The AirTAC AirTAC SDA50X110 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 110mm 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 SDA50X110 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. Its hard-anodized bore and two-way piston seal ensure reliable operation, while the 110 mm stroke extends to the upper limit of the 50 mm bore range which caps at 130 mm.
The short riveted body minimizes axial mounting depth, offering a distinct footprint advantage over longer round-body units. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot directly host position sensing without upgrading to the -S variant.

Actuates routing gates on high-speed logistics conveyors, utilizing the 110 mm stroke to push parcels smoothly between sorting lanes.
Drives mechanical arms to fold corrugated box flaps prior to tape sealing, where the compact riveted body keeps the packaging machinery footprint tight.
Raises lightweight product tiers within automated assembly cells, lifting loads up to 50 kg vertically with a 2:1 safety margin.
When sizing your application, stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, whereas stepping up to the SDA63 provides 1558.6 N. This SDA50X110 configuration provides a safe working load of roughly 589 N (about 60% of the 981.7 N figure), translating to a vertical lift capacity near 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 110 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a magnet. Note that this cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; adding an external rod lock or pilot-operated check valve is required for secure positioning.
Quick checklist
This 50 mm bore double-acting 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 push is 200 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and cycles at speeds of 30-500 mm/s.
This specific SKU does not include a piston magnet, so it cannot support reed or electronic switches unless you specify the -S option. Additionally, end-of-stroke deceleration relies solely on a fixed NBR bumper; it is not an adjustable air cushion, so external shock absorbers are advised for high-energy loads.
