High-rigidity linear motion system featuring staggered 45° roller orientation for simultaneous radial and axial load handling. The hardened steel raceways and optimized roller geometry enable micron-level positioning repeatability (±2μm). Includes anti-creep design with integrated oil grooves for extended maintenance intervals.
- CNC rotary table indexing mechanisms
- Semiconductor wafer handling robots
- Optical lens grinding equipment
- Coordinate measuring machine Z-axis
- High-precision rotary welding fixtures
Installation note:
Requires surface flatness ≤0.01mm/m and mounting torque of 5.4N·m for M6 screws.
Perform initial lubrication with ISO VG32 grease in all oil ports before operation.
Avoid lateral impact loads exceeding 30% C0.
For vertical installations, use secondary retention brackets.
