The AirTAC AirTAC SDA50X110S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 110mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X110S is a double-acting single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to conventional round-body units, providing a highly space-efficient footprint for tight machine layouts.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches via the body grooves. It features a 20 mm piston rod, a PT1/4 air port, and relies on a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion.

Drives the folding mechanism on automated packaging lines, utilizing the 110 mm stroke to open and close corrugated carton flaps with reliable 981.7 N force.
Actuates routing gates on a conveyor system to redirect heavy pallets, where the short riveted body saves critical axial space within the conveyor frame.
Raises machining jigs to a precise working height, safely handling loads up to 50 kg vertically while benefiting from the integrated magnet for end-of-stroke confirmation.
When sizing this unit, consider stepping down to the SDA40 which provides 628.3 N of push force at 0.5 MPa, or moving up to the SDA63 which yields 1558.6 N at the same pressure. For the SDA50X110S, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), allowing for a vertical lift of roughly 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 110 mm stroke, PT1/4 port, female rod-end thread (M10x1.5), and the required -S magnet.
Note that a plain compact cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the motion near the stroke end and acts as neither a lock nor a brake. If your application requires position holding without live pressure, an external rod lock or pilot-operated check valve must be installed.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push is 1374.4 N and the pull is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, add an external shock absorber. The built-in magnet (-S) works with AirTAC reed or electronic switches in the body grooves for position detection.
