The AirTAC AirTAC SDA20X110SB Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 110mm 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 SDA20X110SB is a double-acting, single-rod compact cylinder engineered with a hard-anodized bore and a two-way piston seal. It delivers a push force of 157.1 N and a pull force of 131.9 N at 0.5 MPa. Equipped with a built-in magnet (-S) and a male M6x1.0 piston rod thread (-B), this unit is configured for precise actuation tasks requiring position feedback and specific load coupling.
This model features a 110 mm stroke, which exceeds the 100 mm maximum standard stroke for a 20 mm bore, making it a non-standard, made-to-order configuration. The short riveted body saves valuable axial mounting depth where a round-body unit will not fit. End-stops rely on a fixed NBR bumper that decelerates the piston near stroke end; it is not an adjustable air cushion, so adding an external shock absorber is advised for high-energy cycles.

Pushes lightweight cardboard cartons between sorting lanes on a packaging conveyor, utilizing the 110 mm stroke and 157.1 N extend force to clear the belt path efficiently.
Advances a locating pin to secure circuit boards during pick-and-place assembly, relying on the male M6 rod thread for precise tooling attachment and the internal magnet for position confirmation.
Ejects filled test tube racks from a diagnostic carousel, where the compact riveted body minimizes footprint inside a crowded instrument enclosure and the fixed NBR bumper softens the ejection stop.
When sizing this actuator, stepping down to the SDA16 bore yields 100.5 N of push force at 0.5 MPa, while stepping up to the SDA25 bore provides 245.4 N. The 20 mm bore here offers a calculated safe working load of roughly 94 N (about 60% of its 157.1 N capacity) and can vertically lift approximately 8 kg with a 2:1 safety margin. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
Confirm your ordering essentials: this SKU specifies a 20 mm bore, 110 mm non-standard stroke, M5x0.8 air port, an internal magnet for reed or electronic switches, and a male-threaded M6x1.0 rod end. Note that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered—the piston will drift. To maintain vertical position without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20 mm bore 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 force is 219.9 N and the pull force is 184.7 N. The theoretical maximum push force is 32 kgf at the maximum operating pressure of 1.0 MPa.
No, the piston will drift if air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not function as a locking brake. To suspend a load safely, you must add an external rod lock or a pilot-operated check valve to the pneumatic circuit.
