Ultra-slim profile cylinder with precision stroke adjustment, featuring dual anti-rotation design for stable positioning. The hardened stainless steel piston rod and self-lubricating bearings ensure smooth operation under high side loads. Integrated auto-locking mechanism prevents accidental adjustment during operation.

Typical Applications:
  • Precision alignment in semiconductor wafer handling
  • Variable stroke requirements in packaging machinery
  • Space-constrained automation cells (robotic end effectors)
  • Medical device assembly with cleanroom requirements
  • Flexible jig positioning systems
Operation tip: For optimal performance, lubricate adjustment threads with silicone grease (ISO VG 10 grade) monthly. Maximum side load capacity 35N at mid-stroke. Avoid full extension adjustments under pressure.
