The AirTAC AirTAC SDA50X130 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm 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 SDA50X130 is a double-acting single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. Its riveted assembly significantly reduces overall axial length compared to conventional round-body units, saving valuable mounting depth in tight machinery footprints. The hard-anodized bore and two-way piston seal ensure durable, low-friction operation across a 30-500 mm/s speed range.
This specific configuration features a 130 mm stroke, which is a non-standard made-to-order length exceeding the 120 mm standard maximum for this 50 mm bore. End-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. The Ø20 mm piston rod utilizes a female M10x1.5 thread, and because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Drives a routing flap on a high-speed logistics conveyor, using the 130 mm travel to redirect parcels up to 50 kg into sorting chutes.
Executes synchronized side-flap folding on a continuous carton sealing line, where the short body length preserves adjacent roller spacing.
Raises lower-tier product trays within a compact packaging cell, lifting approximately 50 kg payloads vertically with a 2:1 safety margin.
When sizing this actuator, evaluate your force margins carefully. If you need less thrust, stepping down to the SDA40 provides 628.3 N of push at 0.5 MPa; conversely, scaling up to the SDA63 yields 1558.6 N at the same pressure. For this 50 mm bore, a safe working load is approximately 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin.
Ensure your ordering essentials are correct: 50 mm bore, 130 mm non-standard stroke, PT1/4 port, female M10x1.5 rod thread, and no sensor magnet. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and does not act as a locking brake. To suspend a load safely without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum thrust is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S variant to utilize the built-in sensor grooves around the body.
