Ultra-low profile linear motion solution featuring high rigidity-to-size ratio, optimized for space-constrained automation. The hardened rail and precision-ground balls provide smooth movement with ≤25dB operational noise. Includes integrated alignment grooves for simplified installation.
- Precision microscope stage positioning
- Medical device linear actuators (IV pump mechanisms)
- Semiconductor wafer inspection equipment
- Desktop CNC Z-axis guidance
- 3D printer gantry systems
- Robotic joint articulation (≤5kg payload)
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled screw tightening sequence (M3 @ 0.5-0.6Nm) to prevent rail deformation. For vertical applications, install grease nipple (accessory port on block top) facing upward.
