The AirTAC SDA50X40N Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 40mm 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 SDA50X40N 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 axial mounting depth compared to round-body units, making it highly effective for machinery where space footprint is critical. The unit operates at speeds between 30 and 500 mm/s.
This specific configuration features a 50 mm bore, a 40 mm stroke, and a PT1/4 port. The hard-anodized inner bore minimizes wear, while fixed NBR bumpers absorb kinetic energy at the stroke ends. This SKU is supplied without a piston magnet, meaning it cannot directly host AirTAC reed or electronic switches.

Pushes medium-weight cartons off a main sorting line using its 981.7 N extend force, fitting neatly into tight transfer station frames.
Ejects formed plastic parts from low-clearance mold platens, where the short riveted body depth prevents interference with the press machinery.
Acts as a pneumatic stop for loaded pallets entering a wrap station, safely decelerating the load using its fixed NBR end bumpers.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, whereas moving up to the SDA63 provides 1558.6 N. To finalize your order, confirm the 50 mm bore, 40 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the absence of a sensor magnet. Note that this cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; utilize an external rod lock or pilot-operated check valve for secure positioning.
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 is 1374.4 N. The theoretical maximum push is 200 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
No, this specific SKU lacks the internal piston magnet. To use AirTAC reed or electronic switches, you must select the -S option. Additionally, end-stop deceleration is handled by fixed NBR bumpers, not an adjustable air cushion.
