Precision-engineered adjustable stroke cylinder featuring a dual-position locking mechanism for stroke adjustment (±2mm accuracy). The through-rod design allows external stroke adjustment without disassembly. Integrated magnetizable piston enables position sensing compatibility. Includes wear-resistant rod scraper and anti-rotation guide for stable linear motion.
- Variable position clamping in CNC fixtures
- Material handling with adjustable lift heights
- Packaging line product positioning systems
- Automated door stroke adjustment mechanisms
- Printing press roller engagement control
Operation note:
Lubricate with ISO VG32 hydraulic oil before initial use.
For stroke adjustment: Loosen lock nut, rotate adjustment screw (1 full rotation = 1.5mm stroke change),
then re-tighten to 1.2–1.5Nm torque. Avoid over-compression beyond marked stroke limits.
