The AirTAC AirTAC SDA50X150 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 150mm 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 SDA50X150 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, piston, and rod to minimize axial mounting depth, providing a distinct footprint advantage in tight machinery layouts. The 50 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable service.
This specific configuration includes a 150 mm stroke, which exceeds the 130 mm maximum standard stroke for this bore size, making it a non-standard, made-to-order unit. The piston rod measures 20 mm with a default female M10x1.5 thread, and the air port is PT1/4. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. Because this SKU lacks the -S magnet option, it cannot support magnetic position sensing.

Drives a routing arm on a high-speed logistics conveyor to deflect parcels up to 50 kg onto secondary chutes using its 150 mm travel.
Provides 981.7 N of extend force at 0.5 MPa to push finished plastic components out of a molding die where axial depth is restricted.
Actuates a lowerator mechanism to position flat pallets for stacking, requiring an external check valve to prevent drifting under load.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N, allowing you to scale thrust precisely to the application. For the SDA50X150, the 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. Keep in mind that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. If your process demands strict position holding, specify an external rod lock or a pilot-operated check valve. To order, confirm the 50 mm bore, 150 mm non-standard stroke, PT1/4 port, female rod thread, and no magnet.
Quick checklist
This 50 mm bore double-acting cylinder provides a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, the push increases to 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, this specific SKU does not include a piston magnet. The -S variant is required to utilize the body sensor grooves with AirTAC reed or electronic switches. Additionally, this 150 mm unit is a made-to-order non-standard stroke, as the maximum standard stroke for a 50 mm bore is 130 mm.
