The AirTAC AirTAC SDA32X45S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 45mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA32X45S is a double-acting single-rod compact cylinder engineered to deliver 402.1 N of push force and 345.6 N of pull force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to minimize axial mounting depth, providing a distinct footprint advantage in tight machine bays. The 32 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable operation.
This specific configuration includes an integrated piston magnet (the S option) for direct compatibility with AirTAC reed or electronic switches, which seat neatly into the grooves around the body. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling. The unit connects via a PT1/8 port and drives the load using a 12 mm rod.

Secures aluminum engine blocks onto machining centers. The 402.1 N extend force provides rigid holding against cutting forces without occupying excessive vertical tooling space.
Drives mechanical arms to tuck corrugated box flaps prior to sealing. The 45 mm stroke and fixed NBR bumper ensure rapid, repeatable motion at line speeds up to 500 mm/s.
Actuates a routing diverter on a modular conveyor system. The integrated -S magnet triggers reed or electronic switches to confirm gate position for the PLC.
When sizing this actuator, evaluate your force margins both ways: stepping down to the SDA25 yields 245.4 N of push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. Based on the 402.1 N output at 0.5 MPa, the safe working load is approximately 241 N (about 60% capacity), translating to a vertical lift capability of roughly 20.5 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered; the fixed bumper only decelerates the stroke end rather than locking it, so an external rod lock or pilot-operated check valve is required for strict position holding. To order, confirm the 32 mm bore, 45 mm stroke, PT1/8 port, female M6x1.0 rod thread, and the built-in magnet.
Quick checklist
At 0.5 MPa, this 32 mm bore double-acting cylinder provides 402.1 N of push force and 345.6 N of pull force. At 0.7 MPa, the push increases to 563 N. The theoretical maximum push force is 82 kgf at the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed applications, you should add external shock absorbers. Because it includes the S option, it has a built-in magnet for AirTAC reed or electronic switches mounted in the body grooves.
