Ultra-compact linear motion solution combining rail and ball screw drive in one unit. Features preloaded ball bearings for zero-backlash operation and hardened steel raceways for extended service life. The integrated wiper system maintains lubrication while excluding contaminants. Optimized for high-speed applications up to 2m/s with vibration damping characteristics.
- Precision XYZ stages in semiconductor inspection
- Laser cutting head positioning systems
- High-speed pick-and-place robotic arms
- Medical analyzer reagent handling mechanisms
- 3D printer extruder carriage systems
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Apply lithium-based grease to ball screw
before initial operation. Avoid side-load impacts exceeding 30% of static moment ratings.
Thermal expansion compensation recommended for installations exceeding 500mm travel.
