Precision multi-station cylinder with mechanical locking mechanism, featuring position repeat accuracy ±0.2mm. The integrated magnetic sensor slot enables position feedback when paired with reed switches (sensors sold separately). Anti-rotation design maintains orientation stability during multi-axis operations.
- Fixture positioning in CNC machining centers
- Modular tooling systems requiring repeatable stops
- Automated welding equipment position locking
- Palletizing robot end-effector adjustment
- Semiconductor handling precision staging
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil before initial operation.
Maintain 0.3mm minimum clearance between locking mechanism and stopper surfaces.
For vertical mounting, use model MK20X40-V with reinforced locking springs.
