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