The AirTAC AirTAC SDA20X100 Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 100mm 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 SDA20X100 is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It produces a 157.1 N push and 131.9 N pull at 0.5 MPa, operating within a 30-500 mm/s speed range. The hard-anodized aluminum bore and two-way piston seal ensure reliable service across a -20 to +70 C temperature window.
Featuring a 100 mm stroke and an 8 mm piston rod, this unit minimizes axial mounting depth via its riveted body construction. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.

Actuates a routing flap on a packaging conveyor to sort small cartons, utilizing the 100 mm stroke to clear the belt path completely.
Pushes processed test tubes out of a centrifuge carousel, where the compact riveted body fits within the dense laboratory equipment chassis.
Extends a cutting blade guide across an electronics assembly line, applying steady force without overwhelming delicate fiberglass substrates.
When sizing this actuator, stepping down to the SDA16 yields 100.5 N of push force at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N. For this 20 mm bore, a safe working load is approximately 94 N (about 60% of the 157.1 N figure), translating to a vertical lift capacity of roughly 8 kg with a 2:1 safety margin. To finalize your order, confirm the 100 mm stroke, M5x0.8 port, female M4x0.7 rod thread, and the absence of a sensor magnet.
Because a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, this model will not hold a load securely mid-stroke. The fixed rubber bumper only softens the impact near the end caps and does not act as a mechanical brake. If your application requires strict position holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20 mm bore cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, increasing to 219.9 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum push force is 32 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the SDA20X100S variant to enable position sensing. Additionally, end-stop deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
