The AirTAC AirTAC SDA63X80SB Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm 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 SDA63X80SB is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted body design integrates the barrel, rear cover, piston, and rod into a highly unified structure, drastically reducing axial mounting depth where a conventional round-body unit would be too bulky. The hard-anodized bore minimizes friction, while the integrated piston magnet enables precise position detection.
This specific configuration includes an 80 mm stroke and a male M18x1.5 threaded piston rod end for secure mechanical load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should control approach speeds or add external shock absorbers for high-energy loads. The body features standard grooves for mounting AirTAC reed or electronic switches.

Secures machining pallets inside automated cells, utilizing the 1558.6 N extend force to lock heavy fixtures firmly in place during high-speed milling operations.
Raises bulk cardboard cartons from lower conveyor tiers to upper filling lines, where the 79.4 kg vertical lift capacity handles heavy packaging materials reliably.
Drives secondary ejection arms in plastic molding plants, using the male M18x1.5 rod end to push finished components clear of the mold base safely.
When sizing this unit, consider stepping down to the SDA50, which yields 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for a substantial 2513.3 N output. For this 63 mm bore, a safe working load is approximately 935 N (about 60% of the 1558.6 N capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 80 mm stroke, PT1/4 port, male M18x1.5 rod thread, and the required magnetic switch.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds 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 or a locking brake; for high kinetic energy loads, you should add an external shock absorber. Because this model includes the S option, it has a built-in magnet compatible with AirTAC reed or electronic switches mounted in the body grooves.
