High-precision adjustable stroke cylinder featuring dual-position locking mechanism for mid-stroke positioning. The SEJ63X80-40 combines position memory capability with shock-absorbing adjustment screws that allow ±20mm stroke modification without disassembly. Special chromium-plated rod surface treatment reduces stick-slip effect during low-speed operation.

Typical Applications:
  • Precision clamping fixtures in CNC machining centers
  • Variable height positioning in automated assembly lines
  • Material handling systems requiring multi-position stops
  • Packaging machine pusher mechanisms
  • Glass cutting equipment with adjustable depth control
Operation note: Always lubricate with ISO VG32 hydraulic oil (1-2 drops per port) before initial use. Adjust cushioning screws while cylinder is depressurized - clockwise rotation increases damping force. Maximum allowable side load: 15N at full extension.
