Ultra-slim profile cylinder (30% thinner than standard models) with 360° rotatable cushion adjustment screws. Features dual anti-rotation guides for precise linear motion, making it ideal for space-constrained automation. The through-hole piston rod design allows external position sensing without additional brackets.

Typical Applications:
  • PCB handling robots requiring <25mm installation space
  • Medical device clamp mechanisms with sterilization cycles
  • Food packaging machines needing frequent stroke adjustments
  • Semiconductor wafer transfer systems with cleanroom requirements
Installation tip: When using the switchable mounting feature, apply 2.5–3.5Nm torque on the four M4 mounting screws. Lubricate with ISO VG32 pneumatic oil if operated below 0.3MPa.
