A precision rotary clamping solution featuring dual-action torque amplification and anti-vibration design. The QCKL series incorporates a unique cam mechanism that converts linear motion into 90° rotation with self-locking capability. Enhanced with wear-resistant guide bushings and hardened steel shafts for >500,000 cycle durability. Includes built-in magnetic sensor slots (M5x0.8 threaded) for position feedback devices.
- CNC machine tool fixture locking systems
- Automated welding jig positioning
- Robotic arm end-effector clamping
- PCB assembly line component retention
- Medical device manufacturing tooling
Operation tip:
For optimal performance, maintain air supply dew point below -10℃ and
use ISO 8573-1 Class 3 filtered air. Apply Molykote G-5007 grease annually
to rotation mechanism. Avoid side-load forces exceeding 30N during clamping.
