindles. For your disc brakes you will need a different actuator capable...

  • Will Double Lip Grease Seal or Unitized Oil Seal do Better Job of Retaining Grease in Hubs
    The TruRyde Grease Seal # GS-2250DL referenced in your question is a double lip seal that will do a great job at retaining the grease inside your hubs. They will also exclude water and road grime better than a standard single lip seal. The Redline Unitized Oil Seal # 10-63 you also referenced will do a nice job at providing leak protection with the dual action seal as well. The inner part on the seal will stay fixed on the spindle while the outer casing rotates with the hub. I like this...

  • Unitized Oil Seal for Trailer Hubs Installation and Lowest Price Pledge
    The item you selected, while having the right measurements, is not a unitized oil seal. We do carry the 10-63 unitized oil seal (see link). Installing the seal requires pressing the seal flush or slightly into the hub. I normally use a wooden block to seat the seal flush with the back side of the hub. We have an install video for you to watch that shows installation of a grease seal. Normally flush installation is correct unless Tie Down Engineering specifies differently.

  • Can Oil Seal be Used in Place of Grease Seal
    So long as the dimensions are what you need, you can use an oil seal as opposed to a grease seal on your trailer hub. For example, the Oil Seal # 10-63 and Grease Seal # GS-2250DL both have 2.250" inner diameters and 3.376" outer diameters so they are compatible. If you are in the process of changing out your bearings and seals, I have added links to help articles on how to replace them as well as a link to our entire selection of bearings, races and seals for you to check out.

  • Recommended Hydraulic Disc Brake With E-Coat Conversion For 7,000 lb Tandem Axles
    For your Lippert 7,000 lb axles, I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs, # K2HR712E. This will give you the 1/2 inch lugs but not the oil bath as you mentioned. For this assembly, I recommend the # BK3-200 Bearing kit. For easy maintenance and monitoring, I recommend the Bearing Buddy Bearing Protectors - Model 2441 - Chrome Plated (Pair), # BB2441. The Oil Bath option is only available with the 9/16 inch lugs in the Kodiak Disc Brake...

  • Can Oil Seal be Used in Place of Grease Seal on Trailer Hub
    A grease seal like the part # GS-2250DL would be your best option if that is the size you need. You can go to an oil seal like with the Unitized Oil Seal for Trailer Hubs # 10-63 which is same size and it would work but it's not going to be considerably more effective or reliable than a grease seal. It might be a little bit better in how it would work out but the price is much higher.

  • Availability Of Oil Bath Hubs For Boat Trailer With 7000lb Axles
    There are a few options for oil bath hubs for a boat trailer with 7000lb axles though I will start with saying that oil bath hubs are not recommend for a boat trailer due to the oil braking down very fast when water is introduced unlike grease. The first is a disc brake option which is the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - Dacromet and Stainless - 7,000 lbs # K2HR712DS. This system includes races but you will need inner bearing # 25580 and outer bearing # 14125A. Now...
