The AirTAC AirTAC SDA32X55 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 SDA32X55 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 into an ultra-short unit, significantly reducing axial footprint compared to conventional round-body designs. The bore is hard-anodized and utilizes a two-way piston seal for reliable pneumatic performance.
This specific configuration features a 55 mm stroke and a 12 mm piston rod with a female M6x1.0 rod-end thread. End-of-travel deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot host magnetic position sensing without modifying the build.

Provides the 402.1 N push stroke required to fold heavy corrugated cardboard flaps on automated packaging lines without consuming excessive machine depth.
Actuates a routing gate at 30-500 mm/s to redirect parcels weighing up to 20.5 kg between conveyor belts in distribution centers.
Drives a 12 mm rod to seat dowel pins into aluminum housings on an assembly fixture, utilizing the hard-anodized inner bore for consistent alignment.
When sizing this 32 mm bore, consider stepping down to the SDA25 which provides 245.4 N of push at 0.5 MPa for lighter duties, or moving up to the SDA40 which yields 628.3 N at 0.5 MPa for heavier loads. At 0.5 MPa, this SDA32X55 yields a safe working load of roughly 241 N (about 60% of its 402.1 N output) and can vertically lift approximately 20.5 kg with a 2:1 safety margin. Keep in mind that a standard double-acting 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 suspended load securely, integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 32 mm bore, 55 mm stroke, PT1/8 port, female rod thread, and no sensor magnet.
Quick checklist
The SDA32X55 generates 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push at 0.7 MPa. Its theoretical maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not an adjustable air cushion. Additionally, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches; you must select the -S option for position sensing.
