The AirTAC AirTAC SDA50X80 Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 80mm 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 SDA50X80 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 into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body designs. This space efficiency is crucial when machinery footprint is tightly constrained.
This specific configuration features a 50 mm bore, an 80 mm stroke, and a PT1/4 port. The unit relies on a fixed NBR bumper at each end to decelerate the stroke end; because this is not an adjustable air cushion, high-energy cycles may require an external shock absorber. The piston rod measures 20 mm, terminating in a standard female M10x1.5 thread for straightforward load coupling.

Pushes medium-weight cartons off a sorting line using the 80 mm stroke, taking advantage of the 981.7 N push force to overcome side friction.
Raises a light pneumatic lift gate on a packaging machine where the short riveted body prevents interference with adjacent moving linkages.
Kicks stamped aluminum parts out of a small press, using the fixed NBR bumpers to absorb the sudden end-of-stroke impact.
When sizing this model, evaluate your force requirements carefully. Stepping down to the SDA40 provides 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 yields 1558.6 N at the same pressure. Based on the 981.7 N output, the safe working load is approximately 589 N (60% capacity), translating to a vertical lift capability of roughly 50 kg with a 2:1 safety margin.
Remember that a plain SDA body does not hold its position if air pressure drops or the valve is centered; the piston will drift. For applications requiring suspended load security, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 50 mm bore, 80 mm stroke, PT1/4 port, female rod thread, and note that this SKU lacks a piston magnet for sensing.
Quick checklist
This double-acting cylinder provides 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need the SDA50X80S variant for position sensing capabilities.
