The AirTAC AirTAC SDA80X35SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 35mm 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 SDA80X35SB is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it saves valuable mounting depth where conventional round-body units cannot fit. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, with a theoretical maximum output of 513 kgf at 1.0 MPa.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and a male M22x1.5 threaded piston rod (-B) for secure load coupling. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Operating speed ranges from 30-500 mm/s, fed through a PT3/8 port.

Knocks heavy stamped metal panels out of a press die using 2513.3 N of extend force, with the short riveted body fitting into tight press side-cavities.
Separates large plastic injection molded housings from static mold halves, utilizing the male M22x1.5 rod end for rigid coupling to the stripper plate.
Acts as a heavy vertical stop in palletizing lines, lifting loads up to 128.1 kg with a 2:1 safety margin while accepting AirTAC reed or electronic switches for position feedback.
Selecting this 80 mm bore model provides a robust 2513.3 N push at 0.5 MPa, yielding a safe working load of roughly 1508 N (about 60% capacity) or a vertical lift capability of approximately 128.1 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa; conversely, upgrading to the SDA100 provides 3927 N at 0.5 MPa for heavier demands. When ordering, confirm the 80 mm bore, 35 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the integrated sensor magnet. Keep in mind that a standard compact cylinder drifts if air pressure is lost or the valve is centered—the fixed bumper only decelerates the stroke end and does not function as a locking brake, so an external rod lock or pilot-operated check valve is required to hold a load safely.
Quick checklist
This 80 mm bore double-acting cylinder outputs 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
Deceleration at stroke ends relies on a fixed NBR bumper, which is not a field-adjustable air cushion; for high-energy cycles, add an external shock absorber. Because this model includes the -S magnet, you can mount AirTAC reed or electronic switches directly into the body grooves for position detection.
