Outer Trailer Bearing HM212049 & Matching Up Inner Bearing  

Question:

I have a trialer that has had a bearing blowout. The one bearing I have found remaining is number hm212049. Was curious about matching up the inner bearing with that number if possible. Unfortunately the trailer is a logging trailer and is not got any markings remaining anywhere due major log woods usage.

We do have the bearing and matching race you mentioned, the outer bearing # HM212049 and race # HM212011.

This is for a 22,500 lb or 25,000 lb axle, and the only matching option we have is bearing # HM218248 and race # HM218210.

The only way to determine if that is right for your trailer though is to use a digital caliper and measure the spindle where the bearing rides; if that is 3.542" then the # HM218248 is correct.
