The AirTAC AirTAC SDA20X10SB Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 10mm 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 SDA20X10SB is a double-acting, single-rod compact cylinder engineered for tight axial spaces. A riveted unibody design drastically reduces mounting depth compared to conventional round-body units, yielding a 157.1 N push force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S) for position sensing and a male M6x1.0 threaded rod end (-B) for direct load coupling.
The 8 mm piston rod operates within a hard-anodized bore, while the 10 mm stroke is governed by a fixed NBR bumper at each end. These bumpers absorb end-stop impact but are not adjustable air cushions, meaning high-speed approaches may require external shock absorption. The integrated magnet supports AirTAC reed or electronic switches via the body grooves.

Ideal for short 10 mm ejector strokes on SMT machines, utilizing the male M6 rod end for precise vacuum nozzle actuation.
Provides consistent 157.1 N clamping force for thin film sealing jaws where minimal axial mounting depth is required.
Handles fast, short-travel fluid dispensing valve actuation, with the -S magnet triggering reed or electronic switches for exact dosing cycles.
When sizing this 20 mm bore unit, consider stepping down to the SDA16 (100.5 N push @0.5 MPa) for lighter duties, or up to the SDA25 (245.4 N push @0.5 MPa) if your load demands greater thrust. For the SDA20X10SB, the computed safe working load is approximately 94 N (about 60% of its 157.1 N capacity), translating to a vertical lift capability of roughly 8 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the rod. To confirm your ordering essentials: specify the 20 mm bore, 10 mm stroke, M5x0.8 port, built-in magnet (S), and the male M6x1.0 rod thread (B).
Quick checklist
This double-acting cylinder generates a push force of 157.1 N and a pull force of 131.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 219.9 N. The theoretical maximum push is 32 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, supports speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, the SDA20X10SB uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. Additionally, it does not feature a locking mechanism; the rod will drift if air pressure is lost. For high-speed cycles, add an external shock absorber, and use a pilot-operated check valve if you need to hold a load without live pressure.
