Airtac HRQ Rotary Cylinder HRQ70
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
