The AirTAC AirTAC SDA16X40SB Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 40mm 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 SDA16X40SB is a double-acting single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth compared to conventional round-body units. Delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa, it handles light-duty positioning with a 6 mm piston rod.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M5x0.8 threaded rod end (-B) for secure mechanical load coupling. End-stops rely on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption to prevent impact wear.

Provides the 100.5 N extension stroke needed to push singulated circuit boards out of routing fixtures without damaging delicate surface-mount components.
Cycles at 30-500 mm/s to fold cardboard tuck flaps on pharmaceutical blister packaging lines, fitting neatly into narrow transfer carriage gaps.
Actuates precision metering valves for reagent dispensing, using the male M5x0.8 rod end to drive a precise 40 mm plunger displacement.
When sizing this 16 mm bore actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the push output to 56.5 N at 0.5 MPa, whereas stepping up to the SDA20 increases it to 157.1 N. Based on the 100.5 N push rating, the safe working load is approximately 60 N, yielding a vertical lift capacity of about 5.1 kg with a 2:1 safety margin. To finalize your order, confirm the 16 mm bore, 40 mm stroke, M5x0.8 air port, male M5x0.8 rod thread, and the required magnetic sensor option. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; if your process demands strict position holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and functions in ambient temperatures from -20 to +70 C.
No, the SDA16X40SB uses a fixed NBR bumper at each end to decelerate the piston near stroke termination. It is not an adjustable air cushion. For high kinetic energy loads, you should slow the approach speed or install an external shock absorber. The built-in magnet allows tracking via a reed or electronic switch, but the bumper does not lock the rod in place if air pressure drops.
