Today we're going to review part number 506810. This is the Redline bearing race. This bearing race is designed to fit the bearing part number 506849. This bearing race, this part will install into your hub assembly. It gives it a seat for the wheel bearing to sit into. The rollers on the wheel bearing will ride on the inside taper of this bearing race.
It does have the part number on it, stamped right there, 506810. The important part of this part number is the outside diameter measurement. It does have to be correct to fit into the hub assembly on your trailer. It is measured in thousandths of an inch. We are going to use a digital caliper here to get a correct measurement for you.
The outer diameter on this part number will be 3.543. That should do it for our review on part number 506810. .

After some explaining to the owner of the trailer that none of these bearings were intended for high speed highway miles at least not many hes taken it easy on this ancient trailer. So far, everything works very well, with no grease leaking past seals and all the bearings carrying their weight well.
