Stainless Steel 5mm Deep U Groove Ball Bearings Pack of 2, Pulley Bearing Wheel Rail Ball Bearings Wheel

Very heavy duty which is good using it to make some barn door window coverings

As described, arrived early then estimated. Will buy again if needed

Center bore is 1/16 smaller that the 1/4 that is states. True measurement is 3/16.

I used these on a farmhouse door build. The ball bearings made the doors slide effortlessly and the V-groove on the pulleys kept the pulley centered on the rail.

aaa+

These salvaged our zip line, which has been neglected by the kids because it no longer zipped. The new bearings where a perfect fit, and the zip line works perfectly now.

Work just as expected and timely delivery!

high quality product

So much better than the original ones. My zip line is up and running again.
