High-precision adjustable stroke cylinder featuring dual-position locking mechanism with graduated scale for micron-level positioning accuracy. Integrated shock absorption system reduces end-impact noise by 40% compared to standard models. Designed for applications requiring repeatable mid-stroke positioning without mechanical stops.
- Variable height clamping in CNC fixture systems
- Position-adjustable pressing mechanisms in PCB assembly
- Material feeding systems with dynamic stroke control
- Packaging line product height compensation units
- Automated welding positioners with Z-axis adjustment
Operation guidance:
Always unlock the stroke adjustment screw (M6 hex key required) before repositioning.
Apply silicone grease monthly on the adjustment rail. Avoid side-load forces exceeding 120N.
Critical note:
Requires minimum 3-bar pressure for stable position locking.
Do not disassemble cushion valves during stroke adjustment.
Maximum lateral load capacity: 1.5× standard series cylinders.
