The AirTAC SDA80X65BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 65mm 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 SDA80X65BH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 2513.3 N push force at 0.5 MPa. This specific SKU includes a male M22x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 80 mm bore features a hard-anodized inner wall and operates on a PT3/8 port at speeds between 30 and 500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Because this configuration omits the -S magnet code, it cannot host reed or electronic switches directly.

Drives the ejector pins on a 200-ton injection molding machine, utilizing the 2513.3 N extend force to strip plastic parts from the mold cavity efficiently.
Acts as the primary press ram in a CNC press brake for 4mm steel sheets, where the male M22x1.5 rod threads securely into the upper tooling die holder.
When sizing this actuator, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or moving up to the SDA100, which yields 3927 N at the same pressure. To finalize your order, confirm the 80 mm bore, 65 mm stroke, PT3/8 port, male M22x1.5 rod thread, and the FKM seal option.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the directional valve is centered. The fixed bumper only decelerates the piston near the stroke limits and does not function as a locking brake; if your application demands strict position holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore cylinder exerts a push force of 2513.3 N and a pull force of 2267.8 N 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, with an operating pressure range of 0.15-1.0 MPa and a speed range of 30-500 mm/s.
No, this specific SKU lacks the internal piston magnet, so it cannot host AirTAC reed or electronic switches. You would need the -S variant for sensing capabilities. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable cushion, so external shock absorption is advised for high-speed operations.
