Ultra-compact linear motion solution featuring high rigidity and smooth operation through precision-ground raceways. The chromium-plated balls (φ2.381mm) ensure low friction coefficient (μ<0.003) and quiet movement. Integrated dust-resistant design with 3-stage sealing system prevents particulate ingress in harsh environments. Requires 0.5Nm torque for mounting screw fastening.
- PCB laser marking equipment X/Y axis
- Medical analyzer slide mechanisms
- Semiconductor wafer handling robots
- High-speed sorting machine pick-and-place units
- 3D printer extruder carriage systems
Installation note:
Maintain 0.02mm/m straightness tolerance during rail mounting. Use M4×8mm flat head screws
at 120-150N·cm tightening torque. Avoid side-load impacts exceeding 300N during operation.
