The AirTAC AirTAC SDA50X100B Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm 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 SDA50X100B is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too long. The internal bore receives a hard-anodized treatment paired with a two-way piston seal for extended lifespan.
This specific configuration includes the B option, providing a male M18x1.5 threaded piston rod end for secure mechanical coupling to your load. Because this unit lacks the S magnet code, it cannot host AirTAC reed or electronic switches. Deceleration at the stroke extremes relies strictly on fixed NBR bumpers rather than a field-adjustable air cushion.

Drives a routing flap on a logistics sorting line, utilizing the 100 mm stroke to redirect parcels efficiently into secondary chutes.
Deploys a mechanical arm to tuck minor flaps on a corrugated box sealing machine prior to tape application.
Raises a lightweight product tier during robotic palletizing, taking advantage of the compact body depth to fit within tight Z-axis clearances.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 reduces the 0.5 MPa push capacity to 628.3 N, while moving up to the SDA63 increases it to 1558.6 N. For the SDA50X100B, the 981.7 N output translates to a safe working load of roughly 589 N, or a vertical lift of about 50 kg with a 2:1 safety margin. Ensure your ordering essentials are correct: 50 mm bore, 100 mm stroke, PT1/4 port, male M18x1.5 rod thread, and no sensor magnet.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the directional valve centers; the piston will drift. If your application demands position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 981.7 N of push force and 824.7 N of pull force. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No adjustable air cushion is available; end-stop deceleration relies solely on fixed NBR bumpers, so you should slow the approach or add external shock absorbers for high-energy loads. Additionally, this specific SKU lacks the piston magnet, meaning it cannot support reed or electronic switches.
