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.

Ask the Experts about this Dexter Axle Trailer Bearings Races Seals Caps

  • 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.

  • Does Unitized Oil Seal for Trailer Hubs 10-63 Require Sealant
    I contacted Dexter and the Unitized Oil Seal for Trailer Hubs part # 10-63 do not require RTV sealant or a gasket maker. They are typically used in oil bath hubs. I have attached an installation video for your reference.

  • 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.

  • 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...

  • Oil Seal For Dexter Axles Matching Size Of Dexter 10-36 Grease Seal
    For an oil seal matching the inside and outside diameter of the 10-36 grease seal, you will want the Unitized Oil Seal for Trailer Hubs # 10-63 for your Dexter axles. You can also use the Oil Seal # 9103309 confirmed to fit Hayes axles of the same size. Hayes was bought out by Dexter.

  • How to Choose the Correct Seal for Gooseneck Trailer
    In order to choose the correct oil seal for your gooseneck trailer you will need to measure the inner and outer diameter of your current seal to the thousandths and measure your spindle at the the seal surface using a digital caliper like # 301-17068. These measurements will allow you to choose the right seal; I've added a link to our page with each of our oil seals for you to take a look at.

  • Purpose of the Metal Plate on Unitized Trailer Hub Grease Seals
    The unitized seal part # 10-63 has a metal plate that attaches and stays fixed to the spindle and the outer rubber piece will rotate with the hub. This is the kind of seal that is used on oil bat hubs and this particular one is for 8k rated Dexter hubs.

  • Replacement Seals, Castle Nut, and Oil Cap For 2011 Carto Mate Car Hauler
    In order to know what the correct seals, nut and oil cap, I need to know what spindles you have on your axles. If you can provide me with caliper (like # PTW80157) measurements or bearing numbers for your inner and outer bearing (printed on the face of most bearings), I can help you with the parts you need. Measurements of your hubs with the caliper would also be very helpful for a confirmed fit. Please see attached photo.

  • Parts Needed to Convert Electric Brakes to EOH System on Triple 7K Axle Toy Hauler
    We do have a complete kit to convert your triple 7K axle trailer to an EOH setup! I recommend using the HydraStar Disc Brake Kit w/ Actuator # HSE7K-TR1 which come with the EOH actuator, disc brake hub/rotors, and the brake line parts needed for all 3 axles. The only other parts you'll need are a junction box like # e99011 and a breakaway kit like # 50-85-315 (but you should have both of these since you currently have electric brakes). The junction box gives you a 7-Way connector on your...

  • 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...

  • 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.

  • Oil Bath Seals for Kodiak Disc Brake Kit for 7K Axles and 8 on 6-1/2 Bolt Pattern
    Yes, using oil bath hub seals # 10-63 will work with the Kodiak disc brake kit you ordered, # K2HR79E. The kit already has the oil caps so you wouldn't need those. The brake kit does not include the bearings. You would need 2 of # 25580 and 2 of # 02475.

  • Recommended Disc Brakes 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. I've attached a photo and article to assist. For your disc...

  • 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...

  • 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...

  • Recommended Electric Brake Magnet And Hub Components For Dexter 9000-Lb Axle
    The Replacement Magnet Kit for your Dexter 12-1/4 inch brake assemblies is part # BP01-301. The kit includes the magnet, the spring, and the clip. For a Dexter 9K system manufactured after October 1989, the unitized seal you need is part # 10-51. If your axle was made before October 1989 the seal you need is part # 10-63. The Oil Cap Kit is part # RG04-270. This kit includes the cap, O-ring, and plug.

  • What Is The Correct Oil Seal For A Dexter 9K Axle Pre-1989?

The inner part stays fixed on the spindle and the outer casting rotates with the hub. This type of seal has less wear and tear to provide better leak protection.

    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...

  • 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.

  • Kodiak Trailer Disc Brakes for 7,000 lbs AL-KO Axles
    Yes, it is safe to assume that a 7K axle from AL-KO built in 2014 will have standard spindle and brake mounting specs. It looks like you were looking at disc brakes. If that is the case, the Kodiak Disc Brake Kit, # K2HR79E, that you came from will fit your axles. The bearings and seals are sold separately, so I listed them for you below Inner bearing - # 25580 Outer bearing - # 02475 Grease seal - # RG06-070 or Oil seal - # 10-63 You will need two of each part number.

  • Recommended Grease Seal for Dexter Trailer Axle Beam # 7461121
    The Dexter Trailer Axle Beam with E-Z Lube Spindles - 95" Long - 6,000 lbs # 7461121 will use a grease seal is the inner diameter of 2.25 inches. The outer diameter is the 3.376 you mentioned, so for this combination the seal is # 10-63. If you want complete hub assemblies including bearings races and seals needed compatible with that axle, I recommend the Dexter Trailer Hub and Drum Assembly # 8-201-9UC3-EZ which is a confirmed fit and braking assemblies # AKEBRK-7-SA.

  • Recommended Hydraulic Disc Brake With E-Coat Conversion For 7,000 lb Tandem Axles

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.
