Question:
I have a new National trailer and it came with sealed bearings from RA Rock Solid. Im not familiar with sealed bearings and only hear that they dont need to be greased like standard hubs or often. My question now is, where can I get an additional one for a backup spare ? Does it need to be the same as the manufacturer I currently have on the trailer ? And how do I replace them when needed ? Ive looked on the internet and Im not having much luck educating myself on this type of bearing. Any help would be appreciated. Respectfully,

Expert Reply:
We offer three sealed bearings so you will need to take some measurements to see if they will work for you. If one of these matches the dimensions of the bearings you have then you can use it as a spare.
Our Redline Nev-R-lube Bearing # 31-73-3 measures 42mm I.D. x 76mm O.D. x 39mm wide.
For Bearing # 31-71-3, the measurements are 50mm I.D. x 84mm O.D. x 54mm wide, and bearing # 31-72-3 has a measurement of 35mm I.D. x 64mm O.D. x 37mm wide.
