Ultra-compact linear motion solution combining high rigidity and smooth movement in constrained spaces. Features pre-loaded balls (2% C) for minimal deflection during start-stop operations. The chrome-plated shaft and hardened raceways ensure >2,000km travel life under proper lubrication (VG68 grease recommended). Includes alignment marks for simplified installation.
- Medical device sliding mechanisms (MRI components, surgical arms)
- Semiconductor wafer inspection equipment X-Y stages
- Precision optical lens adjustment systems
- Desktop CNC engraver Z-axis guides
- High-speed pick-and-place robotic end effectors
Installation criticals:
Ensure rail flatness ≤0.02mm/m using granite surface plate for reference.
Use 0.3-0.5Nm torque for M3 mounting screws in cross-pattern sequence.
Apply initial lubrication to all ball tracks before first operation.
