The AirTAC AirTAC SDA80X75BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 75mm 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 SDA80X75BH is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatics within tight axial envelopes. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, it significantly reduces overall mounting depth compared to conventional round-body units. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, with a theoretical maximum output of 513 kgf at 1.0 MPa.
This specific SKU includes a male M22x1.5 threaded piston rod end for robust mechanical coupling to your load, alongside an FKM (fluororubber) seal variant for enhanced thermal and oil resistance. The unit operates at 30-500 mm/s, relies on a fixed NBR bumper at each end to decelerate the stroke, and lacks a piston magnet. Because it is not equipped with the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Ejects heavy stamped metal sheets from press dies, utilizing the 2513.3 N extend force and the 75 mm stroke to positively clear the lower mold half.
Raises loaded pallets in compact packaging lines where axial space is restricted, safely handling loads near the 128.1 kg vertical lift threshold.
Secures intermediate injection mold platens, taking advantage of the FKM seals for high-temperature molding environments and the male M22x1.5 rod for rigid mounting.
When sizing this 80 mm actuator, consider stepping down to the SDA63 which yields 1558.6 N push at 0.5 MPa, or moving up to the SDA100 which provides 3927 N push at 0.5 MPa. Based on the 2513.3 N output at 0.5 MPa, the computed safe working load is approximately 1508 N (60% capacity), translating to a vertical lift capability of about 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match this configuration: 80 mm bore, 75 mm stroke, PT3/8 port, male M22x1.5 rod thread, FKM seals, and no sensor magnet. Note that a plain 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. If your application demands position holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting cylinder provides 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, handles a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
No, this model uses a fixed NBR bumper at each end to decelerate the stroke end, which is not a field-adjustable air cushion. For high-energy cycles, you should add an external shock absorber. Additionally, this SKU lacks the -S magnet, so it cannot support AirTAC reed or electronic switches.
