The AirTAC AirTAC SDA32X30SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 30mm 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 SDA32X30SB 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 body assembly significantly reduces axial mounting depth, making it highly effective for machinery where a standard round-body unit would simply not fit. The hard-anodized 32 mm bore operates at speeds between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet (-S) for position sensing via AirTAC reed or electronic switches, and a male M10x1.25 threaded rod end (-B) for secure mechanical load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should reduce approach speeds or utilize external shock absorbers for high-energy loads.

Secures aluminum workpieces in a CNC machining center using the 402.1 N extend force, while the 30 mm stroke provides rapid actuation within a tight tooling envelope.
Drives a mechanical arm to tuck end flaps on a packaging line, utilizing the male M10x1.25 rod end for a rigid connection and the built-in magnet to verify fold completion.
Actuates a routing paddle to push selected parcels off a main conveyor belt, relying on the short riveted body to fit within the narrow transfer gap.
When sizing this unit, evaluate your force requirements carefully. Stepping down to the SDA25 provides 245.4 N of push at 0.5 MPa, while moving up to the SDA40 yields 628.3 N. For the SDA32X30SB, the safe working load is approximately 241 N (about 60% of the 402.1 N capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 30 mm stroke, PT1/8 port, male M10x1.25 rod thread, and the required magnetic sensor option.
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. The theoretical maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operating temperature spans -20 to +70 C.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake; high-speed applications may need external shock absorbers. Because it includes the -S magnet, you can mount AirTAC reed or electronic switches directly into the body grooves for position detection.
