The AirTAC AirTAC SDA50X30B 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 SDA50X30B is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies. This specific SKU features a male M18x1.5 piston rod thread for robust mechanical coupling to your load.
The bore is hard-anodized for longevity, operating at speeds between 30 and 500 mm/s. End-stop deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Note that this configuration omits the piston magnet, so position sensing is not supported without the -S option.

Actuates routing gates on logistics conveyor lines, utilizing the 981.7 N push force to swiftly pivot heavy cardboard cartons onto secondary sorting tracks.
Drives the mechanical arms that fold inner flaps on automated palletizing machines, where the short riveted body minimizes interference with adjacent wrapping equipment.
Ejects formed aluminum castings from small die-casting presses, using the male M18x1.5 rod thread to securely attach a custom threaded knockout tool.
Selecting this 50 mm bore provides a theoretical safe working load of roughly 589 N (about 60% of the 981.7 N figure 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, the SDA40 generates 628.3 N at 0.5 MPa; for heavier demands, the SDA63 outputs 1558.6 N. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock or pilot-operated check valve is necessary for strict position holding.
When ordering, confirm the 50 mm bore, 30 mm stroke, PT1/4 port, and the male M18x1.5 rod thread (-B). The maximum standard stroke for this bore is 130 mm; exceeding this requires a guided cylinder to prevent rod deflection.
Quick checklist
This double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, and 1374.4 N push at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA50X30BS variant to utilize the built-in sensor grooves. Additionally, it uses a fixed NBR bumper for end stops, not an adjustable air cushion.
