Ultra-compact linear guide optimized for space-constrained precision applications. Features enhanced rigidity through 4-direction equal load design and corrosion-resistant surface treatment. The S7.5AH preload ensures minimal deflection during high-speed reciprocation. Compatible with automatic lubrication systems through grease nipple (M4×0.7 thread).
- Semiconductor wafer handling robots
- Medical diagnostic equipment sliding mechanisms
- High-speed 3D printer X/Y axis systems
- Precision optical inspection stages
- Laboratory automation sample handlers
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(1.2-1.5N·m for M4 screws) in cross pattern. Avoid welding sparks near guide surfaces.
