Industrial-grade shock absorber featuring automatic viscosity compensation technology that maintains consistent damping performance across temperature variations. The twin-chamber design prevents oil leakage during high-frequency operation (up to 150 cycles/min). Integrated wear indicator window allows visual inspection of buffer status without disassembly.
- Automated assembly line stopper mechanisms
- CNC machine tool axis end dampers
- Packaging machine feed carriage deceleration
- Robotic arm end effector vibration control
- Elevator car overspeed protection systems
- Heavy-duty conveyor impact absorption
Installation note:
For optimal performance, align impact direction with buffer centerline (±2° tolerance).
Perform initial 50 "break-in" cycles at 50% rated load before full operation.
Maintenance-free design - do NOT disassemble for oil refill.
