- Automotive welding fixture stations
- Precision grinding machine jigs
- PCB drilling equipment clamping
- Robotic arm end-effector tool changing
Installation guidelines:
Apply 32# hydraulic oil for initial lubrication. Maintain 0.3–0.6MPa operating pressure for optimal cam engagement.
Avoid side load exceeding 50N during rotary motion. Align within 0.2mm perpendicularity tolerance during mounting.
