While these aren't the best linear bearings, they're pretty good and they're excellent for the price point.Very happy with them.

My old blocks were all gummed up with milled rubber flakes and these rejuvenated my machine. Running like new now.

Was looking for SS bearings in these blocks, but was unable to locate any.So the price is low enough to swap them after they rust in a wet environment.

Installed two of the new SBR16UU Bearing Block on the new rails.The previous reviews were "spot on" - order spare assets!
