The AirTAC Airtac SC32 Standard Cylinder SC32X250SH is a genuine double-acting standard air cylinder with a Ø32mm bore and 250mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC32X250SH is a double-acting tie-rod cylinder delivering 402 N of push force at 0.5 MPa (724 N at 0.9 MPa). With a 32 mm bore and 250 mm stroke, it uses a 12 mm diameter piston rod and M10x1.25 rod thread for compact, medium-cycle applications.
The -S suffix integrates a built-in magnet, allowing CMSG, DMSG, or EMSG reed and solid-state sensors to clamp directly onto the barrel for precise end-of-stroke detection. The -H suffix specifies Viton (FKM) seals, extending the operating temperature range to 0–150 °C, making this cylinder suitable for hot environments where standard TPU seals would degrade.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The Viton seals handle 0–150 °C, making this cylinder ideal for autoclave doors, drying ovens, or sterilisation equipment where standard seals would fail.
The built-in magnet enables CMSG/DMSG sensors to confirm extend and retract positions, perfect for small-part sorting gates or pick-and-place mechanisms.
At 250 mm stroke, the SC32X250SH can operate lightweight product diverters on narrow conveyors, with sensor feedback ensuring reliable cycle completion.
Choose the SC32 when space is tight and the 402 N push force at 0.5 MPa meets the load requirement. If you need more force, step up to the SC40 (628 N at 0.5 MPa). For strokes of 300 mm or longer, consider an external guide or a guided cylinder to protect the 12 mm rod from bending under side loads. When replacing an existing cylinder, match five points: 32 mm bore, 250 mm stroke, PT port thread, the built-in magnet (-S), and the Viton seal material (-H).
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 724 N.
Yes. The -H suffix denotes Viton (FKM) seals, rated for continuous operation from 0 to 150 °C. This is a key differentiator from the standard TPU seal version, which is limited to -20 to +70 °C.
