The AirTAC AirTAC SDA80X100SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 100mm 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 SDA80X100SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. By utilizing a riveted body assembly that integrates the barrel, rear cover, piston, and rod, it achieves a much shorter overall length than conventional round-body units, saving valuable machine mounting depth. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, operating efficiently across a 30-500 mm/s speed range.
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 thread (-B) on the 25 mm piston rod for secure load coupling. End-stop energy is managed solely by a fixed NBR bumper, which decelerates the piston near stroke completion rather than acting as a lock or adjustable air cushion. For high-inertia loads, adding an external shock absorber is advised to prevent impact damage.

Pushes heavy metal blanks out of a stamping die using 2513.3 N of extend force, where the short riveted body fits within tight press side-clearances.
Actuates a diverter gate on a high-throughput palletizing line, utilizing the 100 mm stroke and built-in magnet for solid-state switch positioning.
Shifts a heavy mold core with its male M22x1.5 rod end, relying on the 3518.6 N push at 0.7 MPa to overcome resin injection pressures.
Selecting this 80 mm bore model provides a 2513.3 N push at 0.5 MPa, offering a safe working load of roughly 1508 N (about 60% capacity) and 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, scaling up to the SDA100 provides 3927 N. Keep in mind that a plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the piston, so an external rod lock or pilot-operated check valve is necessary for position holding.
When requesting a quote, confirm the core ordering parameters: 80 mm bore, 100 mm stroke, PT3/8 port thread, the integrated magnet (-S), and the male M22x1.5 piston rod thread (-B).
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push force is 513 kgf at the 1.0 MPa operating pressure limit.
No. The -B option designates a male M22x1.5 piston rod thread, but the cylinder uses a fixed NBR bumper at each end to decelerate the stroke. It is not an adjustable air cushion, so external shock absorbers should be added for high-speed loads.
