Ultra-compact linear motion solution featuring a unique 45° contact angle roller design that optimizes moment load resistance. The chrome-plated rail with mirror finish (Ra≤0.2μm) ensures smooth motion characteristics, while the pre-loaded carriage eliminates backlash for precision positioning. Includes anti-creep design for vertical installations.
- High-speed PCB component placement robots
- Optical lens coating equipment stages
- DNA sequencing instrument X-Y platforms
- Semiconductor wafer inspection systems
- 3D printing extruder carriage assemblies
Mounting protocol:
Requires torque-controlled installation (0.8-1.2Nm for M3 screws) with ≤0.02mm/m
alignment tolerance. For maximum service life, perform initial lubrication with
ISO VG10-15 grease and replenish every 100km of travel.
