- Automotive welding jig quick-change systems
- Electronics PCB press-fitting mechanisms
- Packaging machine mold clamping
- Robotic end-effector tool changers
Installation guidelines:
Lubricate with ISO VG32 hydraulic oil before initial use.
Maintain 0.3mm minimum clearance between clamp arm and workpiece surface.
Use clean dry air with 5-40μm filtration. For vertical mounting,
install air inlet port downward to prevent debris accumulation.
