The AirTAC AirTAC SDA50X30S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 30mm 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 SDA50X30S 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 assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific configuration includes the S option, meaning it has a built-in piston magnet designed to interface with AirTAC magnetic reed or electronic switches housed in the grooves around the body. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, and the 20 mm rod terminates in a standard female M10x1.5 thread. Operating speeds span 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Uses the 981.7 N extend force to positively redirect heavy cartons on a high-speed logistics sorting line where a short 30 mm stroke minimizes the machine footprint.
Secures aluminum castings inside a machining center, taking advantage of the 20 mm rod and female M10x1.5 thread to hold the part firmly against cutting forces.
Acts as a pneumatic stop for inbound pallets on an assembly conveyor, utilizing the built-in S magnet to trigger an electronic switch and confirm the gate is raised.
When sizing this actuator, evaluate your force requirements against its 981.7 N push at 0.5 MPa, which translates to a safe working load of roughly 589 N or a 50 kg vertical lift with a 2:1 safety margin. If your application demands less force, stepping down to the SDA40 provides 628.3 N; conversely, if you need more thrust, the SDA63 offers 1558.6 N at the same 0.5 MPa. Keep in mind that a standard double-acting 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—implement an external rod lock or pilot-operated check valve if position holding is critical. To finalize your order, confirm the 50 mm bore, 30 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required S magnet option.
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 increases to 1374.4 N and the pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion, so you may need an external shock absorber for high-energy cycles. The S option provides a built-in magnet for position feedback, allowing you to mount either a reed or electronic switch directly into the body grooves.
