The AirTAC AirTAC SDA32X35S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 35mm 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 SDA32X35S 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 to drastically reduce axial mounting depth, solving tight footprint constraints in machinery where longer profile units fail to fit. The 32 mm bore features a hard-anodized inner wall and operates on filtered 40 um air.
Equipped with a built-in piston magnet (the -S option), this unit is ready for AirTAC magnetic reed or electronic solid-state switches seated in the body grooves. End-of-travel impact is managed by a fixed NBR bumper rather than an adjustable cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. The 12 mm rod uses an M6x1.0 female thread end.

Provides the precise 402.1 N push at 0.5 MPa required to eject populated printed circuit boards from a drilling fixture without damaging delicate traces.
Drives a 35 mm stroke arm to fold corrugated cardboard flaps on a continuous packaging line, saving axial depth within the tight conveyor framework.
Pushes small metal pins into aluminum housings on an assembly dial table, utilizing the hard-anodized bore for reliable 30-500 mm/s cycling.
When sizing this actuator, stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N, letting you tune the setup precisely to your payload. For the SDA32X35S, a safe working load is roughly 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity near 20.5 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 32 mm bore, 35 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the required -S magnet.
Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke ends; it does not function as a locking brake. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 32 mm bore double-acting cylinder generates 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 is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
Yes, the -S designation means it has a built-in magnet for AirTAC reed or electronic switches in the body grooves. For high-speed loads, note that it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion; you should add an external shock absorber or slow the approach speed to prevent damage.
