The AirTAC SDA20X130 Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 130mm 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 SDA20X130 is a double-acting single-rod compact cylinder engineered for a 20mm bore and an extended 130mm stroke. It generates 157.1 N of push force and 131.9 N of pull force at 0.5 MPa, making it suitable for moderate actuation tasks. Because this 130mm stroke exceeds the 100mm maximum standard length for this bore size, it is produced as a non-standard made-to-order unit.
The short riveted body assembly significantly reduces axial mounting depth compared to round-body alternatives, freeing up valuable machine footprint. The bore features a hard-anodized inner wall and uses a fixed NBR bumper at each end to decelerate the piston near stroke limits. This specific SKU lacks a piston magnet, meaning it cannot support magnetic sensing without upgrading to the -S variant.

Pushes lightweight cardboard cartons on a distribution line using 157.1 N of extend force, where the compact body minimizes frame protrusion.
Extends 130mm to push printed circuit boards out of an inspection fixture, operating safely within the 94 N working load limit.
Moves fluid sample trays between testing stations, taking advantage of the 30-500 mm/s speed range without requiring position sensing.
When sizing this actuator, consider stepping down to the SDA16, which provides 100.5 N of push at 0.5 MPa, or moving up to the SDA25, which yields 245.4 N at the same pressure. To order, confirm the 20mm bore, 130mm non-standard stroke, M5x0.8 port, female M4x0.7 rod thread, and no magnet. If your application must hold a load without live pressure, note that a plain cylinder will drift on air loss; the fixed bumper only decelerates the end of travel and acts as neither a lock nor a brake, so an external rod lock or pilot-operated check valve is required.
Quick checklist
This 20mm bore double-acting cylinder provides 157.1 N push and 131.9 N pull at 0.5 MPa, and 219.9 N push at 0.7 MPa. The theoretical maximum push is 32 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and the speed range is 30-500 mm/s.
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 to add a magnet for sensing. Additionally, it uses fixed NBR bumpers rather than adjustable air cushions, so external shock absorbers are recommended for high-speed operations.
