Looking For Bearing Kit For Old 1960s Trailer

Updated 09/25/2025 | Published 09/19/2025

Question:

Hello, I have a boat trailer that I have removed the ruined bearings from the spindle. Ive taken measurements as recommended by a post I found on your website and Im hoping someone on your staff can help me determine what size bearings I need. My trailer is from the 1960s. The measurements are as follows: Spindle Shaft Length: 1.288 inches Spindle shaft diameter: 1.510 in Grease seal diameter: 1.2505 in Inner bearing diameter: 1.0115 in Outer bearing diameter: 1.0045 in Thread diameter for spindle nut: 0.9935 in. Please help me determine which parts I need to reassemble and replace the rest of the bearings on this trailer if you can. Thank you and have a nice day.

Hello Richard, thanks for reaching out. I am sorry to say we do not offer a hub or bearing kit that matches your specs. Many older trailers from back then use parts and sizing that is now obsolete, and it sounds like this is the case with your trailer. There just aren't any hubs made today that will fit.

The only solution here would be to have new spindles welded to your trailer, or to replace the axles with something more modern. New spindles can be tricky and must be welded on by a professional axle shop. New axles are easier to replace, we would jsut need to pinpoint exactly which axle you need based on hub face and weight capacity.

If this is something you want to look into just let me know. I am happy to assist in any way I can.

The hubs are fine, I'm attempting to find bearings and races to replace the old ones. If you don't offer those, perhaps Whistler Bearings could make some. Thanks.

@RichardP I gotcha yes those are going to be tough to find. If you know of somewhere that could make them for you, I would definitely go that route.
