The AirTAC AirTAC SDA32X25B Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 25mm 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 SDA32X25B 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 profile, drastically reducing axial mounting depth where a conventional round-body unit would be too bulky. The 32 mm bore features a hard-anodized inner wall and operates on a PT1/8 port.
This specific SKU includes a male M10x1.25 thread on the 12 mm piston rod, offering a robust external coupling point for your load. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Secures aluminum workpieces in a CNC machining center using the male M10x1.25 rod end, providing 402.1 N of clamping force without extending the machine footprint.
Actuates folding mechanisms on a packaging line where the short 25 mm stroke and fixed NBR bumpers rapidly position corrugated cardboard flaps for sealing.
Pushes singulated printed circuit boards out of a depaneling router, utilizing the space-saving riveted body to fit within dense electronics manufacturing machinery.
When sizing this 32 mm bore actuator, consider stepping down to the SDA25 if your application requires less force, which provides 245.4 N of push at 0.5 MPa. Conversely, if your load demands more power, the SDA40 offers 628.3 N at the same pressure. For the SDA32X25B, 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. Keep in mind this compact unit does not hold its position if air pressure drops or the valve is centered; the piston will drift, and an external rod lock or pilot-operated check valve is necessary for secure load holding. Confirm your ordering essentials: 32 mm bore, 25 mm stroke, PT1/8 port, male M10x1.25 rod thread, and no sensor magnet.
Quick checklist
This double-acting 32 mm bore cylinder generates 402.1 N push and 345.6 N pull at 0.5 MPa, and 563 N push at 0.7 MPa. The theoretical maximum push force is 82 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No adjustable air cushion is available; end-stroke deceleration is handled solely by a fixed NBR bumper, so you should slow the approach or add an external shock absorber for high-energy loads. Additionally, this specific SKU lacks the -S piston magnet, meaning it cannot support AirTAC reed or electronic switches without changing to an -S variant.
