The AirTAC AirTAC SDA32X20SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 20mm 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 SDA32X20SB 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 body design drastically reduces axial mounting depth, making it the superior choice for machinery where a standard round-body unit simply cannot fit. The hard-anodized 32 mm bore operates at speeds between 30 and 500 mm/s.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M10x1.25 threaded piston rod (-B) for secure load coupling. End-of-stroke 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 damage.

Actuates the cutting head alignment gate on an electronics assembly line, utilizing the 20 mm stroke and male M10x1.25 rod to securely lock the toolhead bracket in place.
Tucks the side flaps of corrugated shipping boxes at high speed, where the short riveted body saves valuable axial space within the tight conveyor frame.
Triggers a secondary parts ejector pin on a 50-ton press, using the integrated magnet to confirm retraction before the mold closes.
Selecting this 32 mm bore provides a safe working load of roughly 241 N (about 60% of the 402.1 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, the SDA25 offers 245.4 N at 0.5 MPa; stepping up to the SDA40 yields 628.3 N at 0.5 MPa. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary for strict position holding.
When ordering, confirm the 32 mm bore, 20 mm stroke, PT1/8 port size, the required magnetic sensing option, and the male M10x1.25 rod thread to ensure seamless integration.
Quick checklist
At 0.5 MPa, this double-acting 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. The theoretical maximum push force is 82 kgf at 1.0 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits, which is not an adjustable air cushion. Furthermore, it does not hold its position if air pressure drops; an external rod lock or pilot-operated check valve is required for fail-safe load holding.
