Good value for industrial use

Works well for the price. Fit was slightly tight on the housing but manageable.

Exactly what I needed

Replaced old bushings with these. Much quieter and smoother linear motion.

Smooth operation on my 3D printer

Installed the 12mm bearing on my Z-axis. Very smooth movement and easy to press fit.
