The AirTAC AirTAC SDA32X140SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 140mm 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 SDA32X140SB is a double-acting, single-rod compact cylinder engineered with a short riveted body to minimize axial mounting depth in tight machinery footprints. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. This specific configuration includes a built-in piston magnet for position sensing and a male M10x1.25 threaded rod end for secure load coupling.
Because the 140 mm stroke exceeds the 32 mm bore's 130 mm maximum standard length, this unit is a non-standard, made-to-order configuration. The bore is hard-anodized, and end-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions. For high kinetic energy loads, an external shock absorber should be specified to prevent impact damage.

Actuates a routing flap on a logistics sorting line, utilizing the 140 mm travel to push parcels cleanly between adjacent conveyor belts.
Drives a secondary positioning pin on a machining center tool changer, where the male M10x1.25 rod end secures the linkage and the short body saves axial space.
Folds corrugated box side flaps prior to tape sealing, using the 402.1 N extend force to overcome cardboard resistance reliably.
When sizing this actuator, evaluate stepping down to an SDA25 (245.4 N push @0.5 MPa) for lighter duties, or up to an SDA40 (628.3 N push @0.5 MPa) if your application demands greater thrust. Based on the 402.1 N push figure at 0.5 MPa, the computed safe working load is roughly 241 N (about 60% capacity), translating to a vertical lift capability of approximately 20.5 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load safely without live pressure, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 32 mm bore, 140 mm non-standard stroke, PT1/8 port, built-in magnet (S), and male M10x1.25 rod thread (B).
Quick checklist
This 32 mm bore double-acting cylinder provides a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 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 speed range of 30-500 mm/s.
It relies on fixed NBR bumpers to decelerate the piston at stroke ends, which are not field-adjustable; for high-speed approaches, consider external shock absorbers. The built-in magnet (-S) allows you to mount AirTAC reed or electronic switches directly into the body grooves for precise position detection.
