The AirTAC AirTAC SDA32X75SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 75mm 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 SDA32X75SB 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, making it highly effective for machinery where a standard round-body unit would simply not fit. The hard-anodized 32 mm bore ensures durability while maintaining a swift 30-500 mm/s operating speed.
This specific configuration includes a built-in piston magnet for position detection alongside a male M10x1.25 threaded rod end. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should control the approach speed or utilize external shock absorbers for high-energy loads. Circumferential grooves allow easy mounting of a reed or electronic switch.

Secures aluminum engine blocks on a CNC machining center, utilizing the 402.1 N extend force to hold parts firmly against the table during high-speed milling.
Drives the mechanical arms on a packaging line to tuck corrugated box flaps prior to sealing, taking advantage of the short riveted body to fit within tight conveyor clearances.
Raises lightweight electronic PCB trays between processing tiers, where the male M10x1.25 rod end securely threads into the lifting fork.
When sizing this unit, compare its 402.1 N push at 0.5 MPa against adjacent bores: stepping down to the SDA25 yields 245.4 N, while stepping up to the SDA40 provides 628.3 N. A practical safe working load is roughly 241 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity near 20.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates the stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 75 mm stroke, PT1/8 port, built-in magnet, and male M10x1.25 rod thread.
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, the push increases to 563 N and the pull to 483.8 N. The theoretical maximum push capacity is 82 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycles, you should slow the approach or add an external shock absorber. Because this model includes the -S magnet, you can mount a reed or electronic switch directly into the body grooves for precise position detection.
