Airtac QDKR Pivoting Clamping Cylinder QDKR40X5-S
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.

High-precision rotary clamping cylinder combining linear thrust and angular displacement. Features dual-action self-locking mechanism for secure positioning. The S-series variant includes shock-absorbing pads and enhanced dust resistance, optimized for high-cycle applications. Requires 5μm filtered compressed air with ISO VG32 lubricant.
- Automated fixture systems in CNC machining centers
- Workpiece positioning in robotic welding cells
- Pallet locking mechanisms for assembly lines
- 90° indexing in semiconductor handling equipment
- Clamping devices for injection molding machines
Operation note:
Always maintain air supply during clamping phase. For vertical installations,
use counterbalance valves to prevent unintended rotation. Lubricate pivot points
every 50,000 cycles using specified grease (AIRTAC LG-500).
Critical parameters:
- Max lateral load: 150N (perpendicular to rod axis)
- Do NOT exceed 100,000 cycles/month without maintenance
- Align workpieces within ±0.5° of rotation axis
