Support unit croxport

Industry's first lightweight, compact and highly rigid support unit series has been made for supporting miniature ball screws of 3 to 8mm.

Light weight and compact
Weight reduced by 60% (compared with Croxport MSU - 6C)
Contributing to downsizing of equipment, weight reduction, high responsiveness
High stiffness
A miniature angular contact ball bearing Croxy series which strictly controls the preload is mounted, realizing high axial stiffness.
Comparison with market standard products
Axle core height is the same size as the standard product.
Axial load performance is equal or higher (all model numbers)

Small ball screw mounting device
