Precision adjustable stroke cylinder featuring micro-adjustment capability (±0.5mm accuracy) through its unique dual-stage locking mechanism. The 75S variant includes a shock-absorbing end cap with 3-position cushioning adjustment (soft/medium/hard). Designed for applications requiring precise stroke modification without disassembly.

Typical Applications:
  • Die height adjustment in injection molding machines
  • Workpiece positioning in CNC automation systems
  • Pressure-sensitive clamping devices
  • Variable stroke applications in packaging lines
  • Semiconductor wafer handling equipment
Installation tip: Always perform stroke adjustment at mid-pressure (0.3-0.5 MPa) for optimal precision. Lubricate adjustment threads monthly with ISO VG32 hydraulic oil.
Critical note: Avoid full extension/retraction during adjustment. Maintain minimum 5mm residual stroke to prevent seal damage from over-compression.
