The AirTAC AirTAC SDA50X80SB 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 SDA50X80SB 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 keeps the axial footprint exceptionally short, fitting into machinery where longer profile or round-body units cannot. The 50 mm bore pairs with a PT1/4 port and a 20 mm piston rod to provide robust actuation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male-threaded M18x1.5 piston rod end (-B), offering a straightforward mechanical interface for your tooling. End-stop energy is managed solely by a fixed NBR bumper, which decelerates the piston near stroke completion rather than acting as a lock.

Pushes parcels from a high-speed sorting belt using the 981.7 N extend force, with the 80 mm stroke clearing the lane in milliseconds.
Drives the sealing head down onto corrugated boxes, utilizing the male M18x1.5 rod end to securely attach the clamping jaw.
Raises a light pallet gate using a safe vertical lift capacity of roughly 50 kg, fitting within tight conveyor frame depths.
When sizing this unit, consider stepping down to the SDA40, which provides 628.3 N of push at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. For the SDA50X80SB, a safe working load is approximately 589 N (about 60% of the 981.7 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 50 kg with a 2:1 safety margin. Ensure your ordering essentials cover the 50 mm bore, 80 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required sensor magnet.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the valve is centered—the piston will drift. If your application demands position holding 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 981.7 N and the pull force is 824.7 N. At 0.7 MPa, push is 1374.4 N and pull is 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, add an external shock absorber. It does not hold position on air loss; use an external rod lock or pilot-operated check valve if load holding is required.
