The AirTAC 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.
Raises 120 kg paper product pallets in a packaging line, operating safely within the 128.1 kg vertical lift capacity calculated at a 2:1 safety margin.
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. For the SDA80X65BH, the computed safe working load is approximately 1508 N (about 60% of its 0.5 MPa capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. 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.
