The AirTAC AirTAC SDA80X110SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 110mm 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 SDA80X110SB is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, operating efficiently between 0.15 and 1.0 MPa. The riveted body design significantly reduces mounting depth compared to conventional round-body units, making it highly effective for machinery where space is strictly limited.
This specific configuration includes a built-in piston magnet (-S) for position detection using an AirTAC reed or electronic switch, and a male-thread piston rod (-B) sized at M22x1.5 for secure mechanical load coupling. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. For high-velocity cycles, an external shock absorber is advised to prevent impact damage.

Drives the ejector pins on a mid-tonnage injection molding machine, utilizing the 2513.3 N extend force to reliably strip finished plastic parts from the tool cavity.
Raises heavy product layers during automated palletizing, where the 128.1 kg vertical lift margin and 110 mm stroke provide the precise elevation needed for layer placement.
Actuates the heavy-duty clamping mechanism on a metal press brake, using the male M22x1.5 rod end to secure upper tooling safely during high-force bending operations.
Selecting this 80 mm bore model provides a theoretical maximum push capacity of 513 kgf at 1.0 MPa. When sizing your application, you can step down to the SDA63 which yields 1558.6 N of push force at 0.5 MPa, or step up to the SDA100 which provides 3927 N at the same pressure. Based on the 2513.3 N push figure at 0.5 MPa, the computed safe working load is approximately 1508 N (about 60 percent of capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed NBR bumper only decelerates near the stroke end rather than locking the load. If your application requires static holding, an external rod lock or pilot-operated check valve is necessary. To order, confirm the 80 mm bore, 110 mm stroke, PT3/8 port, built-in magnet, and male M22x1.5 rod thread.
Quick checklist
This 80 mm bore cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push capacity is 513 kgf when operated at the 1.0 MPa pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. Additionally, it does not feature a locking mechanism; if air is lost, the piston drifts and requires an external rod lock or pilot-operated check valve to hold position.
