Precision adjustable stroke cylinder featuring dual-position mechanical stops for mid-stroke positioning. The tungsten-impregnated piston rod provides exceptional wear resistance in high-cycle applications (up to 15 million cycles @ 0.5MPa). Integrated magnet allows position feedback when used with sensors (SM/SD series). Requires ISO VG32 hydraulic oil lubrication for optimal performance.
- Precision clamping in CNC tool changers
- Variable stroke control in semiconductor handlers
- Force adjustment systems for press-fit operations
- Packaging machine stopper positioning
- Automated test equipment with stroke calibration
Adjustment procedure:
Loosen lock nut (M12) → Rotate cushion screw (clockwise to shorten stroke) →
Tighten at 3.5-4.5N·m torque. Always depressurize before adjustment.
Critical notes:
Avoid side loads exceeding 15N. For vertical mounting,
use rod-end support bracket (ASM-10 accessory recommended).
Minimum 5μm filtration required.
