The AirTAC AirTAC SDA20X110B Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 110mm 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 SDA20X110B is a double-acting, single-rod compact cylinder engineered with a riveted body to minimize axial mounting depth in tight machinery footprints. It delivers a push force of 157.1 N and a pull force of 131.9 N at 0.5 MPa, yielding a safe working load of roughly 94 N or an 8 kg vertical lift with a 2:1 safety margin.
This specific SKU features a male M6x1.0 threaded piston rod for direct load coupling and operates at 30-500 mm/s. Because the 110 mm stroke exceeds the 100 mm maximum standard stroke for this 20 mm bore, it is manufactured as a non-standard, made-to-order unit. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.

Utilizes the 131.9 N retract force to align delicate circuit boards on an SMT pick-and-place conveyor prior to component mounting.
Drives a short mechanical arm to tuck minor flaps on corrugated shipping boxes, taking advantage of the compact body depth in cramped packaging lines.
Adjusts the web path in a flexographic printing press, using the male M6x1.0 rod end to mount a precision dancer roller for tension control.
When sizing this actuator, stepping down to the SDA16 provides 100.5 N of push force at 0.5 MPa, while stepping up to the SDA25 yields 245.4 N. For this 110 mm configuration, the essential ordering parameters are the 20 mm bore, M5x0.8 air port, male M6x1.0 rod end, and the absence of a piston magnet.
Note that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a lock. If your application requires vertical position holding, incorporate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20 mm bore double-acting 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.
No, this specific SKU does not include a piston magnet, so it cannot be used with reed or electronic switches. You would need the SDA20X110BS variant to utilize the body's integrated sensor grooves for position detection.
