The AirTAC AirTAC SDA16X50SB Compact Cylinder | 16mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø16mm bore and 50mm 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 SDA16X50SB is a double-acting single-rod compact cylinder engineered for tight axial spaces. It delivers 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. The riveted body design significantly reduces overall mounting length compared to conventional round-body units, making it highly effective for minimizing machine footprint. Equipped with a 6 mm piston rod, this model utilizes an M5x0.8 air port.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, enabling precise end-of-stroke detection. The -B option denotes a male M5x0.8 threaded piston rod end, providing a straightforward mechanical coupling to your load. End stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should control approach velocity or utilize external shock absorbers for high-energy cycles.

Provides the 100.5 N push stroke needed to eject cut printed circuit boards from a routing fixture without stressing the 6 mm male rod end.
Utilizes its 50 mm travel and fixed NBR bumpers to rapidly fold lightweight corrugated flaps on a packaging line at speeds up to 500 mm/s.
Drives a precision metering valve in a fluid dispensing station, where the compact riveted body saves valuable vertical mounting depth.
When sizing this unit, consider stepping to the SDA12 which provides 56.5 N of push at 0.5 MPa for lighter duties, or moving up to the SDA20 which yields 157.1 N at 0.5 MPa if your payload demands greater thrust. At 0.5 MPa, this 16 mm bore achieves a safe working load of roughly 60 N (about 60% of its rated push) and can vertically lift approximately 5.1 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads without live pressure requires an external rod lock or a pilot-operated check valve. To order, confirm the 16 mm bore, 50 mm stroke, M5x0.8 port, built-in magnet, and male M5x0.8 rod thread.
Quick checklist
This 16 mm bore double-acting cylinder generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 121 N pull at 0.7 MPa. The theoretical maximum push force is 21 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C at speeds of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke end, which is not a field-adjustable air cushion. For high kinetic energy loads, you should add an external shock absorber or slow the approach speed. Additionally, the cylinder does not lock or hold its position if air is lost; the piston will drift, so an external rod lock or pilot-operated check valve is required for fail-safe load holding.
