Ultra-compact linear guide featuring hardened raceways and precision-ground rolling elements. The LRM12 series delivers smooth motion with 0.005mm repeatability, optimized for space-constrained automation. Preloaded ball bearings (S10 class) eliminate mechanical play while maintaining low friction coefficient (μ<0.003). Includes anti-creep design for vertical installations.
- Medical device positioning stages
- Semiconductor wafer handling robots
- High-speed 3D printer X/Y axes
- Optical inspection equipment slides
- Laboratory automation sample handlers
Installation note:
Requires surface flatness ≤0.01mm/m on mounting base. Use torque-controlled screwdriver
(0.7-0.9N·m for M4 screws) in cross-pattern sequence. Lubricate with ISO VG15-32 oil
before initial operation.
