A precision-engineered compact cylinder featuring micro-stroke adjustability (±5mm) through its unique screw-lock mechanism. The dual anti-rotation guide slots ensure stable linear motion, while the hardened piston rod resists side-load wear. Includes built-in magnetic sensor groove (M5 size) for position feedback compatibility.

Ideal Applications:
  • PCB component insertion machines
  • Medical device actuation systems
  • Precision jig positioning in semiconductor manufacturing
  • Compact packaging line diverters
  • Laboratory automation equipment
  • Robotic end-effector tooling
Installation guidelines: For optimal performance, maintain 0.5mm clearance between cylinder body and mounting surface. Use locknuts (included) for stroke adjustment fixation. Lubricate through air port using ISO VG32 pneumatic oil if operating below 0.3 MPa. Avoid lateral force exceeding 15N on piston rod.
