High-precision adjustable stroke cylinder featuring dual locking nuts for position retention, designed for repetitive positioning applications. The magnetic piston version (optional) enables position feedback detection. Anti-rotation design maintains orientation stability during long stroke operations.

Common Applications:
  • Variable height work platforms in assembly lines
  • Material handling gate controls
  • Plastic injection molding ejector systems
  • Printing press paper feed mechanisms
  • Automated welding fixture positioning
Installation tip: For optimal performance, align within 0.2mm/m perpendicularity tolerance. Lubricate with ISO VG32 hydraulic oil when using non-lubricated air supply. Allow 50mm clearance behind rod end for full stroke adjustment.
Caution: Avoid side load exceeding 15N·m. Maximum permissible piston speed: 500mm/s (cushioned) / 1000mm/s (uncushioned). For vertical mounting, always use rod-down orientation unless equipped with counterbalance valves.
