The AirTAC AirTAC SDA32X100S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 100mm 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 SDA32X100S 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 significantly reduces axial mounting depth compared to round-body units, making it highly effective for tight machine footprints. The 32 mm bore features a hard-anodized inner wall and a 12 mm piston rod.
Because this unit includes the S option, it contains a built-in piston magnet for position sensing via AirTAC reed or electronic switches mounted in the body grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators must control approach speeds to manage impact energy. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.

Pushes small to medium parcels off a sorting line using the 100 mm stroke, relying on the 402.1 N extend force to overcome box friction.
Actuates a short tool-release mechanism in a machining center where axial depth is restricted, utilizing the built-in magnet to confirm retraction.
Drives a folding arm to close corrugated box flaps, taking advantage of the compact riveted body to fit within tight conveyor framing.
When sizing this actuator, evaluate your neighbours: the SDA25 provides 245.4 N push at 0.5 MPa for lighter duties, while the SDA40 steps up to 628.3 N for heavier cycles. For the SDA32X100S specifically, the safe working load is roughly 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of approximately 20.5 kg with a 2:1 safety margin. To finalize your order, confirm the 32 mm bore, 100 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the required S magnet code.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only reduces impact near the stroke endpoints and does not function as a mechanical lock. If your application demands position holding without live pressure, integrate 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, push is 563 N and pull is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa, with a proof pressure of 1.5 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. For high-speed or high-energy cycles, you should slow the approach speed or add an external shock absorber. Additionally, the S option provides a magnet for AirTAC reed or electronic switches.
