The AirTAC AirTAC SDA32X50SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 50mm 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 SDA32X50SBH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. Its riveted body assembly significantly reduces mounting depth compared to round-body units, delivering a push force of 402.1 N at 0.5 MPa. This specific configuration includes a male M10x1.25 piston rod, a built-in magnet for position sensing, and high-temperature fluororubber (FKM) seals.
A fixed NBR bumper at each end manages end-stop deceleration, though it is not an adjustable air cushion. For rapid cycling, an external shock absorber is advised. The hard-anodized 32 mm bore operates at speeds between 30-500 mm/s, and the integrated magnet supports AirTAC reed or electronic switches along the body grooves.

Secures aluminum workpieces in CNC machining centers using the male M10 rod end, while FKM seals resist synthetic cutting fluid mist.
Drives a heated sealing jaw on a vertical form-fill-seal machine, where the compact depth saves footprint and the magnet tracks jaw position.
Pushes populated printed circuit boards out of an assembly fixture with a controlled 50 mm motion, relying on the 402.1 N extend force.
This 32 mm bore generates 402.1 N of push force at 0.5 MPa, offering a safe working load around 241 N (roughly 60% capacity) and a vertical lift capability of about 20.5 kg with a 2:1 safety margin. If your application requires less force, the SDA25 provides 245.4 N; for heavier demands, the SDA40 steps up to 628.3 N.
Remember that a standard cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only slows the piston near stroke end and does not act as a lock. To hold a load securely without live pressure, incorporate an external rod lock or a pilot-operated check valve. When ordering, confirm the 50 mm stroke, PT1/8 port, male M10x1.25 rod thread, magnet, and FKM seal options.
Quick checklist
This 32 mm bore cylinder uses a PT1/8 port. It generates a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke ends and is not a braking mechanism. To maintain position without live pressure, you must add an external rod lock or a pilot-operated check valve.
