The AirTAC AirTAC SDA50X80S 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 SDA50X80S is a double-acting single-rod compact cylinder engineered to deliver a substantial 981.7 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an ultra-short profile, drastically reducing axial mounting depth compared to conventional round-body units. This space efficiency is critical when designing tighter machine footprints.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The unit relies on a fixed NBR bumper at each stroke end to absorb impact rather than an adjustable air cushion. Operating at speeds from 30-500 mm/s, it features a 20 mm piston rod and a PT1/4 port to handle the required air volume.

Pushes heavy product pallets sideways off a main conveyor line using the 981.7 N extend force, fitting within the tight 80 mm stroke envelope.
Drives mechanical arms to fold corrugated carton flaps prior to sealing, benefiting from the 30-500 mm/s speed range and space-saving riveted body.
Raises and lowers light material handling gates, where the 50 kg vertical lift capacity with a 2:1 margin provides reliable gravity-assisted positioning.
Selecting this 50 mm bore yields a 981.7 N extend force at 0.5 MPa, which translates to a safe working load of roughly 589 N or a 50 kg vertical lift with a 2:1 safety margin. If your application requires less force, the adjacent SDA40 provides 628.3 N; if you need more power, stepping up to the SDA63 offers 1558.6 N. Remember that a plain compact cylinder drifts when air pressure is lost or a valve centers, so incorporate an external rod lock or pilot-operated check valve if the load must be held securely.
When ordering, confirm the 50 mm bore, 80 mm stroke, PT1/4 port, and the -S magnet option. The piston rod end utilizes a female M10x1.5 thread, though a male M18x1.5 thread is available if specified. Because the fixed NBR bumper cannot be adjusted, high-energy cycles may require an external shock absorber to prevent wear.
Quick checklist
At 0.5 MPa, the push force is 981.7 N and the pull force is 824.7 N. At 0.7 MPa, the push force is 1374.4 N and the pull force is 1154.5 N. The theoretical maximum push force is 200 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumpers only decelerate the piston near the stroke ends and do not act as a lock or brake. An external rod lock or pilot-operated check valve is required for position holding.
