Do all 3,500 lb Trailer Axles Have the Same Bearings

Question

Question:

Im installing brakes on a 3500lb axle for the first time trailer has never had brakes. I have backing plates but need to get bearings and brake hubs. pretty sure they are 5 on 5 pattern. I will double check before I order. Are the bearings all the same part numbers on all 3500lb axle? or will I need to tear mine apart to get numbers off the bearings I have now?

In almost all cases 3,500 lb axles will all use the same bearings. If your trailer has a Lippert or Dexter 3,500 lb axle then yeah they would be the same. But to be safe it won't hurt to pull them off and get the numbers.

If you are sure you need a 5 on 5 inch bolt pattern we have the part # AKHD-550-35-K which would work and fit the spindle. This hub uses bearing numbers L68149 and L44649.

I attached a help article on bolt patters for you to check out as well.

Hi Tony; the #BK2-100 and #TMK52VR come with the same size bearings and grease seal. The main difference is the Timken name. This is usually associated with a higher quality bearings that are made in the USA which also accounts for the higher cost.

Yes, the Timken Bearing Kit #TMK52VR will fit your 3,500 lb axle as it fits an standard #84 spindle. The only time this kit won't fit with a 3,500 lb axle is if the trailer/axle is made before the 2000's since that's about the time that…
