The AirTAC AirTAC SDA50X110SB 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 SDA50X110SB is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth compared to traditional round-body units, making it highly effective for machinery where space footprint is critical. This specific configuration includes a built-in piston magnet for position sensing and a male M18x1.5 threaded rod end.
This model relies on a fixed NBR bumper at each end to decelerate the piston near stroke completion rather than an adjustable air cushion. Because it operates at a 110 mm stroke, buyers should ensure adequate external guidance to prevent side loading on the 20 mm piston rod. The integrated magnet allows direct mounting of AirTAC reed or electronic switches along the body grooves for precise end-position feedback.

Raises a lightweight 50 kg pallet gate fixture with a 2:1 safety margin, utilizing the 110 mm stroke to clear vertical obstructions.
Adjusts the position of a shrink-wrap film roll assembly, using the male M18x1.5 rod end to secure the tensioning bracket.
Selecting this 50 mm bore provides a safe working load of roughly 589 N (about 60% of the 981.7 N push at 0.5 MPa), translating to a vertical lift capacity of approximately 50 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA40 yields 628.3 N at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N for heavier demands. Keep in mind that a plain compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For load holding, an external rod lock or pilot-operated check valve is required. When ordering, confirm the 50 mm bore, 110 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the included magnetic sensor 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 force is 1374.4 N. The theoretical maximum push force 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.
No, it uses a fixed NBR bumper at each end to decelerate the piston near stroke completion, which is not an adjustable air cushion. Additionally, it does not function as a lock or brake; if air is lost or the valve is centered, the piston will drift. An external rod lock or pilot-operated check valve is required for load holding.
