The AirTAC AirTAC SDA80X160B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 160mm 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 SDA80X160B is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth compared to conventional round-body actuators. This specific configuration includes a male M22x1.5 piston rod end for secure mechanical coupling to your load.
Because the 160 mm stroke exceeds the 130 mm standard maximum for this 80 mm bore, this unit is classified as non-standard and supplied as a made-to-order item. The bore is hard-anodized and relies on a fixed NBR bumper at each end to decelerate the stroke. Note that this SKU lacks a piston magnet, so it cannot support magnetic sensing without upgrading to the -S variant.

Provides the heavy 2513.3 N push force required to eject dense plastic parts from moulding machines, utilizing the male M22x1.5 thread for rigid mounting to the ejector plate.
Handles vertical lifting of heavy product layers in end-of-line packaging, where the compact riveted body minimizes the vertical space consumed by the lift mechanism.
Drives heavy material blanks into a mechanical press, taking advantage of the 160 mm stroke to clear the feed path while relying on the fixed NBR bumper to absorb the end stop.
When sizing your system, consider stepping down to the SDA63, which provides 1558.6 N of push at 0.5 MPa, or moving up to the SDA100, which yields 3927 N at the same pressure. For this 80 mm bore, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa push force), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a plain actuator will not hold a load if air pressure drops or the valve is centered; the piston will drift. For suspended or vertical loads, integrate an external rod lock or a pilot-operated check valve.
To order correctly, confirm the 80 mm bore, the 160 mm non-standard stroke, and the PT3/8 port. This model includes the -B option, meaning it has a male M22x1.5 rod thread instead of the default female M14x1.5. It operates at speeds between 30 and 500 mm/s.
Quick checklist
This double-acting 80 mm bore cylinder provides a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this specific SKU does not have a piston magnet, so it cannot support reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, it uses a fixed NBR bumper to decelerate at stroke ends, not an adjustable air cushion. For high-energy or high-speed cycles, you should add an external shock absorber.
