The AirTAC Airtac SC32 Standard Cylinder SC32X75H is a genuine double-acting standard air cylinder with a Ø32mm bore and 75mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X75H is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, equipped with a 12 mm diameter piston rod and PT1/8 ports. This model delivers a push force of 402 N at 0.5 MPa and 724 N at the maximum operating pressure of 0.9 MPa, making it suitable for light automation tasks.
With a 75 mm stroke and a compact body length A of 140 mm, this cylinder fits well in confined spaces. The 'H' suffix specifies a Viton (FKM) piston seal, which shifts the operating temperature range to 0 to +150 °C, making it a reliable choice for applications involving elevated ambient heat where standard TPU seals would degrade.

The Viton seals enable reliable operation in autoclaves, drying ovens, or near heated platens where ambient temperatures reach up to 150 °C, preventing premature seal failure.
With a 75 mm stroke and 724 N of force at 0.9 MPa, this cylinder is ideal for ejecting small plastic or metal components from molds or pick-and-place nests.
Use the SC32X75H for actuating small heated dies or sealing jaws in packaging machinery, where the combination of compact size and high-temperature tolerance is critical.
Select the SC32X75H for light clamping, sorting, or ejecting tasks where the 402 N push force at 0.5 MPa is sufficient. If your application requires more force, consider stepping up to the 40 mm bore SC40 series, which provides 628 N at the same pressure. Always ensure the rod is aligned with the load axis; for strokes over 300 mm, an external guide is recommended to prevent rod bending from side loads.
When replacing an existing cylinder, confirm five key points for a direct fit: the 32 mm bore, 75 mm stroke, PT1/8 port thread, basic mounting (no accessories), and the absence of a built-in magnet. This Viton-sealed model is specifically for high-temperature environments up to 150 °C.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 402 N. The force increases to 563 N at 0.7 MPa and reaches a maximum of 724 N at 0.9 MPa. The theoretical maximum at 1.0 MPa is 82 kgf.
Yes, the Viton seal in the SC32X75H works perfectly at room temperature. Its 0 to 150 °C range simply adds high-temperature capability. It is a direct replacement for a standard SC32X75 if your environment requires FKM seals.
