12mm CNC Bushing Linear Bearing Block Open Linear Motion

Our project worked out very well. This was a prototype and we would use your bearing for the production.

I have to do a lot of redesign work to make these work. Drawing is off on pretty much every dimension - very frustrating.

Used on my CNC machine build Y axis works great however several ball bearings came out of the block during installation of the Z axis. Need to reorder or return..
