– Key Features
• Interchangeable rails and ball slides permitting flexible assembly
• Modular construction supporting potentially unlimited rail lengths
• Dual lubrication ports on FA series for extended service intervals
• Low-profile design compatible with compact FA series support units
• Enhanced dust-proofing and corrosion resistance across select series
• Angular contact bearing design optimized for axial and radial load distribution
– Typical Applications
Automotive manufacturing, semiconductor processing equipment, medical device assembly, aerospace positioning systems, and precision industrial automation requiring sustained accuracy over extended operational cycles.
– Compatibility & Integration
NSK ball screws and linear guides are engineered as coordinated subsystems. The Compact FA series ball screws integrate with matching support units and angular contact bearings from the BSA series. Rail and carriage interchangeability across equivalent series enables custom stage configurations without redesign.
