Engineered for heavy-duty industrial applications requiring precision deceleration control. Features automatic viscosity compensation that maintains consistent damping performance across temperature fluctuations (-10℃ to +80℃). The progressive damping curve prevents hard stops while minimizing rebound, with a unique dual-chamber design that separates air and oil to prevent foaming.
- High-speed robotic arm end effectors
- Stamping press ram deceleration systems
- Automated warehouse shuttle brakes
- CNC machine tool door dampers
- Packaging line conveyor impact absorption
Installation protocol:
Mount with M12×1.75 mounting bolts (35 Nm torque). Requires 0.5mm minimum alignment tolerance between piston rod and impact surface. Perform initial 50-cycle break-in period before final adjustment. Relubricate every 50,000 cycles using specified oil grade.
