The AirTAC AirTAC SDA50X15SG Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 15mm 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 SDA50X15SG is a double-acting single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Driven by a 50 mm bore and a 15 mm stroke, its short riveted body drastically reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. The hard-anodized bore and two-way piston seal ensure durable, leak-free operation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a -G BSPP port thread option on the standard PT1/4 ports. End-stops rely on a fixed NBR bumper that decelerates the piston near stroke end rather than an adjustable air cushion. For high kinetic energy loads, slowing the approach or adding external shock absorbers is advised.

Deploys the 15 mm stroke to rapidly fold corrugated cardboard flaps on packaging lines, utilizing the 981.7 N push force to overcome board stiffness reliably.
Actuates a sorting diverter arm on a parcel conveyor, where the compact riveted body minimizes protrusion into tight transfer zones while moving 50 kg loads.
Secures aluminum castings inside a machining center; the built-in magnet enables reed or electronic switches to confirm clamp engagement before the spindle starts.
When sizing this unit, compare its 981.7 N push at 0.5 MPa against adjacent bores: the SDA40 provides 628.3 N if your load is lighter, while the SDA63 offers 1558.6 N for heavier demands. Based on the 981.7 N figure, a safe working load is approximately 589 N (about 60% capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 15 mm stroke, PT1/4-G porting, female M10x1.5 rod thread, and the required magnetic switch.
Note that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake. If your application requires strict load holding on air loss, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not hold its load if air is lost; the piston drifts, so an external rod lock or pilot-operated check valve is required for position holding.
