The AirTAC AirTAC SDA50X60S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 60mm 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 SDA50X60S 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. Driven by a 50 mm bore and a 60 mm stroke, it utilizes a hard-anodized inner wall and a two-way piston seal to maintain reliable performance across a 30-500 mm/s speed range. Because the -S option is present, a built-in piston magnet enables position detection using an AirTAC reed or electronic switch seated in the body grooves.
The short riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint. End-of-travel impact is managed strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent damage. This model uses a PT1/4 port and a 20 mm rod to efficiently transfer power to the load.

Pushes medium-weight cartons off a main sorting line using 981.7 N of thrust, where the 60 mm stroke provides just enough travel to clear the adjacent belt.
Raises a lightweight palletizing gate in a compact frame, taking advantage of the short riveted body to fit within tight vertical mounting constraints.
Ejects formed plastic bottles from a blow molding station, utilizing the built-in magnet to trigger a solid-state switch and confirm part release.
When sizing this actuator, stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N, allowing you to scale thrust precisely to your application. For this specific configuration, the safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 60 mm stroke, PT1/4 port, female M10x1.5 rod-end thread, and the required -S magnet.
Keep in mind that a standard double-acting cylinder does not hold its position 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 demands strict load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, the SDA series relies on a fixed NBR bumper at each end to decelerate the piston. It is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
