The AirTAC AirTAC SDA32X150S Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 150mm 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 SDA32X150S is a double-acting, single-rod compact cylinder featuring a 32mm bore and a 150mm stroke. It delivers a push force of 402.1 N and a pull force of 345.6 N at 0.5 MPa. The riveted body design significantly reduces axial mounting depth compared to round-body units, saving valuable machine footprint. Because this 150mm stroke exceeds the 130mm standard maximum for this bore size, it is manufactured as a made-to-order unit.
This model includes a built-in piston magnet (-S) for use with AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable cushion. Operating speed ranges from 30-500 mm/s, and the 12mm piston rod uses an M6x1.0 female thread end.

Routes parcels on logistics sorting lines by extending 150mm to nudge cartons from the main belt, utilizing the 402.1 N push force to overcome box inertia.
Pushes assembled printed circuit boards out of a testing fixture, where the compact riveted body minimizes the required rear clearance behind the machine.
Actuates a guiding arm on a packaging web line, using the built-in magnet and an electronic switch to confirm the 150mm extension for roll alignment.
When sizing this unit, stepping down to the SDA25 yields 245.4 N push at 0.5 MPa, while stepping up to the SDA40 provides 628.3 N. For this 32mm bore, a safe working load is approximately 241 N (about 60% of the 402.1 N figure), allowing a vertical lift of roughly 20.5 kg with a 2:1 safety margin. Ensure you specify the PT1/8 port, the female rod thread, and the required magnetic sensor when ordering.
Note that a plain SDA cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near the end and does not act as a locking brake. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 402.1 N and the pull force is 345.6 N. At 0.7 MPa, the push force is 563 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
No, the SDA series uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow down the approach speed.
