The AirTAC AirTAC SDA50X45B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 45mm 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 SDA50X45B is a double-acting, single-rod compact cylinder engineered to deliver a robust 981.7 N of push force at 0.5 MPa. Built with a hard-anodized bore and a two-way piston seal, its riveted body design drastically reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies.
This specific configuration includes a male M18x1.5 threaded piston rod for secure mechanical coupling to your load. It relies on a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives the folding mechanism on continuous packaging lines, utilizing the 45 mm stroke and male M18x1.5 rod to push heavy cardboard flaps into position for sealing.
Provides steady 981.7 N clamping force at 0.5 MPa to hold sheet metal guides in place during bending operations where axial space is strictly limited.
Actuates a diverter gate on a palletizing machine, moving 50 kg loads vertically with a 2:1 safety margin while fitting within the conveyor's shallow frame.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 reduces the push output to 628.3 N at 0.5 MPa, while moving up to the SDA63 increases it significantly to 1558.6 N. Based on the 981.7 N output at 0.5 MPa, a safe working load is approximately 589 N (60% capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety margin.
Keep in mind that a standard compact 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 rod. For suspended or vertical loads that must hold position without live pressure, an external rod lock or pilot-operated check valve is required. To order, confirm the 50 mm bore, 45 mm stroke, PT1/4 port, and the male M18x1.5 rod thread.
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, the push increases to 1374.4 N. The theoretical maximum push force is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke, not a field-adjustable air cushion. Additionally, because it lacks the -S magnet code, it cannot support AirTAC reed or electronic switches; you would need the -S variant for position sensing.
