The AirTAC AirTAC SDA32X55B 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 SDA32X55B 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. Driven by a 32 mm bore and 55 mm stroke, this thin-profile actuator utilizes a short riveted body assembly that drastically reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery with tight spatial footprints.
This specific SKU features a male M10x1.25 piston rod thread for robust mechanical coupling to your load. The bore is hard-anodized for longevity, and the unit relies on a fixed NBR bumper at each end to decelerate the stroke. Because this configuration omits the -S magnet code, it cannot directly host AirTAC reed or electronic switches.

Secures aluminum workpieces in a CNC machining center, utilizing the 402.1 N extend force to hold parts firmly against a stop during milling operations.
Drives a mechanical arm to fold corrugated box flaps at 30-500 mm/s, where the compact riveted body conserves valuable space on a high-speed packaging line.
Actuates a routing gate on a logistics conveyor, using the male M10x1.25 rod end to push parcels efficiently without consuming excessive axial frame depth.
When sizing this 32 mm bore actuator, evaluate your force margins carefully. Stepping down, the SDA25 provides 245.4 N of push at 0.5 MPa, whereas stepping up to the SDA40 yields 628.3 N at the same pressure. Based on the 402.1 N output, 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 standard SDA cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift, as the fixed rubber bumper only decelerates near the end of travel and acts as neither a lock nor a brake. For suspended loads, an external rod lock or pilot-operated check valve is required. To order, confirm the 32 mm bore, 55 mm stroke, PT1/8 port, male M10x1.25 rod thread, and the absence of a sensor magnet.
Quick checklist
This 32 mm bore double-acting cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, it outputs 563 N push and 483.8 N pull. The theoretical maximum push force is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the -S option, meaning it has no internal piston magnet and cannot trigger AirTAC reed or electronic switches. You would need the SDA32X55BS variant for position sensing. Additionally, end-stop deceleration is handled solely by a fixed NBR bumper, which is not an adjustable air cushion.
