The AirTAC AirTAC SDA32X120S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 120mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X120S is a double-acting, single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly significantly shortens axial mounting depth compared to round-body units, saving valuable machine footprint. The 32 mm bore features a hard-anodized inner wall and a 12 mm piston rod.
Equipped with a built-in piston magnet (-S), this unit supports position detection via an AirTAC reed or electronic switch housed in the body grooves. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy 120 mm stroke impacts.

This 32 mm bore generates 402.1 N push at 0.5 MPa, sitting neatly between the SDA25 (245.4 N) and the SDA40 (628.3 N) to help you scale force precisely. A practical safe working load is roughly 241 N (60% of the 0.5 MPa figure), yielding a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. To finalize your order, confirm the 120 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the required -S magnet for sensing.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load. If your application must hold position without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, this model uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. For high-speed or high-energy impacts over the 120 mm travel, you should slow the approach speed or install an external shock absorber.
