The ASJ2912 features a micro-adjustment valve for precise damping control and maintenance-free operation. Its multi-stage damping structure combines orifice compensation and tapered groove design, effectively converting kinetic energy into thermal energy. The double-lip seal ensures leak-proof performance even under high-frequency impacts.
- Automated assembly line stopper mechanisms
- CNC machine tool tool changer impact absorption
- Packaging machinery feed system end damping
- Robotic end effector vibration control
- Elevator car buffer systems
- Stamping press overtravel protection
Installation guidelines:
Mount using M12 bolts with 25-30 N·m torque. Adjust damping force by rotating the
hex socket (2mm Allen key required) - clockwise increases resistance. Perform
run-in with 50% impact energy for 200 cycles before full operation. Maintain
vertical installation tolerance within ±2°.
