The AirTAC AirTAC SDA50X80B 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 SDA50X80B 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 riveted body design significantly reduces axial mounting depth compared to conventional round-body units, making it ideal for machinery where space is strictly limited. The unit operates at speeds between 30-500 mm/s.
This specific configuration features a male M18x1.5 threaded piston rod end for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this SKU lacks the -S magnet option, it cannot support magnetic reed or electronic switches.

Drives the folding mechanism on packaging lines, using the 80 mm stroke to fold heavy cardboard flaps with 981.7 N of extend force.
Actuates a routing gate on a conveyor system, where the short riveted body minimizes footprint and the male M18x1.5 rod securely mounts the diverter arm.
Pushes finished plastic parts out of an injection molding fixture, relying on the fixed NBR bumper to absorb the impact at the end of the 80 mm extension.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA40 yields 628.3 N of push force at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. The 50 mm bore offers a safe working load of roughly 589 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 50 kg with a 2:1 safety margin.
For ordering, confirm the 50 mm bore, 80 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a standard actuator will not hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. Use an external rod lock or pilot-operated check valve if position holding is required.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981.7 N of push force and 824.7 N of pull force. 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 support reed or electronic switches. You would need the -S option variant for sensing capabilities. Additionally, it uses a fixed NBR bumper for end stops, not an adjustable air cushion.
