The AirTAC AirTAC SDA16X20SBH 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 SDA16X20SBH is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted assembly joining the barrel, rear cover, and piston yields a minimal footprint, delivering 100.5 N of push force and 86.4 N of pull force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S), a male M5x0.8 threaded rod end (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance.
The 16 mm bore features a hard-anodized inner wall and an M5x0.8 air port. End-of-stroke deceleration relies on fixed NBR bumpers rather than an adjustable air cushion, meaning high-speed operations may require external shock absorbers. Grooves around the body accept AirTAC reed or electronic switches to track position, and the unit operates at speeds between 30 and 500 mm/s.

Routes small electronic panels using the male M5 rod end, applying precise 100.5 N force at 0.5 MPa while fitting into compact router housings.
Closes lightweight blister packaging molds where FKM seals withstand elevated ambient temperatures and the short 20 mm stroke delivers rapid cycles.
Drives a micro-valve for chemical dispensing, using the built-in magnet with an electronic switch to confirm exact fluid dosing positions.
When sizing this 16 mm bore actuator, compare its 100.5 N push at 0.5 MPa against adjacent options. Stepping down, the SDA12 provides 56.5 N; stepping up, the SDA20 offers 157.1 N. For this model, a safe working load is approximately 60 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity near 5.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 16 mm bore, 20 mm stroke, M5x0.8 port, male M5x0.8 rod thread, magnet included, and FKM seals.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke near its end without acting as a lock. If your application must maintain a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 16 mm bore double-acting cylinder provides 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 121 N pull at 0.7 MPa, with a theoretical maximum push of 21 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
It uses fixed NBR bumpers at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, add an external shock absorber. The -S option includes a piston magnet compatible with AirTAC reed or electronic switches mounted in the body grooves.
