The AirTAC AirTAC SDA80X85SB Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 85mm 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 SDA80X85SB is a double-acting single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted body assembly drastically reduces axial mounting depth compared to conventional round-body units, making it highly effective for machinery where space footprint is critical. The 80 mm bore features a hard-anodized inner wall and a two-way piston seal for extended operational life.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, and a male-thread piston rod (-B) sized at M22x1.5 for secure mechanical load coupling. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should add external shock absorbers if cycling at the maximum 500 mm/s speed.

Provides the high 2513.3 N extension force needed to knock finished plastic parts off large injection molding tooling, utilizing the 85 mm stroke within a tight press cavity.
Deploys the male M22x1.5 threaded rod to push and align thick sheet metal blanks against a backgauge on a heavy-duty press brake before the bending cycle begins.
Handles vertical lifting of heavy industrial pallets, relying on the compact riveted body to fit within tight conveyor transfer zones without sacrificing lifting power.
When sizing this 80 mm bore unit, stepping down to the SDA63 yields 1558.6 N of push force at 0.5 MPa, while stepping up to the SDA100 provides 3927 N at the same pressure. Based on the 2513.3 N output at 0.5 MPa, a safe working load is approximately 1508 N (about 60% capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end without locking the load; an external rod lock or pilot-operated check valve is required to hold a vertical load safely.
To order, confirm the 80 mm bore, 85 mm stroke, PT3/8 port, the required -S magnet for position sensing, and the -B male M22x1.5 rod thread.
Quick checklist
This 80 mm bore model uses a PT3/8 air port. It generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston near stroke end. It is not an adjustable air cushion, so for high-energy or high-speed cycles, you should add an external shock absorber or slow the approach speed.
