The AirTAC AirTAC SDA80X30SN Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm 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 SDA80X30SN is a double-acting, single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted body assembly significantly reduces axial mounting depth, providing a highly space-efficient footprint for machinery where a standard round-body unit would be too bulky. The 80 mm bore features a hard-anodized inner wall and a 25 mm piston rod for high structural integrity.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, enabling precise end-of-stroke detection via the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Drives the ejection plate of a 200-ton injection molding machine, utilizing the 2513.3 N push force to reliably strip finished plastic parts from the core within a confined press footprint.
Acts as a holding clamp in a sheet metal stamping die, where the short 30 mm stroke and fixed NBR bumpers absorb the rapid end-stop impact during high-speed press cycling.
Provides vertical elevation for heavy palletized loads in a compact packaging cell, lifting up to 128.1 kg with a 2:1 safety factor while the built-in magnet confirms the raise position.
When sizing this unit, evaluate your force requirements carefully: stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while upgrading to the SDA100 provides 3927 N. The SDA80X30SN offers a computed safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating) and a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin. To confirm your ordering essentials: specify the 80 mm bore, 30 mm stroke, PT3/8 port, built-in magnet, and female M14x1.5 rod-end thread.
Keep in mind that a standard compact cylinder does not hold its 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 demands strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push 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, the SDA80X30SN relies on a fixed NBR bumper at each end to absorb impact. It is not equipped with an adjustable air cushion, nor does the bumper function as a braking lock. For high-speed or high-energy loads, you should slow the approach speed or install an external shock absorber to prevent premature wear.
