Ultra-compact linear motion solution combining high rigidity with minimal installation space. Features corrosion-resistant treatment and multi-stage sealing for harsh environments. The asymmetric rail design optimizes moment load distribution, while the precision-ground raceways ensure smooth micron-level movement. Requires periodic lubrication (recommended interval: 500km travel).
- High-speed PCB component placement machines
- Optical lens alignment stages
- Desktop CNC engraving axis guides
- Medical probe positioning mechanisms
- Semiconductor wafer inspection equipment
- Robotic joint articulation systems
Installation Tip:
Use torque-controlled tightening (0.8-1.2Nm for M3 screws) and align mounting surfaces within 0.02mm/m flatness.
Avoid side-loading during assembly - use alignment jigs for multi-rail systems.
