Product detail
The BK10 / BF10 Ball Screw Support Units are high-precision end supports designed to provide stable and accurate mounting for ball screws in CNC machines, automation systems, and linear modules.
Each set consists of:
BK10 (Fixed End Support) — equipped with preloaded angular contact bearings, ensuring high rigidity and zero axial play.
BF10 (Floating End Support) — designed for smooth shaft rotation and thermal expansion compensation.
These supports are manufactured from high-quality bearing steel with precise machining and surface treatment, ensuring low noise, high durability, and superior alignment accuracy during high-speed motion.
