The AirTAC SDA20X130S 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 SDA20X130S is a double-acting single-rod compact cylinder engineered to deliver 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to round-body units, making it highly effective for tight machinery footprints. The 8 mm piston rod features an M4x0.7 female thread, and the hard-anodized bore ensures long service life.
Because the 130 mm stroke exceeds the 100 mm maximum standard for this 20 mm bore, this unit is a non-standard, made-to-order configuration. It includes the S option, meaning a built-in piston magnet enables position sensing via an AirTAC reed or electronic switch mounted in the body grooves. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.

Pushes lightweight cardboard cartons on a distribution belt at speeds up to 500 mm/s, utilizing the 157.1 N extend force to deflect parcels into secondary chutes.
Drives a low-friction pick-and-place head for electronic assembly, relying on the built-in magnet to trigger an electronic switch for precise 130 mm positioning.
Maintains controlled tension on a packaging web line, where the compact riveted body saves axial space and the fixed NBR bumpers absorb rapid stroke ends.
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. For this specific made-to-order 130 mm stroke, confirm your requirements for the M5x0.8 port, the female rod thread, and the S magnet code.
Keep in mind that a standard SDA body does not hold its load if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near the end without acting as a lock. If your application requires vertical load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 20 mm 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. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds from 30-500 mm/s.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Because 130 mm exceeds the 100 mm standard stroke limit for this bore, it is a made-to-order item; for high-energy cycles, add an external shock absorber or slow the approach speed.
