High-precision rotary clamping cylinder featuring dual-action torque control and precision ground gears. The hardened stainless steel shaft and dual ball bearing structure ensure smooth 90° rotation even under side loads. Includes wear-compensation mechanism for extended service life. Requires ISO 8573-1:2010 Class 3 compressed air.
- Automated welding fixture positioning
- CNC machine tool workpiece clamping
- Robotic end-effector rotation mechanisms
- High-temperature molding machine core pulling
- Precision optical component assembly stations
Operation note:
Always apply AirTAC PG-7 grease during maintenance. For continuous rotation applications,
limit cycle rate to ≤15 CPM. Use M6x12 (8.8 grade) mounting bolts torqued to 8.5 N·m.
Critical parameters:
Maintain air dryness (pressure dew point ≥3℃ below ambient). Maximum lateral load capacity:
450N at piston rod end. Lubricate every 500,000 cycles under normal operation.
