The AirTAC AirTAC SDA32X90S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 90mm 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 SDA32X90S 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 merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for low-friction cycling across the 30-500 mm/s speed range.
This specific configuration includes a 90 mm stroke and a built-in piston magnet (denoted by the S suffix) for position detection via AirTAC reed or electronic switches seated in the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact wear.

Pushes cartons off a sorting line using the 90 mm stroke, relying on the 402.1 N push force at 0.5 MPa to handle heavy cardboard boxes without bouncing.
Shuttle tooling into a machining center, where the compact riveted body minimizes Z-axis footprint and the PT1/8 port keeps pneumatic lines neatly routed.
Folds corrugated flaps on an automated packing line, using the fixed NBR bumper to absorb the gentle end-of-stroke impact without marking the packaging material.
Selecting this 32 mm bore yields a safe working load of roughly 241 N (about 60% of its 402.1 N push capacity at 0.5 MPa), translating to a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA25 provides 245.4 N at 0.5 MPa; conversely, upgrading to the SDA40 increases output to 628.3 N at 0.5 MPa. Keep in mind that a standard double-acting actuator will drift if air pressure drops or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the rod—implement a pilot-operated check valve or external rod lock if you must hold a suspended load.
When ordering, confirm the 32 mm bore, 90 mm stroke, PT1/8 port, female M6x1.0 rod-end thread (or male M10x1.25 if specified), and the -S magnet option for switch readiness.
Quick checklist
This 32 mm bore double-acting cylinder provides 402.1 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and 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 rod near the stroke end and does not function as a braking lock. To suspend a load safely, you must add an external rod lock or a pilot-operated check valve.
