The seal we offer part # RG06-050 that you mentioned cross references as the same thing as a Transcom part 171255TB.

It would be the exact same as what you have/need.

They work great. I use them on my tow dolly and change them once a year or whenever I repack my bearing, usually annualy.

If you’re not sure if a seal fits, take the seal and check it in the end of the hub if it just looks like it just barely larger then it should fit then you check the rubber side of the seal on the spindle housing and if it fits snuggly, it’s the right seal simple

Hey Robert, welcome back! The Dexter 010-036-00, our item #RG06-070, and the Timken item #TMK58ZR are functionally the same grease seal. Timken is known for using higher quality materials in their parts so they do cost noticeably more. Both the item…

The #84 spindle is just a common way to identify the spindle dimensions typically used for 3,500 lb axles. So instead of listing out the parts, people can just say they have #84 spindles and it's easier to know what fits it. The CE Smith Trailer…

The Lippert 4,400 lb axles use the same bearings and seals as a Lippert 3,500 lb axle so you can use the Bearing Kit for #84 Spindle part #BK2-100 or just the Grease Seal part #RG06-050.
