The AirTAC AirTAC SDA20X60H 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 SDA20X60H is a double-acting, single-rod compact cylinder engineered with a 20 mm bore and 60 mm stroke. It generates 157.1 N of push force and 131.9 N of pull force at 0.5 MPa. This specific SKU utilizes a fluororubber (FKM) seal, providing enhanced resistance to higher temperatures and oily environments compared to standard NBR. The hard-anodized bore interior ensures long service life, while the integrated body grooves allow for straightforward sensor integration when a magnet is specified.
A short, riveted assembly joins the barrel, rear cover, piston, and 8 mm rod, significantly reducing axial mounting depth where a conventional round-body actuator will not fit. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks a piston magnet, it cannot support magnetic switching; adding the -S option enables reed or electronic switch sensing.

Ideal for opening and closing small access doors on CNC machining centers where axial depth is restricted and the FKM seal withstands splash coolant.
Provides the precise 157.1 N push force required to clamp thin polymer films in heat-sealing fixtures without crushing the product.
Drives lightweight routing flaps on package conveyor lines, offering a safe 8 kg vertical lift capacity with a 2:1 safety margin.
When sizing this actuator, verify your force requirements in both directions. Stepping down to the SDA16 yields 100.5 N of push at 0.5 MPa, while stepping up to the SDA25 provides 245.4 N at the same pressure. Based on the 157.1 N output at 0.5 MPa, the safe working load is approximately 94 N (about 60% capacity), which translates to a vertical lift capability of roughly 8 kg with a 2:1 safety margin. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the piston near the stroke end and does not function as a locking brake. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve is required.
For ordering, confirm the 20 mm bore, 60 mm stroke, M5x0.8 port, and the absence of a piston magnet. The standard female M4x0.7 rod-end thread couples directly to your load, though side loading should be strictly avoided on this compact 8 mm rod. The FKM seal option makes this model particularly suitable for harsher thermal conditions.
Quick checklist
This 20 mm bore 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 force is 32 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switching. You would need to specify the -S option to add a magnet. Additionally, end-of-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
