Hannah W. ★★★★★

The 3/16" inner diameter seated perfectly on my follower rest shaft, and the sealed shields mean I haven't had to oil them once in a week of running. For the price, these bearings spin true with zero play, which is all I really need for light lathe work.

Benjamin H. ★★★★★

Smooth as silk in my steady rest—these little bearings are holding up perfectly under continuous use. The 1/2" OD fit my setup without any filing or modification.

Avery ★★★★★

The 3/16" ID is spot-on for my follower rest, and the sealed shields keep the grit out during heavy cuts. Spins smooth right out of the package, no break-in wobble.
