The AirTAC AirTAC SDA32X30SBH Compact Cylinder | 32mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø32mm bore and 30mm 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 SDA32X30SBH is a double-acting, single-rod compact cylinder engineered for tight machinery footprints. Its riveted assembly minimizes axial mounting depth while delivering 402.1 N of push force at 0.5 MPa. This specific configuration includes a male M10x1.25 piston rod thread for secure mechanical coupling and an FKM fluororubber seal for enhanced thermal and oil resistance.
The 32 mm bore features a hard-anodized inner wall and a fixed NBR bumper at each end to absorb end-stop impact. Because this unit carries the -S option, a built-in piston magnet enables position detection via an AirTAC reed or electronic switch mounted in the body grooves. The PT1/8 air port feeds a 12 mm rod, yielding a safe working load around 241 N (roughly 60% of the 0.5 MPa output) for reliable actuation.

Thread: PT standard. Related SDA-family variants: SSA (single-acting push), STA (single-acting pull), SDAD (double rod), SDAJ (adjustable stroke), SDAT (duplex), SDAW (duplex-end).
Secures aluminum housings during machining. The 402.1 N extend force holds parts firmly against locators, while the FKM seals resist way-oil contamination.
Drives mechanical arms to tuck corrugated flaps on automated box erecting lines. The short 30 mm stroke and compact depth fit within tight transfer gantries.
Positions fluid dispense needles over microplates. The male M10x1.25 rod end mounts custom tooling, and the -S magnet triggers an electronic switch for precise shot timing.
When sizing this actuator, compare its 402.1 N push at 0.5 MPa against adjacent bores: stepping down to the SDA25 yields 245.4 N, while stepping up to the SDA40 provides 628.3 N. This SDA32X30SBH variant includes the -S magnet, -B male M10x1.25 rod, and -H FKM seals, alongside the standard PT1/8 port. Verify your stroke length falls within the 130 mm standard limit for this bore.
Keep in mind that a standard compact cylinder drifts when air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the piston near the stroke end and does not function as a locking brake. If your application must hold a vertical load of 20.5 kg without live pressure, 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 is 563 N and the pull is 483.8 N. The theoretical maximum push is 82 kgf at the 1.0 MPa operating pressure limit.
No. It uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it does not hold load without air; if pressure drops, the piston drifts. Use an external rod lock or pilot-operated check valve if position holding is required.
