The AirTAC AirTAC SDA50X45NH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 45mm 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 SDA50X45NH is a double-acting, single-rod compact cylinder engineered with a 50 mm bore and 45 mm stroke. Its riveted assembly shrinks the total axial footprint, fitting easily into tight machine layouts where longer profile alternatives fail. This specific SKU features an FKM (fluororubber) seal variant, making it well-suited for environments involving higher temperatures or oil exposure.
At 0.5 MPa operating pressure, it generates 981.7 N of push force and 824.7 N of pull force. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not a field-adjustable air cushion. Because this configuration omits the -S magnet code, it cannot directly host AirTAC reed or electronic switches.

Drives the folding mechanisms on packaging lines, utilizing the 45 mm stroke to tuck flaps rapidly while the short riveted body conserves floor space.
Actuates routing gates on conveyor systems, delivering 981.7 N of push force at 0.5 MPa to reliably redirect heavy product pallets.
Pushes finished plastic parts out of injection molds, where the FKM seals provide necessary resilience against elevated ambient heat.
When sizing this actuator, compare its 981.7 N push at 0.5 MPa against adjacent bores: the SDA40 provides 628.3 N, while the SDA63 offers 1558.6 N. Based on the 0.5 MPa figure, a safe working load is roughly 589 N (about 60 percent capacity), translating to a vertical lift capability of approximately 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 45 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the FKM seal option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift, and the fixed bumper only slows travel near the end of the stroke rather than locking it. If your application requires static holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa, or 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a speed range of 30-500 mm/s.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the -S option to utilize the body sensor grooves. Additionally, end-stroke deceleration is handled by a fixed NBR bumper, not an adjustable air cushion.
