Ultra-compact crossed roller guide featuring bi-directional equal load capacity and minimal elastic deformation. The hardened V-groove raceway design achieves 30% higher rigidity than standard linear guides. Anti-creep construction prevents roller slippage during high-acceleration movements (up to 50m/s²). Includes built-in alignment notches for simplified multi-axis system assembly.
- High-speed PCB drilling/spindles (X-Y-Z stages)
- Semiconductor wafer inspection equipment
- Precision rotary-to-linear motion conversion units
- Medical CT scanner gantry positioning
- Optical lens polishing machines
Installation Protocol:
Maintain rail parallelism within 0.01mm/m using laser alignment.
Apply 0.8-1.2Nm torque for M4 mounting screws with Loctite 243.
Run-in at 20% max speed for 30 minutes before full operation.
