Precision-adjustable pneumatic cylinder featuring dual-position locking mechanism for millimeter-level stroke control. The corrosion-resistant design incorporates a hard-anodized aluminum barrel and triple-lip rod seal for harsh environments. Includes magnetic piston for position sensing compatibility.

Typical Applications:
  • Precision clamping fixtures in CNC machining centers
  • Variable height positioning in automated assembly lines
  • Material feeding systems requiring stroke adjustment during operation
  • Packaging machine pusher mechanisms with space constraints
  • Semiconductor handling equipment needing contamination control
Installation guidance: For optimal performance, align cylinder axis within ±0.5° of load direction. When adjusting stroke, loosen locknut before rotating stopper (max torque 2.5N·m). Maintain 15mm clearance behind end cover for stopper adjustment.
Maintenance protocol: Relubricate every 500km of cumulative travel distance. Replace wiper seal annually in high particulate environments. Avoid side load exceeding 30N to prevent rod bearing wear.
