The AirTAC SDA80X50SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X50SB is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight layouts. Driven by a 25 mm piston rod, this specific configuration includes a built-in magnet for position sensing and a male M22x1.5 thread for robust load coupling.
End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers are recommended for high-energy cycles. The integrated piston magnet supports AirTAC reed or electronic switches fitted into the body grooves.

Provides the 2513.3 N push force required to knock heavy stamped metal panels out of progressive dies within a confined press bed.
Raises 128 kg layer-forming platforms using the male M22x1.5 rod end, fitting neatly into tight vertical lift columns where profile cylinders are too long.
Secures mold halves during low-pressure closing sequences, using the built-in magnet to confirm closed position via solid-state switches.
When sizing this unit, verify if the adjacent bores better suit your requirements: stepping down to the SDA63 yields 1558.6 N push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N. To confirm your ordering essentials for this model: 80 mm bore, 50 mm stroke, PT3/8 port, male M22x1.5 rod thread (B), and a piston magnet (S).
Remember that a standard compact actuator will not hold a load if air pressure drops or the valve is centered, as the piston drifts freely and the fixed bumper only decelerates near the stroke end. To suspend a load safely without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, push is 3518.6 N and pull is 3175 N. The theoretical maximum push is 513 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper to decelerate the piston at the stroke ends, which is not an adjustable air cushion or a locking brake. For high-speed cycles, add external shock absorbers. The included -S magnet allows tracking by AirTAC reed or electronic switches mounted in the body grooves.
