NSK FA Type Ball Screw Core Features
Finished Shaft End Machining: NSK completes both thread machining and shaft end machining, enabling mass production of standard products, significantly shortening delivery cycles and facilitating immediate installation and use.
Compact and Lightweight: Designed specifically for small FA (Factory Automation) equipment, maximizing space utilization and featuring a lightweight structure.
Preload Method: Typically employs P-preload, achieving smooth operation while maintaining high rigidity.
High Precision: Belongs to the precision-grade series, suitable for working environments requiring high positioning accuracy.
Compatibility: Typically used with NSK's BSBD series angular contact ball bearings (for supporting ball screws), providing complete support solutions.
FA type ball screws are widely used in compact transmission systems with high precision requirements:
Small Precision Machinery: Electronic component assembly machines, small machining centers.
Automation Devices: Precision worktables, measuring instruments, feeding mechanisms.
