Ultra-precision linear motion system with 90° V-V groove configuration, featuring alternating orthogonal rollers for exceptional moment load resistance. The optimized crowning design reduces edge stress concentration by 40% compared to standard models. Includes hardened raceways with mirror finish (Ra≤0.1μm) and anti-creep side locks.
- High-speed CNC grinding machine Z-axis positioning
- Semiconductor wafer inspection equipment stages
- Pharmaceutical tablet press upper punch guidance
- Optical fiber alignment systems
- 6-axis robotic arm wrist joints
Installation note:
Requires mounting surface flatness ≤5μm/100mm and parallelism ≤8μm.
Use 4.5Nm torque for M5 mounting screws with Loctite 243 threadlocker.
Break-in period: 50 cycles at 20% rated speed before full operation.
