The AirTAC AirTAC SDA80X120S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 120mm 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 SDA80X120S is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within confined axial footprints. Utilizing a riveted assembly that merges the barrel, rear cover, and piston, it achieves a remarkably short overall length compared to conventional round-body units. At 80mm, this bore generates a substantial 2513.3 N push force at 0.5 MPa, scaling to 3518.6 N at 0.7 MPa.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. The 25mm piston rod features an M14x1.5 female thread, while the PT3/8 air port ensures high flow for the 120mm stroke. End-stopping relies on a fixed NBR bumper rather than an adjustable cushion, effectively decelerating the load near stroke termination without adding bulk.

Provides robust 2513.3 N push force to eject heavy formed metal panels from stamping dies, where the short riveted body minimizes interference with the press tooling.
Lifts layered product loads up to 128 kg on packaging lines, utilizing the 120mm stroke to raise goods between conveyor tiers before the pallet descends.
Drives the separation of large molded plastic components from heavy tooling, relying on the 25mm rod to absorb side-load-free extraction forces.
When sizing this 80mm bore, compare its 2513.3 N push at 0.5 MPa against adjacent options: the SDA63 provides 1558.6 N, while the SDA100 offers 3927 N. For this model, a safe working load is approximately 1508 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of about 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80mm bore, 120mm stroke, PT3/8 port, female rod thread, and the required -S magnet.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The fixed NBR bumper only decelerates the piston near the stroke ends and does not function as a locking brake. If your application must hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80mm bore double-acting cylinder outputs 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston near stroke completion; this is not an adjustable air cushion, so high-speed applications may need external shock absorbers. The -S option includes a piston magnet compatible with AirTAC reed or electronic switches mounted in the body grooves.
