The perfect size and quality seal for my camper trailer.

A bit pricey, but good quality seals. Installed on my travel trailer and tested with a 1000 mile trip. No issues.

Overall service was great between 2 different people, but I still got the wrong parts sent and cannot get anyone to respond to my calls or emails... Not a real happy customer right now!!!!



by:

Good quality axle grease seal



by:

Perfect fit for my 6K Dexter axles on my 337RLS Reflection RV. Seem to work great. I haven't seen any sign of grease migrating beyond the seal.



by:

The team at etrailer are not only knowledgeable but also fantastic at resolving issues and making right by their customers. They really know their products and provide exceptional customer experience.



by:

Grease zerk in spindle end . Pumping grease from inner bearing to outer bearing the seal did not leak . Very Good.



by:

Don’t waist your time and money on cheap stuff. Timken is one of the best and for good reason. Factory seal wore out and covered brake assembly. I had to replace brake assembly because of a $5 cheap seal. Replace your seals with name brand and have no worries.

Seal ordered was 440972 but it looks like the part # shipped 413470 is the same size, my fingers are crossed.

happy to have all the correct parts



by:

These seals fit perfect! The last people I paid to repack the bearings on my installed the wrong seals! My trailer is 30 years old but well maintained. Finding the right seal was a huge problem. Everywhere I went no one could find me the right ones. So searched for them myself on line and found these on etrailer. I really didn't know if they were going to work but ordered them anyway. They took 13 days to get here but when they finally did I took one out of the package slipped it over the spindle and it fit perfect! Thanks etrailer for being the only parts supplier to have the right seal for my application!



by:

I like using Timken products. I trust them to be good quality and value.



by:

Timken top quality! Thank you Etrailer!

  • Replacement Seal For a Timkin 413470 and National 440972
    Hey, Bruce. Thanks for your question. That 413470 number you have actually comes back as a Timken seal. It also crosses over to National seal # 440972, so you’re definitely on the right track. We have that same Timken seal available as part # TMK38ZR, so it would be a perfect match for what you already have. We also offer the TruRyde Grease Seal # RG06-090, which has the same inner and outer diameters, so it will fit the same as the Timken seal. What kind of trailer are you running this on?

  • Looking For Bearing Kit For 2017 Jayco Northpoint With Lippert 7K Axles
    Hello George. We will undoubtedly have a bearing kit for the 7K Lippert your 2017 Jayco North Point 5th wheel. That said, I do not have a way to tell you the exact seal size based on the info you provided. The best way to find this out will be to remove one of the hubs and measure the ID of the seal with a caliper. It seems like the 2.250 ID seals are a bit more common, but both sizes are out there. A lot of times what I recommend folks do is just get the bearing kit like part # TMK92VR...

  • 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.
