The ACJ3350 features oil viscosity self-compensation technology that automatically adjusts damping force across temperature fluctuations. Its dual-stage buffering mechanism combines progressive orifice control with precision metering pins, delivering smooth deceleration for heavy inertial loads. The hexagonal adjustment collar allows torque wrench calibration (recommended 2-3 N·m).

- Automated warehouse stacker cranes
- Stamping press ram deceleration
- Robotic palletizing arm end-effectors
- CNC machine tool automatic door mechanisms
Installation protocol:
Pre-lubricate shaft with ISO VG68 way oil before initial operation.
Perform 10-15 "break-in cycles" at 50% rated load after installation.
Maintain 20mm clearance behind buffer for heat dissipation.
