How to Pick Out Bearings for a Dexter P-21 SLR Axle  


I recently purchased a flat bed trailer with 2 Dexter p-21 model slr axles under it. All 4 of the hub assemblies bearings are shot and need to be replaced. Is there any other info you will need to be able to tell me what I need go them? Thanks,

We checked with Dexter and P-21 just indicates where the axle was made. With the serial number we could track down more info on your axle.

However, in the mean time you could pretty easily get the bearing numbers off of your current bearings and then check out the link I attached to see what each bearing kit contains to see which would work.

There are two different bearing kits that would MOST LIKELY work for you.

If you need a seal with a 2-1/8 inch inner diameter you would need the part # BK3-210. If you need a 2-1/4 inch seal you would need the part # BK3-200. The bearings of this kit are 14125A/ 25580. If the bearings on your trailer now have those numbers stamped on them either kit would have the right bearings.

You will need to remove the hub and measure the diameter of the spindle where the seal rides to see which kit you would need if you can't get the bearing numbers.
