The AirTAC AirTAC SDA50X35B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 35mm 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 SDA50X35B 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 short riveted body design significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint in tight assemblies.
This specific configuration includes a male-thread piston rod end (M18x1.5) for secure mechanical coupling to your load. The unit operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Drives the folding mechanism on continuous carton packaging lines, utilizing the 981.7 N push force to snap heavy cardboard flaps into position securely.
Actuates a routing gate along a material handling conveyor, where the space-saving riveted body fits neatly within the 35 mm stroke constraint between parallel belts.
Pushes finished plastic parts out of small injection molds, taking advantage of the male M18x1.5 rod thread to attach custom ejector tooling securely.
When sizing this actuator, 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. The 50 mm bore offers a computed safe working load of roughly 589 N (about 60% of its 981.7 N capacity) and can vertically lift approximately 50 kg with a 2:1 safety margin.
Confirm your ordering essentials: 50 mm bore, 35 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no sensor magnet. Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the load; utilize an external rod lock or pilot-operated check valve if position holding is required.
Quick checklist
At 0.5 MPa this cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa the push increases to 1374.4 N. The theoretical maximum push is 200 kgf at the 1.0 MPa operating pressure limit.
The cylinder uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Additionally, it cannot hold a load if air pressure drops; the piston will drift, requiring an external rod lock or pilot-operated check valve for secure position holding.
