Typical Applications:
  • Packaging line product positioning gates
  • CNC machine tool clamping mechanisms
  • Automated assembly station press-fit operations
  • Material handling systems with variable stroke requirements
  • Printing press roller engagement controls
Installation note: For optimal performance, maintain 0.5-1mm clearance between cushion screws and stopper. Lubricate with ISO VG32 hydraulic oil. Maximum side load: 30N. Not recommended for vertical downward thrust applications without external guides.
