The AirTAC Airtac SC32 Standard Cylinder SC32X450H is a genuine double-acting standard air cylinder with a Ø32mm bore and 450mm stroke, PT1/8 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC32X450H is a double-acting pneumatic cylinder delivering 402 N of push force at 0.5 MPa, making it a compact workhorse for light automation tasks. Its 12 mm diameter piston rod and 21 mm adjustable air cushion provide smooth end-of-stroke deceleration, while the Viton (FKM) seals extend the operating temperature range to 0–150 °C for hot-environment duty.
With a 450 mm stroke and a body length of 140 mm, this tie-rod cylinder suits applications needing a moderate reach in a confined space. The PT1/8 port and M10x1.25 rod thread ensure straightforward pneumatic connections, and the genuine AirTAC build guarantees reliable cycling in continuous production settings.

Related variants: SCD (double rod), SCJ (adjustable stroke), SCT (multi-position). Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
Viton seals allow this cylinder to operate in autoclave loading, drying ovens, or sterilisation tunnels where ambient temperatures reach up to 150 °C.
The 402 N push force at 0.5 MPa is ideal for ejecting lightweight plastic or metal components from injection moulds or stamping dies on a fast cycle.
Use the 450 mm stroke to pivot a small diverter gate on a packaging or sorting conveyor, directing products between lanes with clean pneumatic power.
Choose the SC32 when your application needs up to 402 N at 0.5 MPa; if you require more force, step up to the SC40 bore which provides 628 N at the same pressure. For strokes of 300 mm or longer, like this 450 mm unit, be mindful of side loads—a 12 mm rod can bend under off-axis force, so use an external linear guide or rod-alignment coupler to protect the bearing and seals.
To replace an existing cylinder, match five points: 32 mm bore, 450 mm stroke, PT1/8 port thread, basic (no bracket) mounting, and the absence of a magnet. This model uses high-temperature Viton seals, so confirm the seal material if the original ran in an elevated-temperature environment.
Quick checklist
At the maximum operating pressure of 0.9 MPa, the cylinder delivers 724 N of push force. At the standard 0.5 MPa, it provides 402 N push and 345 N pull.
No. The SC32X450H is a double-acting cylinder and will not hold position when pressure is exhausted or the valve is centred. For load holding without live pressure, you must add an external rod lock or a pilot-operated check valve.
