The AirTAC AirTAC SDA80X20SBH 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 SDA80X20SBH is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within confined machinery envelopes. Utilizing a short riveted body assembly, it drastically reduces axial mounting depth compared to traditional round-body units, delivering a robust 2513.3 N push force at 0.5 MPa alongside a 20 mm stroke. This specific configuration includes a built-in piston magnet (-S) for position sensing, a male M22x1.5 piston rod thread (-B), and fluororubber (-H) seals for enhanced thermal and oil resistance.
Designed around a hard-anodized 80 mm bore, the unit operates at speeds between 30-500 mm/s and accepts PT3/8 air ports. End-of-travel deceleration is managed strictly by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. For high kinetic energy loads, operators should incorporate an external shock absorber or decelerate the approach speed to protect the 25 mm piston rod from side loading.

Drives short-stroke knockout pins in automotive plastics molding where the 2513.3 N extend force breaks parts free from tight tooling cavities.
Positions and holds thick sheet metal blanks within a progressive die set, utilizing the 80 mm bore capacity and FKM seals to withstand nearby heat.
Acts as a high-force physical stop block in end-of-line pallet routing, using the male M22x1.5 rod to securely mount a wear-resistant contact pad.
When sizing this 80 mm bore actuator, evaluate your force margins carefully: stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while upgrading to the SDA100 provides 3927 N. At 0.5 MPa, the SDA80X20SBH provides a safe working load of roughly 1508 N (about 60% of its 2513.3 N capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact configuration: 80 mm bore, 20 mm stroke, PT3/8 port, male M22x1.5 rod thread, FKM seals, and a magnetic piston for reed or electronic switches.
Remember that a standard compact cylinder does not hold its position if air pressure drops or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near the end points rather than locking the load. If your application requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in ambient temperatures from -20 to +70 C.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion, so high-speed applications may need external shock absorption. The -S code indicates a built-in magnet compatible with AirTAC reed or electronic switches mounted in the body grooves, and the -B code specifies a male M22x1.5 rod end.
