The AirTAC AirTAC SDA32X45SB 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 SDA32X45SB 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 body assembly significantly reduces axial mounting depth compared to conventional round-body units, making it ideal for machinery where space savings are critical. The unit includes a built-in piston magnet for position sensing and a male M10x1.25 threaded rod end for secure load coupling.
This model features a 12 mm piston rod and a PT1/8 port. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Magnetic-switch grooves encircle the hard-anodized aluminum body, allowing you to mount an AirTAC reed or electronic switch directly along the stroke path.

Actuates the cutting tool carriage on an electronic depaneling machine, utilizing the 45 mm stroke and male M10x1.25 rod end for precise board separation.
Folds minor corrugated box flaps on a continuous packaging line, where the short riveted body minimizes axial footprint within the tight conveyor framework.
Positions the metal sheet backstop on a light-duty CNC press brake, relying on the 402.1 N push force to maintain alignment against the material.
When sizing this unit, stepping down to an SDA25 yields 245.4 N of push force at 0.5 MPa, while stepping up to an SDA40 provides 628.3 N at the same pressure. For this 32 mm bore, the safe working load is approximately 241 N (about 60% of the 402.1 N figure), translating to a vertical lift capacity of roughly 20.5 kg with a 2:1 safety margin. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock. For applications requiring suspended load holding, incorporate an external rod lock or a pilot-operated check valve. To order, confirm the 32 mm bore, 45 mm stroke, PT1/8 port, built-in magnet (S), and male-thread rod end (B).
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 and the pull force is 483.8 N. The theoretical maximum push force is 82 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion. For high-speed or high-energy cycles, add an external shock absorber. Because this model includes the -S magnet, you can install an AirTAC reed or electronic switch into the body grooves for position detection.
