Airtac HRQ Rotary Cylinder HRQ20A
2. Dual-cylinder design enables double output force;
3. High-precision machined worktable facilitates easy load mounting and precise positioning;
4. Central through-hole allows integrated piping configuration;
5. Mounting holes provided on both sides (models 10-200) or base surface (models 2-7) for flexible installation;
6. Dual cushioning options: adjustable screw-type cushioning or hydraulic shock absorber. Hydraulic variant delivers 3-5 times greater damping energy for superior buffering performance.
*Note: HRQ2, 3, and 7 models feature screw-type cushioning only, without hydraulic shock absorber option. Category: Rotary Cylinders | Brand: AirTAC | Series: HRQ

High-precision rotary actuator featuring helical gear engagement for smooth angular positioning. The hardened stainless steel shaft and dual-bearing design ensure minimal backlash (±0.2° repeatability). Optimized for cleanroom-compatible applications with <0.1mg/m³ particle emission. Requires 5μm filtered air with dew point -20℃ below ambient.
- PCB board flipping mechanisms in SMT lines
- 90° workpiece orientation changers
- Valve actuation in semiconductor wafer handling
- Camera module rotation in optical inspection systems
- Pallet indexing in pharmaceutical packaging
Installation tip:
Use dynamic alignment during mounting - maximum allowable
lateral shaft load 15N. For continuous rotation applications,
limit duty cycle to 70% with 30-second rest intervals.
