Ultra-compact linear guide optimized for precision motion in constrained spaces. Features hardened raceways (HRC 58-62) with corrosion-resistant treatment, supporting high moment load capacities (Mx=4.2Nm, My=5.1Nm, Mz=4.8Nm). Includes pre-loaded ball bearings for zero-backlash operation and integrated debris-resistant sealing.
- Medical device positioning stages
- Semiconductor wafer inspection equipment
- 3D printer X/Y axis mechanisms
- Laboratory automation slide systems
- Precision optical alignment devices
- Robotic end-effector guidance
Installation guidance:
Mount on precision-machined reference surfaces (flatness ≤0.02mm/m).
Apply lithium-based grease (NLGI #2) through carriage lubrication ports
every 50km of travel. Avoid side-loading during assembly - maximum
permissible alignment error: ±0.05mm.
