The AirTAC AirTAC SDA80X40BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 40mm 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 SDA80X40BH is a double-acting, single-rod compact cylinder engineered to deliver substantial force within a minimal axial footprint. Utilizing a short riveted body assembly, it conserves valuable mounting depth in tight machinery layouts where conventional round-body units simply cannot fit. At 0.5 MPa, this 80 mm bore unit generates 2513.3 N of push force and 2267.8 N of pull force, while safely handling a working load of roughly 1508 N for a 2:1 design margin.
This specific SKU is configured with a male M22x1.5 piston rod thread (denoted by the B option) for robust mechanical coupling to your load. It also includes fluororubber (FKM) seals (the H option) for enhanced thermal stability and oil resistance compared to standard NBR. The end caps rely on a fixed NBR bumper to decelerate the piston near stroke end, which is not an adjustable air cushion. Because this variant lacks the S magnet code, it cannot host reed or electronic switches.

Drives heavy mold ejector pins in plastic injection machinery where the 2513.3 N extend force reliably strips finished parts from tight tooling cavities.
Indexes thick sheet metal stock into progressive stamping presses, utilizing the 25 mm male-threaded rod to push heavy material feeds accurately.
Raises loaded pallets in high-temperature packaging zones, leveraging the FKM seals to withstand ambient heat while lifting approximately 128 kg payloads.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down to the SDA63 reduces the 0.5 MPa push capacity to 1558.6 N, whereas stepping up to the SDA100 increases it significantly to 3927 N. This SDA80X40BH configuration features a 40 mm stroke, PT3/8 air ports, a male M22x1.5 rod end, and FKM seals. Note that a standard double-acting cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift. For vertical lifts of approximately 128.1 kg, incorporate an external rod lock or pilot-operated check valve to secure the payload safely.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, or 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30 to 500 mm/s.
No, this specific SKU lacks the S option, meaning it has no piston magnet and cannot accept reed or electronic switches. Additionally, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; for high-energy cycles, you should add an external shock absorber.
