  • Variable position clamping in CNC fixture systems
  • Material handling with adjustable lifting heights
  • Packaging machine product height compensation
  • Glass cutting equipment pressure adjustment
  • Automated welding positioners
Installation Guidelines:
  • Mounting surface flatness ≤0.1mm/m
  • Lubrication: ISO VG32 turbine oil recommended
  • Adjustment procedure: Loosen lock nut → rotate stopper → torque to 15N·m
  • Max side load: 150N at full extension
  • Maintenance cycle: Relubricate every 500km of cumulative stroke
Critical note: Always engage mechanical lock before performing stroke adjustments under pressure. Avoid continuous operation above 0.7 MPa for more than 2 hours.
