Ultra-compact linear guide system optimized for space-constrained precision applications. Features hardened raceways (HRC58-62) with 4-row circular arc groove design for smooth motion and high moment resistance. The S10APT suffix indicates stainless steel end seals (S), 10μm precision class (10), auto-lubrication prep (A), phosphate treatment (P), and Teflon-coated rollers (T).
- Medical device positioning stages
- Semiconductor wafer handling robots
- High-speed PCB drilling machines
- 3D printer X/Y axis systems
- Optical inspection equipment slides
- Laboratory automation sample handlers
Installation protocol:
Use torque-controlled mounting (0.8-1.2Nm for M3 screws) with sequential
tightening pattern. Maintain 0.02mm/m straightness tolerance during rail
alignment. For 220mm travel, ensure minimum 30mm overrun at both ends.
- Prevent abrasive particles >15μm from entering raceways
- Relubricate every 6 months in normal environments
- Use AE-type lithium complex grease only
- Max side load: 15% of static capacity
