The AirTAC AirTAC SDA16X40B 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 SDA16X40B is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial length where standard round bodies fail to fit, yielding a push force of 100.5 N and a pull force of 86.4 N at 0.5 MPa.
This specific SKU features a male M5x0.8 threaded piston rod for direct load coupling, paired with an M5x0.8 air port. End-of-travel deceleration relies on fixed NBR bumpers rather than adjustable cushions, meaning high-speed cycles may require external shock absorbers. Since this configuration lacks the -S magnet, position sensing is not supported.

Actuates a routing head to singulate printed circuit boards, utilizing the 40 mm stroke and 100.5 N force to maintain precise positioning within a compact electronics assembly fixture.
Drives the upper heat platen in a small-scale blister packaging machine, where the short riveted body conserves vertical space and the male M5x0.8 rod securely mounts the heating element.
Moves a micro-valve for chemical reagent dispensing, leveraging the 86.4 N retract force at 0.5 MPa to reset the mechanism reliably in dense laboratory equipment layouts.
When sizing this actuator, compare its 100.5 N push at 0.5 MPa against adjacent bores: the SDA12 offers 56.5 N for lighter duties, while the SDA20 steps up to 157.1 N for heavier loads. A practical safe working load is approximately 60 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 5.1 kg with a 2:1 safety margin. To finalize your order, confirm the 16 mm bore, 40 mm stroke, M5x0.8 port, and the male M5x0.8 rod thread.
Keep in mind that a standard double-acting 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; suspended or gravity-loaded applications require an external rod lock or pilot-operated check valve.
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. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No. This specific SKU lacks the -S piston magnet, so it cannot accept reed or electronic switches. Additionally, SDA series cylinders use fixed NBR bumpers at each end for deceleration rather than adjustable air cushions; you must slow the approach externally or add shock absorbers for high-energy loads.
