- Automotive welding fixture positioning
- Foundry mold clamping mechanisms
- Palletizing robot end-effector actuators
- Paper roll handling in printing machinery
 Maintenance tip: 
            Perform cushion adjustment at 50% lower than maximum operating pressure during commissioning. 
            Use 190-220 N·m torque for mounting bolts. Avoid side load exceeding 350N.
