The AirTAC AirTAC SDA20X130B Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 130mm stroke, M5×0.8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA20X130B is a double-acting, single-rod compact cylinder engineered to deliver 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. Its riveted assembly joins the barrel, rear cover, and piston into a highly space-efficient unit, drastically reducing axial mounting depth compared to conventional round-body designs. This specific configuration includes a male M6x1.0 threaded piston rod end for secure mechanical coupling to your load.
Because the 130 mm stroke exceeds the 100 mm standard maximum for this 20 mm bore, this unit is a non-standard, made-to-order configuration. The bore is hard-anodized and relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Operating speeds span 30-500 mm/s within a 0.15-1.0 MPa pressure range.

Pushes light cardboard cartons on a logistics sorting line using a safe working load of 94 N, fitting neatly into tight conveyor frame gaps.
Utilizes the 130 mm extended reach and male M6x1.0 rod to gently eject populated circuit boards from an SMT testing fixture.
Actuates a pivoting tensioner on a vertical form-fill-seal machine, applying a consistent 131.9 N pull force to maintain web tension.
When sizing this actuator, evaluate your force requirements against its 157.1 N push at 0.5 MPa, which yields a safe working load of roughly 94 N (about 8 kg vertical lift with a 2:1 margin). If your application demands less force, stepping down to the SDA16 provides 100.5 N, while moving up to the SDA25 increases capability to 245.4 N. Note that a plain SDA body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For secure load holding, integrate an external rod lock or a pilot-operated check valve.
This SKU is specified with a 20 mm bore, 130 mm stroke, and an M5x0.8 port. It includes the -B option, giving you a male M6x1.0 piston rod thread instead of the default female M4x0.7. It lacks the -S magnet option, so it cannot support reed or electronic switches.
Quick checklist
At 0.5 MPa, the push force is 157.1 N and the pull force is 131.9 N. At 0.7 MPa, the push force is 219.9 N and the pull force is 184.7 N. The theoretical maximum push force is 32 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger reed or electronic switches. Additionally, because the 130 mm stroke exceeds the 100 mm standard maximum for a 20 mm bore, it is a made-to-order item with a fixed NBR bumper that cannot be field-adjusted for cushioning.
