The AirTAC SDA80X45SBH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 45mm 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 SDA80X45SBH is a double-acting single-rod compact cylinder engineered for high-force tasks in tight footprints. Delivering a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa, it utilizes a short riveted body that significantly reduces axial mounting depth compared to conventional round-body units. This specific configuration includes a male M22x1.5 piston rod end, a built-in magnetic piston for position sensing, and high-temperature fluororubber (FKM) seals.
The 80 mm bore features a hard-anodized inner wall and operates on PT3/8 ports 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 external shock absorbers should be added for high-energy cycles. Grooves around the body accept AirTAC reed or electronic switches to track the piston position.

Drives heavy ejector pins on a 150-ton injection molding press where the 2513.3 N extend force clears dense plastic parts within a confined machinery cell.
Raises heavy steel coil blanks into a progressive die feeder, relying on the 45 mm stroke and FKM seals to withstand elevated ambient shop heat.
Actuates a robust spot-welding gun arm on an automotive body-in-white line, using the male M22x1.5 rod thread to secure the heavy copper tip holder.
When sizing this 80 mm bore unit, 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 order, confirm the 80 mm bore, 45 mm stroke, PT3/8 port, male M22x1.5 rod thread, magnet, and FKM seal options. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, the push is 3518.6 N and the pull is 3175 N. The theoretical maximum push force is 513 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed operations, you should add external shock absorbers. Because it includes the -S option, it has a built-in magnet compatible with AirTAC reed or electronic switches mounted in the body grooves.
