The AirTAC AirTAC SDA63X120SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 120mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA63X120SB is a double-acting, single-rod compact cylinder engineered for tight axial mounting spaces. Utilizing a short riveted body assembly, it drastically reduces overall machine footprint compared to conventional round-body units. At 0.5 MPa, this 63 mm bore generates 1558.6 N of push force and 1401.5 N of pull force, operating efficiently at speeds between 30-500 mm/s.
This specific configuration includes an integrated piston magnet for direct compatibility with AirTAC magnetic reed or electronic switches. The rod end features a male M18x1.5 thread, providing a robust coupling interface for your load. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles.

Provides the 1558.6 N push force required to fold heavy corrugated cardboard flaps on high-speed packaging lines without stalling.
Shifts heavy wooden pallets laterally on a conveyor using the 120 mm stroke and male M18x1.5 threaded rod for secure linkage.
Knocks out dense plastic parts from injection molds, utilizing the compact riveted body to fit within tight machine clearances.
When sizing this model, consider stepping down to the SDA50, which yields 981.7 N of push at 0.5 MPa, or stepping up to the SDA80 for 2513.3 N if your application demands greater thrust. For the 1558.6 N rating at 0.5 MPa, a safe working load is approximately 935 N, translating to a vertical lift capacity of about 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 120 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required magnetic switch option. Note that a standard cylinder drifts when air pressure is lost; utilize an external rod lock or pilot-operated check valve if the load must be held in place.
Quick checklist
This 63 mm bore cylinder delivers 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, the SDA series relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits. It is not an adjustable air cushion, nor does it function as a braking lock. For high-speed operations, you should add external shock absorbers or reduce the approach speed.
