Precision adjustable stroke cylinder with mechanical stroke adjustment mechanism, featuring dual-position locking for stable stroke setting. The built-in shock absorber minimizes end-impact noise. Ideal for applications requiring variable positioning without disassembly. Requires ISO 8573-1 class 3 or cleaner compressed air.

Typical Applications:

• Variable height positioning in assembly lines
• Material handling with adjustable clamping force
• Press machine tooling with depth control
• Packaging equipment with product size variations
• Automated welding jigs requiring multi-position stops

Adjustment procedure: Loosen lock nut → Rotate adjustment screw (1 full rotation = 2mm stroke change) → Tighten lock nut while holding screw position. Perform adjustments only when cylinder is depressurized.

Lubrication: Pre-lubricated design (maintenance-free for 2,000km operation). For heavy usage, add 1-2 drops of ISO VG32 turbine oil monthly through air line lubricator.
