They look pretty good, but they sure are big.

If you can get the bearing numbers on these bearings i can check in my bearing book what speeds, loads etc these bearings are rated for.

Those are like mine on my gate.
They are Casters with a V cut not Bearing with a V cut.
They are not real acurate.
They are 4 inches around by 2 inches wide. I think they weigh about 3 pounds.

Notice the shipping charges? Almost $10.00 ea. That $5 bearing will cost $15 to get it home.
