The AirTAC AirTAC SDA80X50BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm 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 SDA80X50BH is a double-acting single-rod compact cylinder engineered for heavy-duty operations within a minimal axial footprint. It delivers a substantial 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. By utilizing a short riveted body assembly rather than a conventional round-body design, this unit significantly reduces mounting depth where space is tightly constrained. The 80 mm bore features a hard-anodized inner wall and a robust 25 mm piston rod.
This specific configuration includes a male M22x1.5 threaded rod end for secure mechanical coupling to your load. It also incorporates fluororubber (FKM) seals for enhanced resistance to higher temperatures and oily environments. Instead of an adjustable air cushion, the piston strikes a fixed NBR bumper at each end of the stroke to decelerate the load. Note that this SKU lacks a piston magnet and therefore cannot support magnetic sensing.

Drives heavy stamping dies and holding fixtures where the 2513.3 N push force securely positions steel panels before the main press cycles.
Actuates heavy redirect gates on high-throughput packaging lines, utilizing the 50 mm stroke and FKM seals to withstand demanding duty cycles.
Pushes thick molded plastic parts out of heavy tooling, taking advantage of the rigid 25 mm rod and space-saving riveted body to fit tight mold bases.
When sizing this 80 mm bore model, consider stepping down to the SDA63 which provides 1558.6 N of push at 0.5 MPa, or stepping up to the SDA100 which yields 3927 N at the same pressure. The SDA80X50BH offers a computed safe working load of approximately 1508 N (about 60% of its 0.5 MPa rating) and a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match this exact specification: 80 mm bore, 50 mm stroke, PT3/8 port, male M22x1.5 rod thread, FKM seals, and no sensor magnet. Keep in mind that a plain compact cylinder like this does not hold its position if air pressure is lost; the piston will drift and the fixed bumper only decelerates it near the stroke end. For applications requiring a held load, an external rod lock or pilot-operated check valve is required.
Quick checklist
The SDA80X50BH generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push is 513 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept AirTAC reed or electronic switches. You would need the SDA80X50SBH variant for sensing capabilities. Additionally, it uses a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers are recommended for high-energy loads.
