The AirTAC AirTAC SDA32X55SB Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 55mm 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 SDA32X55SB 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, making it ideal for machinery where a standard round-body unit simply will not fit. The 32 mm bore features a hard-anodized inner wall and operates on filtered air at 30-500 mm/s.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a -B male M10x1.25 threaded rod end for secure mechanical load coupling. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact wear.

Selecting this 32 mm bore provides a practical middle ground: it uprates the 245.4 N push of the SDA25 while avoiding the bulk of the SDA40 which pushes 628.3 N at 0.5 MPa. For your 55 mm stroke, the PT1/8 port and 12 mm rod are fixed by the bore. When sizing payloads, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin.
Because this is a double-acting air cylinder, it will not hold a load if air pressure drops or the control valve is centered—the piston will drift. If your application requires strict position holding on loss of pressure, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 32 mm bore, 55 mm stroke, S magnet, and B male rod thread.
Quick checklist
This double-acting 32 mm bore 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 force is 82 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so high-speed applications may need external shock absorption. The built-in -S magnet allows you to mount AirTAC reed or electronic switches directly into the body grooves for end-position detection.
