The 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. 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.
