The AirTAC AirTAC SDA50X30BH 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 SDA50X30BH is a double-acting single-rod compact cylinder engineered to deliver a robust 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an exceptionally short axial package, drastically reducing mounting depth where a conventional round-body unit would not fit. This specific configuration includes a male M18x1.5 piston rod end for secure mechanical load coupling and an FKM (fluororubber) seal variant for enhanced thermal and oil resistance.
The 50 mm bore features a hard-anodized inner wall and a two-way piston seal, operating at speeds from 30 to 500 mm/s via PT1/4 ports. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; position sensing requires external methods.

Positions and squares printed circuit boards on a conveyor line prior to wave soldering, utilizing the 981.7 N push force to overcome guide friction.
Drives mechanical arms to tuck corrugated carton flaps before tape sealing, where the short 30 mm stroke and male M18x1.5 rod provide precise, compact actuation.
Raises spring-loaded stopper pins to catch incoming pallets on a packaging conveyor, safely absorbing impact via the fixed NBR end bumpers.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA40 provides 628.3 N of push at 0.5 MPa, whereas stepping up to the SDA63 yields 1558.6 N. For the SDA50X30BH, the safe working load is approximately 589 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 30 mm stroke, PT1/4 port, male M18x1.5 rod thread, and FKM seals.
Remember that a standard compact cylinder does not hold its position if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the load near the stroke end rather than locking it. If your application demands fail-safe load holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder generates 981.7 N of push force and 824.7 N of pull force. 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 the operating speed spans 30 to 500 mm/s.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches in the body grooves. Additionally, the fixed NBR bumpers are not adjustable air cushions; for high-energy cycles, you should add external shock absorbers or slow the approach speed.
