The AirTAC AirTAC SDA80X65SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 65mm 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 SDA80X65SB is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs, 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.
This specific configuration includes a built-in piston magnet (-S) for position detection via AirTAC reed or electronic switches seated in the body grooves, and a male M22x1.5 threaded piston rod (-B) for direct load coupling. The 25 mm hard-anodized piston rod is designed for short-stroke actuation, and end-stop deceleration is handled strictly by fixed NBR bumpers rather than adjustable air cushions. Operating speed ranges from 30-500 mm/s.

Drives heavy mold ejection plates in plastic injection machinery where the short riveted body minimizes interference with the press platen while delivering 2513.3 N of extend force.
Actuates heavy-duty pallet lift gates and material handling stops, utilizing the male M22x1.5 rod end to securely attach lifting forks without requiring additional adapters.
Pushes heavy metal blanks into stamping presses, relying on the 80 mm bore's robust 3518.6 N push at 0.7 MPa to overcome initial material friction in automated feed lines.
Selecting this 80 mm bore model provides a safe working load of roughly 1508 N (about 60% of the 2513.3 N push at 0.5 MPa), which translates to a vertical lift capacity 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 at 0.5 MPa. When ordering, confirm the 65 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the integrated magnet. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed NBR bumper only decelerates the stroke end rather than locking the load. For vertical or suspended loads, an external rod lock or pilot-operated check valve is required to prevent drifting.
Quick checklist
The SDA80X65SB generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 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, with a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
End stops are managed by fixed NBR bumpers that decelerate the piston near the stroke ends; these are not adjustable air cushions, so external shock absorbers are recommended for high-speed approaches. Additionally, the cylinder cannot hold a load if air pressure drops, as the bumpers only decelerate and do not act as a brake or rod lock.
