The AirTAC AirTAC SDA16X75B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 75mm 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 SDA16X75B is a double-acting, single-rod compact cylinder engineered for tight machinery spaces. Its riveted assembly minimizes axial mounting depth while delivering 100.5 N of push force at 0.5 MPa. This specific SKU features a male M5x0.8 piston rod thread for direct load coupling and operates at speeds between 30-500 mm/s.
Because the 75 mm stroke exceeds the 60 mm maximum standard stroke for this 16 mm bore, this unit is a non-standard, made-to-order configuration. The bore is hard-anodized for longevity, and end-stops rely on fixed NBR bumpers rather than adjustable cushions. Note that this variant lacks a piston magnet, so position sensing is not supported without the -S option.

Provides the 100.5 N push required to actuate the cutting head feed on small circuit board routing machines, utilizing the male M5x0.8 thread for precise tool mounting.
Drives a 75 mm stroke to move liquid dispensing valves between reagent stations, where the short body footprint conserves valuable benchtop space.
Actuates folding arms on compact packaging lines, handling light cardboard materials where a 5.1 kg vertical lift margin is sufficient for the mechanism.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA12 reduces the push force 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 output, the safe working load is approximately 60 N, translating to a vertical lift capacity of about 5.1 kg with a 2:1 safety margin.
Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your application requires load holding, you must integrate an external rod lock or a pilot-operated check valve. Confirm your ordering essentials: 16 mm bore, 75 mm non-standard stroke, M5x0.8 port, male rod thread, and no magnet.
Quick checklist
This 16 mm bore double-acting cylinder provides a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa. At 0.7 MPa, the push increases to 140.7 N. The theoretical maximum push is 21 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need to specify the -S option to enable sensing. Additionally, end-of-travel deceleration is handled by fixed NBR bumpers, not an adjustable air cushion, so external shock absorbers may be needed for high-speed operations.
