The AirTAC SDA50X150S Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 150mm 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 SDA50X150S 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, saving valuable machine footprint in tight assemblies. This specific configuration includes a 150 mm stroke, which exceeds the 130 mm standard maximum for this 50 mm bore, making it a non-standard, made-to-order item.
The unit features a hard-anodized bore and a fixed NBR bumper at each end to decelerate the piston near stroke limits; it is not an adjustable air cushion. Equipped with a built-in piston magnet (-S), it supports AirTAC reed or electronic switches via the body grooves for precise position sensing. The 20 mm rod uses an M10x1.5 female thread, and buyers should note that a plain cylinder drifts when air is lost, requiring an external rod lock for strict load holding.

Drives diverter arms on packaging lines to route cartons, utilizing the 981.7 N extend force to push boxes smoothly at cycling speeds up to 500 mm/s.
Ejects formed metal or plastic parts from small presses, relying on the 824.7 N retract force to pull the tooling back before the next machine cycle.
When sizing this model, compare its 981.7 N push at 0.5 MPa against adjacent bores: stepping down to the SDA40 yields 628.3 N, while stepping up to the SDA63 provides 1558.6 N. Because this 150 mm stroke is non-standard, allow extra lead time for made-to-order fulfillment.
To confirm your ordering essentials: specify the 50 mm bore, 150 mm stroke, PT1/4 port, the -S magnet for sensing, and the female M10x1.5 rod thread. Remember that the fixed rubber bumper only absorbs end-stop energy; for high-speed approaches, add external shock absorption. If the application must hold a load without live pressure, install a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and speeds of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits; it is not an adjustable air cushion. The bumper is not a lock or brake, so the piston will drift if air pressure is lost or the valve is centered. For load holding, you must add an external rod lock or pilot-operated check valve.
