Typical Applications:
  • PCB handling robots in electronics assembly
  • Precision clamping mechanisms for CNC tooling
  • Medical device actuation systems
  • Automated packaging machine pushers
  • Laboratory sample positioning stages
Installation note: For optimal performance, maintain 0.5-1mm clearance between cylinder body and adjacent components. Use locknuts (not included) on mounting threads to prevent rotation during vibration. Lubricate every 6 months in continuous operation environments.
Adjustment Procedure:
  1. Loosen cushion locknut with 8mm wrench
  2. Rotate buffer screw (2mm hex key) clockwise to shorten stroke
  3. Test cycle rate not exceeding 120 cycles/minute
  4. Retighten locknut after adjustment
