A precision-engineered adjustable stroke cylinder featuring dual-scale position indicators (0-125mm main scale + 0-100mm adjustable scale) for micron-level positioning accuracy. The anodized barrel resists corrosion in humid environments, while the chrome-plated piston rod ensures smooth operation at speeds up to 1.5 m/s. Includes built-in magnet for sensor mounting.
- Precision clamping fixtures in CNC machining centers
- Variable height adjustment in conveyor systems
- Material handling robots requiring position feedback
- Packaging machine stopper mechanisms
- Semiconductor wafer handling equipment
Installation note:
For optimal performance, maintain 0.5-1mm clearance between the adjustment screw and mechanical stop during calibration.
Lubricate with ISO VG32 hydraulic oil if operating below -10℃. Avoid side loads exceeding 30N.
