The AirTAC AirTAC SDA16X20B Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 20mm 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 SDA16X20B is a double-acting, single-rod compact cylinder engineered for tight axial spaces. It generates 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. The riveted unibody design integrates the barrel, rear cover, and piston to drastically reduce overall length compared to conventional round-body units, making it highly effective for shrinking machine footprints.
This specific configuration includes the -B option, providing a male M5x0.8 threaded piston rod end for secure mechanical load coupling. The 6 mm rod operates within a hard-anodized bore at speeds between 30 and 500 mm/s. End-of-travel deceleration is handled by fixed NBR bumpers rather than adjustable cushions, and this SKU lacks a piston magnet, meaning it cannot directly host AirTAC reed or electronic switches.

Uses the 20 mm stroke and 100.5 N push force to eject freshly routed circuit boards from a routing fixture without damaging delicate surface-mount components.
Employs the male M5x0.8 rod end to drive a short folding arm, tucking end flaps on compact pharmaceutical cartons at high cycling rates within a narrow machine frame.
Provides a compact 20 mm shift to push analytical sample trays into a scanning position, leveraging the short riveted body to fit inside densely packed diagnostic equipment.
When sizing this 16 mm bore actuator, compare its 100.5 N push at 0.5 MPa against adjacent options. Stepping down to the SDA12 yields 56.5 N, while moving up to the SDA20 provides 157.1 N. For practical deployment, this bore safely handles a working load around 60 N (roughly 60% of the 0.5 MPa capacity) and can vertically lift approximately 5.1 kg with a 2:1 safety margin. To order, confirm the 16 mm bore, 20 mm stroke, M5x0.8 port, and the male M5x0.8 rod thread. Note that a standard double-acting cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or pilot-operated check valve, as the internal NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake.
Quick checklist
This double-acting 16 mm bore cylinder provides 100.5 N push and 86.4 N pull at 0.5 MPa, and 140.7 N push at 0.7 MPa. Its theoretical maximum push is 21 kgf at 1.0 MPa. It operates on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
This specific SKU lacks a piston magnet, so it cannot support AirTAC reed or electronic switches. End-stop deceleration is managed by fixed NBR bumpers, which are not adjustable air cushions. For high kinetic energy loads, you should slow the approach speed or install an external shock absorber.
