works well February 13, 2015
Reviewer: ma1 from VA  
Works well with the 12mm shaft, no noticeable play.   I bought INA (German) KH1228 from another vendor, and that one has a lot of play (the inside is not 12mm).

Reviewer: adjure  
Glad they called to say no stock  think they should have adjusted shipping cost to reflect the change in the order.

A fraction more friction.. November 28, 2011
Reviewer: Joe User from Vancouver, BC, Canada  
Purchased a linear bearing for use in a laser CNC  but the new bearing had more rolling friction than the damaged one it was replacing.  Ended up cutting the damaged end piece off of the old bearing and using it instead  keeping the new one from vxb as an emergency backup.

Works Very Well February 1, 2011
Reviewer: Alan the Tinkerer from Chicago Area Illinois  
This bearing slides vertically along the shaft very well. It's not made to spin around though. You can't beat the price. Good Bearing!
