The AirTAC AirTAC SDA80X20SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 20mm 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 SDA80X20SB is a double-acting, single-rod compact cylinder engineered for high-force tasks in tight axial spaces. It delivers a robust 2513.3 N push and 2267.8 N pull at 0.5 MPa, providing substantial thrust within a short riveted body footprint. The integrated piston magnet enables position detection, while the male M22x1.5 rod end simplifies direct mechanical coupling to heavy loads.
Designed without adjustable air cushions, this unit relies on a fixed NBR bumper at each end to absorb end-stop impact. The hard-anodized 80 mm bore operates efficiently between 30-500 mm/s. Because the bumper only decelerates the piston near the stroke terminus, high-energy cycles may require an external shock absorber to prevent mechanical wear.

Drives short-stroke ejection pins on a 200-ton injection molding press, utilizing the 2513.3 N extend force to break heavy plastic parts free from the mold cavity.
Positions back-gauge stops on a CNC press brake, where the short 20 mm stroke and male M22x1.5 rod provide rigid, high-thrust positioning of sheet metal blanks.
Applies a compact 128.1 kg holding force to stabilize unstable pallet loads during stretch wrapping, fitting neatly into the machine's vertical gantry space.
When sizing this 80 mm bore actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N push at 0.5 MPa; stepping up, the SDA100 yields 3927 N. For this SDA80X20SB configuration, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 20 mm stroke, PT3/8 port, built-in magnet (S), and male M22x1.5 piston rod (B). Remember that a standard compact cylinder drifts when air pressure is lost or the valve is centered, so install an external rod lock or pilot-operated check valve if your application demands strict position holding.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 2513.3 N push and 2267.8 N pull. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push force is 513 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a locking brake. The built-in magnet (-S) allows tracking via AirTAC reed or electronic switches mounted in the body grooves. For high-speed operations, adding an external shock absorber is advised.
