The AirTAC AirTAC SDA32X40S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 40mm 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 SDA32X40S 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 30-500 mm/s.
This specific configuration includes a built-in piston magnet (the -S option) for direct compatibility with AirTAC reed or electronic switches along the body grooves. End-stopping is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles.

Provides the precise 40 mm extension needed to position printed circuit boards under a drill head, utilizing the 402.1 N push force to shift heavy multi-layer panels securely.
Drives a mechanical arm to fold corrugated cardboard flaps at high cycling speeds, relying on the fixed NBR bumper to absorb the impact at the end of each stroke.
Actuates a routing gate on a beverage filling line, where the compact riveted body saves valuable axial space between the narrow conveyor frames.
When sizing this unit, consider stepping down to the SDA25, which provides 245.4 N of push at 0.5 MPa, or moving up to the SDA40, which yields 628.3 N at the same pressure. For the SDA32X40S, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 32 mm bore, 40 mm stroke, PT1/8 port, the required -S magnet, and your choice of female (M6x1.0) or male (M10x1.25) rod thread.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. If your application requires static load holding on loss of pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not act as a locking brake. To maintain position, you must add an external rod lock or a pilot-operated check valve.
