The AirTAC AirTAC SDA32X120BH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 120mm 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 SDA32X120BH 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 short riveted body significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. This specific configuration includes a male M10x1.25 threaded piston rod end for secure mechanical load coupling, alongside an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
Built with a hard-anodized 32 mm bore and a 12 mm piston rod, this unit operates at speeds between 30-500 mm/s. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; position sensing requires external methods or the -S variant.

Secures aluminum workpieces in a CNC machining center using the 402.1 N extend force, while the FKM seals resist exposure to synthetic cutting fluids.
Cycles empty pallets into a packaging line over the 120 mm stroke, where the male M10x1.25 rod threads directly into the pusher assembly.
Opens and closes high-temperature sterilization oven doors, leveraging the FKM seal option to maintain integrity in elevated thermal environments.
When sizing this model, evaluate your force requirements carefully. Stepping down to the SDA25 provides 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 yields 628.3 N at the same pressure. For the SDA32X120BH, the 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. Ensure you specify the PT1/8 port, the 120 mm stroke, the male M10x1.25 rod thread, and the FKM seal when ordering.
Keep in mind that a standard double-acting cylinder does not inherently hold its position if air pressure is lost or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the load near the stroke end rather than locking it. If your application demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 32 mm bore cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and operational speeds of 30-500 mm/s.
No, this specific SKU does not include the -S magnet option, so it cannot host AirTAC reed or electronic switches in the body grooves. You would need to specify the -S variant for internal magnetic position sensing. Additionally, it uses a fixed NBR bumper for end-stop deceleration, not an adjustable air cushion.
