Linear Slide Lubrication: Selecting the Right Grease for High-Speed and Cleanroom Assembly
- Linear guide and ball screw service life is dominated by grease formulation. Improper grease selection causes fretting wear, particle contamination and torque drift. This article defines grease selection criteria for high-speed operation and ISO 14644 cleanroom assembly.
Lithium complex grease delivers stable performance under normal temperature and moderate load, with lower procurement cost. PAO synthetic grease maintains consistent viscosity under wide temperature variation and reduces particle emission for cleanroom use.

FAQ
Q: What is the typical changeover time to replace grease on linear motion modules?
A: Full grease flush and re-lubrication takes 18–28 minutes per axis. Complete solvent cleaning of ball circuit adds 25 minutes.
Q: Are spare parts compatible with Panasonic and SMC global supply chains?
A: All linear module grease fittings and seals adopt standard industrial specs, compatible with global SMC, Panasonic and Festo part inventory.
Q: What Cpk threshold is required for FAT acceptance on lubricated linear slides?
A: FAT acceptance requires Cpk ≥1.67 on repeatability test, measured at 3 different stroke positions.
