Introduction
Ball Screw Bearing Block is the axial support unit that determines positioning repeatability across the entire linear drive assembly. Baili's bearing blocks are factory-preloaded and pre-lubricated, installing directly without on-site clearance adjustment - a detail that reduces machine assembly time and eliminates field calibration errors. Available in fixed-end (BK/EK) and support-end (BF/EF/FF) configurations, each ball screw bearing block pairs directly with Baili's own ball screw range and is dimensionally compatible with finished-end screws from THK and NSK without additional shaft machining.
