The AirTAC AirTAC SDA20X110 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 SDA20X110 is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly minimizes overall length compared to round-body units, delivering 157.1 N of push force at 0.5 MPa. This specific 110 mm stroke configuration is a non-standard, made-to-order variant, exceeding the 100 mm maximum standard stroke for this 20 mm bore.
This model features an 8 mm piston rod and an M5x0.8 air port. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-speed approaches may require external shock absorption. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches. A plain compact actuator like this will drift if air pressure is lost, so a pilot-operated check valve is necessary for vertical load holding.

Pushes small cartons off a sorting line using a 110 mm travel distance, utilizing the 157.1 N extend force to overcome friction on the conveyor belt.
Extracts printed circuit boards from test fixtures, where the short riveted body keeps the workstation footprint to an absolute minimum.
Moves fluid vials between testing stations, relying on the 8 kg vertical lift capacity to raise and lower samples safely.
When sizing this 20 mm bore actuator, consider stepping down to the SDA16, which provides 100.5 N of push force at 0.5 MPa, or stepping up to the SDA25, which yields 245.4 N at the same pressure. For the SDA20X110, the safe working load is approximately 94 N (about 60% of the 157.1 N figure), translating to a vertical lift capacity of roughly 8 kg with a 2:1 safety margin. Confirm your ordering essentials: 20 mm bore, 110 mm non-standard stroke, M5x0.8 port, female rod thread, and no sensor magnet.
Quick checklist
This 20 mm bore cylinder generates 157.1 N push and 131.9 N pull at 0.5 MPa, or 219.9 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum push is 32 kgf at 1.0 MPa. The 110 mm stroke is non-standard and made-to-order, as it exceeds the 100 mm maximum standard stroke for this bore size.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option (e.g., SDA20X110S) to enable sensor functionality. Additionally, the fixed NBR bumper only decelerates the stroke end; it does not lock the piston, so an external rod lock is required to hold a position if air pressure drops.
