The AirTAC AirTAC SDA50X30SBH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 30mm 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 SDA50X30SBH is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 30 mm stroke. It delivers a robust 981.7 N push force at 0.5 MPa, making it suitable for medium-duty industrial handling. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male M18x1.5 threaded rod end (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance.
The riveted body design significantly reduces axial mounting depth compared to traditional round-body cylinders, saving valuable machine footprint. Instead of an adjustable air cushion, the unit relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits. For high kinetic energy loads, operators should add an external shock absorber or slow the approach speed, as the bumper is not a locking mechanism.

Routes heavy beverage containers on a packaging conveyor using the 981.7 N extend force, while the FKM seals withstand occasional washdown lubricants.
Actuates a light palletizing lift gate where the short riveted body saves vertical mounting space and the male M18x1.5 rod secures the heavy linkage.
Clamps cast aluminum engine blocks in a machining center, utilizing the 824.7 N retract force and the -S magnet to confirm clamp status via a reed or electronic switch.
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 safe working load of approximately 589 N (about 60% of its 981.7 N capacity) and can vertically lift around 50 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 50 mm bore, 30 mm stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and a magnetic piston.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the directional valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. If your application requires strict load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 is 200 kgf at the maximum operating pressure of 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. If operating at high speeds, add an external shock absorber. Additionally, it does not hold a load if air is lost; the piston drifts, requiring an external rod lock or pilot-operated check valve for secure positioning.
