Engineered for ultra-precise linear motion systems requiring minimal deflection, the LGC1A30R11-H features staggered 90° angular contact rollers that eliminate clearance while maintaining smooth motion. Its hardened stainless steel raceway (HRC58+) ensures extended service life in contaminated environments. The optimized roller path geometry reduces edge stress concentration by 40% compared to conventional designs.
- High-speed CNC grinding machine Z-axis guidance
