Heavy-duty crossed roller guide featuring alternating orthogonal roller arrangement for exceptional moment load resistance. The LGC2A90R19-H combines high rigidity with smooth motion characteristics through its unique 45° contact angle design. Hardened raceways and precision-ground rollers ensure consistent performance under repeated high-stress cycles.
- CNC rotary table bearing systems
- Precision grinding machine Z-axis guides
- Semiconductor wafer handling robots
- Optical measurement equipment stages
- High-payload Cartesian coordinate robots
Installation requirements:
Requires mounting surface flatness ≤0.02mm/m and surface roughness Ra1.6μm.
Use torque wrench for M8 bolts (22-26N·m). Perform initial lubrication every
100km travel or 6 months (whichever comes first) using ISO VG68 equivalent grease.
