The AirTAC AirTAC SDA20X60S Compact Cylinder | 20mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø20mm bore and 60mm 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 SDA20X60S is a double-acting single-rod compact cylinder engineered for tight machinery layouts. It generates 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. The riveted body assembly significantly reduces axial mounting depth compared to round-body alternatives, making it highly effective for footprint optimization. A built-in piston magnet enables position detection via AirTAC reed or electronic switches fitted into the body grooves.
This 20 mm bore unit features an 8 mm piston rod and an M5x0.8 air port. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Operating speed ranges from 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Actuates routing gates on packaging lines where the 60 mm stroke and 157.1 N push force easily redirect small to medium parcels.
Pushes printed circuit boards out of testing fixtures, utilizing the short riveted body to fit within dense semiconductor machinery.
Moves diagnostic trays in automated analyzers, relying on the built-in magnet to trigger reed or electronic switches for precise positioning.
Selecting this model provides a safe working load of roughly 94 N (about 60% of the 157.1 N push at 0.5 MPa), which translates to a vertical lift capacity of approximately 8 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA16 yields 100.5 N at 0.5 MPa; conversely, upgrading to the SDA25 provides 245.4 N. Remember that a plain 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 load. For secure positioning, integrate an external rod lock or pilot-operated check valve. Ensure your ordering essentials specify the 20 mm bore, 60 mm stroke, M5x0.8 port, the -S magnet, and the default female M4x0.7 rod thread.
Quick checklist
This double-acting cylinder delivers 157.1 N push and 131.9 N pull at 0.5 MPa, 219.9 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum push of 32 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa.
No, the SDA20X60S uses a fixed NBR bumper at each end to decelerate the piston, not an adjustable air cushion. For high-speed or high-energy loads, you should slow the approach speed or add an external shock absorber.
