The AirTAC SDA80X160 Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 160mm 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 SDA80X160 is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. This specific configuration features an 80 mm bore and a 160 mm stroke.
Because the 160 mm stroke exceeds the 130 mm maximum standard stroke for this bore size, this unit is classified as non-standard and produced 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 fixed NBR bumpers rather than adjustable air cushions. This SKU is supplied without a piston magnet, meaning it cannot host magnetic position sensors.

Drives the ejection plate inside a large plastic injection molding machine, utilizing the 2513.3 N push force to reliably strip heavy automotive interior panels from the tool cavity.
Acts as a rugged back-gauge stopper in a sheet metal fabrication line, holding thick steel plates firmly in position prior to bending operations.
When sizing this actuator, evaluate your force requirements carefully: stepping down to the SDA63 provides 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 yields 3927 N. To finalize your order, confirm the 80 mm bore, 160 mm non-standard stroke, PT3/8 port, female M14x1.5 rod-end thread, and the absence of a magnet.
Keep in mind that a standard double-acting cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end; it does not function as a locking brake. If your application demands secure load holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting 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 between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
This specific SKU lacks the internal piston magnet, so it cannot accept reed or electronic switches. You would need the -S option for position sensing. Additionally, it uses fixed NBR bumpers to decelerate at stroke ends, not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
