Ultra-compact linear guide system optimized for precision motion in confined spaces. Features four-row circular arc groove design with 45° contact angles for balanced load distribution. The HT-treated rail surface provides enhanced corrosion resistance, while the dual sealing system (BHT suffix) ensures extended service life in dusty environments. Requires periodic lubrication with ISO VG15-32 grease.
- Medical device positioning stages
- Semiconductor wafer handling robots
- Desktop CNC engraving machines
- 3D printer X/Y axis systems
- Automated optical inspection (AOI) equipment
Installation note:
Maintain 0.02mm/m alignment tolerance during rail mounting.
Use torque-controlled tightening (1.2-1.5N·m for M3 screws)
to prevent carriage deformation. Avoid side-load impacts exceeding 30% of static capacity.
