Ultra-compact cylinder with mechanical stroke adjustment capability, featuring dual cushioning system for precise end-position control. The hexagonal body design enables easy wrench adjustments and space-efficient clustering. Includes built-in auto-stop mechanism at minimum stroke position for safety.

Typical Applications:
  • Precision workpiece clamping in CNC fixtures
  • Micro-positioning in semiconductor handling systems
  • Valve actuation in compact fluid control modules
  • Paper feed mechanisms in office automation equipment
  • Medical device component positioning
Installation note: For optimal performance, maintain 0.5mm minimum clearance between adjacent cylinders when clustered. Use locknut (M5x0.8) with 0.15-0.25N·m torque for stroke adjustment fixation. Lubricate every 5 million cycles under continuous operation.
