The AirTAC AirTAC SDA80X25SBH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 25mm 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 SDA80X25SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within confined axial spaces. Utilizing a riveted body design, it achieves a remarkably short mounting footprint compared to conventional round-body units, delivering a robust 2513.3 N push force at 0.5 MPa. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male M22x1.5 threaded piston rod (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance.
The 80 mm bore features a hard-anodized inner wall and operates on PT3/8 ports at speeds between 30 and 500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. For high-speed cycling, operators should incorporate external shock absorbers or regulate the approach velocity to mitigate mechanical stress.

Provides the 2513.3 N push force required to eject heavy stamped metal panels from progressive dies, utilizing the short 25 mm stroke to minimize machine footprint.
Lifts lower pallet layers in high-throughput packaging lines, where the FKM seals withstand elevated ambient heat and the male M22x1.5 rod secures heavy lifting platens.
Secures core inserts in plastic injection molding machinery, relying on the magnetic piston for immediate position feedback via reed or electronic switches.
Selecting this 80 mm bore yields a 2513.3 N push at 0.5 MPa, with a computed safe working load of roughly 1508 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity near 128.1 kg using a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 provides 1558.6 N at 0.5 MPa; conversely, escalating to the SDA100 offers 3927 N at 0.5 MPa for heavier payloads. When ordering, confirm the 25 mm stroke, PT3/8 port, male M22x1.5 rod end, the integrated magnet, and the FKM seal option. Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered—the fixed bumper only decelerates near the stroke end and does not function as a locking brake, so an external rod lock or pilot-operated check valve is necessary for fail-safe load holding.
Quick checklist
This double-acting 80 mm bore cylinder generates 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, has a proof pressure of 1.5 MPa, and functions in temperatures from -20 to +70 C.
It relies on a fixed NBR bumper at each end to decelerate the piston near the stroke limits; this is not an adjustable air cushion, so external shock absorbers are recommended for high-energy cycles. The built-in magnet (-S) allows you to mount AirTAC reed or electronic switches directly into the body grooves for precise position detection.
