Today we're going to take a look at the replacement bearing race for the 395S bearing. The race will provide the smooth surface area for your bearings to roll on inside of your trailer hub. Typically, if you have to get new bearings it is a good idea to also replace the bearing races at the same time. The bearing races will install into your trailer hub, they're usually pressed into place. The replacement part like this we use an industry standard number, you can see it's stamped on here, 394A for the race number. Again, the matching bearing that this is designed to fit with, we do sell separate on our website it's part 395S. The critical measurement on the bearing race is the outer diameter which is measured edge to edge.
To measure that I'm going to get a digital caliper because it is measured in thousandths of an inch. So if we get a digital caliper it'll give us the digital read out so you can see outer diameter. Let me zoom in just a little bit. Outer diameter on this is going to be 4.331 inches for the outer diameter on this race. That should do it for the review of the replacement bearing race on the 395S bearing.
Great quality and price
