Ultra-compact linear guide system featuring precision-ground raceways and optimized ball circulation. The LRM12 series combines high rigidity with minimal space requirements, utilizing staggered ball groove design to reduce vibration harmonics. Includes anti-creep seals and corrosion-resistant treatment for maintenance-free operation in contaminated environments.
- Precision laboratory instrumentation stages
- Medical device linear actuators
- Semiconductor wafer handling robots
- Desktop 3D printer X/Y axis systems
- Optical lens positioning mechanisms
- Automated microscope slide scanners
Installation guidance:
Mount on machined reference surface with flatness ≤0.01mm/100mm.
Use 0.5Nm torque for M3 mounting screws. Apply thread-locking compound
for high-vibration environments. Lubricate every 100km travel or 6 months.
