The AirTAC AirTAC SDA80X120B 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 SDA80X120B is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. By utilizing a short riveted body assembly, it drastically reduces axial mounting depth compared to traditional round-body units, saving valuable machine footprint in tight assemblies. This specific configuration includes a male-thread piston rod end (M22x1.5) for secure mechanical load coupling.
This model relies on a fixed NBR bumper at each end to decelerate the piston near stroke completion. Because it lacks an adjustable air cushion, high-energy cycles may require an external shock absorber or a slowed approach speed. Furthermore, this SKU is supplied without a piston magnet, meaning it cannot host AirTAC reed or electronic switches for position sensing.

Drives heavy spot-welding guns on automotive assembly lines, utilizing the 2513.3 N extend force to maintain firm electrode pressure during the weld cycle.
Raises and lowers heavy product layers in end-of-line palletizing equipment, where the 128.1 kg vertical lift capacity handles substantial payload weights securely.
Actuates large mechanical arms in corrugated box sealing machinery, relying on the male M22x1.5 rod thread to attach robust folding and pressing fixtures.
When sizing your actuator, stepping down to the SDA63 yields 1558.6 N of push force at 0.5 MPa, while moving up to the SDA100 provides 3927 N. The SDA80X120B strikes a middle ground, offering a safe working load of roughly 1508 N (about 60% of its 0.5 MPa output) and a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 120 mm stroke, PT3/8 porting, and the male M22x1.5 rod thread.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the directional valve is centered. The piston will drift, and the fixed bumper only decelerates the stroke end without acting as a lock. If your application demands strict load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 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 on filtered air between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support AirTAC reed or electronic switches. You would need to specify the -S option code to add a magnet for position sensing. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion, so external shock absorption is recommended for high-speed operations.
