Airtac QDKR Pivoting Clamping Cylinder QDKR20X5-S-U
1. Achieves rotational motion at identical elevation level with zero rotational stroke, offering enhanced spatial efficiency compared to QCK series in confined environments;
2. Versatile mounting configurations with optional front cover boss-type or flat-type designs;
3. Dual-pin rotational guide groove mechanism ensures smooth operation and exceptional repeat positioning accuracy (±0.5°);
4. Integrated sensor mounting grooves on cylinder periphery enable direct installation without auxiliary accessories.

Precision rotary clamping cylinder with integrated wedge mechanism for 90° rotational locking. Features anti-vibration design with hardened guide rods and wear-resistant bushings. The corrosion-resistant aluminum alloy body includes a status detection slot for sensor mounting. Requires filtered air (40μm) with ISO VG32 hydraulic oil mist lubrication.
- CNC machine tool fixture positioning
- Automated welding jig locking systems
- PCB assembly line component retention
- Robotic end-effector tool changing mechanisms
- Medical device manufacturing alignment fixtures
Operation tip:
Maintain 0.3-0.6 MPa working pressure for optimal torque-to-wear ratio.
Lubricate pivot points monthly with MIL-PRF-6085 grease. Avoid side loads exceeding 50N
during clamping operations.
