The AirTAC AirTAC SDA32X150SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 150mm 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 SDA32X150SB is a double-acting, single-rod compact cylinder engineered with a riveted body to minimize axial footprint. It provides 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. This specific configuration includes a built-in piston magnet for position sensing and a male M10x1.25 threaded rod end for secure load coupling.
Because the 150 mm stroke exceeds the 130 mm maximum standard stroke for this 32 mm bore, this unit is a non-standard, made-to-order configuration. End-of-travel deceleration is managed by a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s, and the body features integrated grooves for mounting AirTAC reed or electronic switches.

Pushes cartons between sorting lanes on a logistics conveyor belt using a 150 mm extension stroke.
Closes the upper jaw of a flow-wrap packaging machine, utilizing the 402.1 N push force to seal product film.
Actuates the sliding inner doors of a small freight elevator, taking advantage of the compact body depth.
When sizing this actuator, evaluate stepping down to the SDA25 which yields 245.4 N push at 0.5 MPa, or moving up to the SDA40 which provides 628.3 N push at 0.5 MPa. For the current 32 mm bore, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. To order, confirm the 32 mm bore, 150 mm non-standard stroke, PT1/8 port, the required -S magnet, and the -B male M10x1.25 rod thread.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the piston near stroke end without locking it. If your application must hold a load without live pressure, install an external rod lock or a 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, the push force is 563 N and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, this actuator uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
