- Automated welding jig positioning
- Pallet clamping in assembly lines
- Robotic end-effector tool changers
- Precision mold holding devices
Operation tip:
For optimal performance, maintain air supply dew point below -15℃ and install
a 5μm filter. Use speed controllers (ASC-06) to adjust clamping velocity.
Avoid side loads exceeding 30N on the rod end.
