The AirTAC AirTAC SDA80X140B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 140mm 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 SDA80X140B is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted body assembly merges the barrel, rear cover, piston, and rod to drastically reduce axial mounting depth, offering a highly space-efficient footprint where a conventional round-body unit would simply not fit. This specific SKU features a male M22x1.5 threaded piston rod end for robust mechanical coupling to your load.
Because the 140 mm stroke exceeds the 130 mm maximum standard stroke for an 80 mm bore, this unit is classified as non-standard and supplied as a made-to-order item. The bore is hard-anodized and uses a two-way piston seal, while end-stop deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. Note that this configuration omits the piston magnet, so it cannot directly host AirTAC reed or electronic switches.

Drives heavy mold ejection plates in plastic injection machinery where the male M22x1.5 rod end secures the tooling and the short riveted body minimizes press interference.
Lifts loaded pallets in packaging lines, utilizing the 2513.3 N push force to elevate 128 kg loads vertically with a 2:1 safety margin during transfer operations.
Advances thick metal stock into mechanical stamping presses, requiring the fixed NBR bumper to absorb high kinetic energy at the end of the 140 mm traverse.
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to the SDA63 yields 1558.6 N, while stepping up to the SDA100 provides 3927 N. Based on the 0.5 MPa output, the safe working load is approximately 1508 N (about 60% of capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 140 mm non-standard stroke, PT3/8 port, and the male M22x1.5 rod thread.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure is lost or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your application requires suspended load security, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore cylinder uses a PT3/8 air port. It generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
No, end-of-stroke deceleration relies solely on a fixed NBR bumper, which is not a field-adjustable air cushion; for high-speed cycling, add an external shock absorber. Additionally, this SKU lacks the -S piston magnet, so it cannot support reed or electronic switches without changing to the magnetized variant.
