The AirTAC Airtac SC40 Standard Cylinder SC40X700H is a genuine double-acting standard air cylinder with a Ø40mm bore and 700mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X700H is a double-acting pneumatic cylinder with a 40 mm bore and 700 mm stroke, factory-equipped with high-temperature Viton (FKM) seals that extend the operating range to 0–150 °C. This model delivers 628 N of push force at 0.5 MPa and 1130 N at the maximum operating pressure of 0.9 MPa, making it suitable for hot-environment automation tasks.
Its 16 mm diameter piston rod and PT1/4 port ensure solid air flow, while the 21 mm adjustable air cushion at each end decelerates the load smoothly. The body length A is 142 mm, giving a total extended length of approximately 842 mm. This is a genuine AirTAC SC tie-rod cylinder, shorter than an ISO 15552 profile.

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 handle continuous 150°C environments like autoclave doors, drying ovens, or foundry knock-out stations where standard seals would fail.
Provides 1130 N of clamping force at 0.9 MPa for holding heated plastic sheets during the forming cycle, resisting heat soak from the tooling.
Operates in high-temperature washdown areas for pushing trays or diverting baked goods, with FKM seals compatible with aggressive cleaning regimes.
Choose the SC40X700H when your application needs a 40 mm bore with Viton seals for elevated temperatures up to 150 °C. If the 628 N push force at 0.5 MPa is marginal, stepping up to a 50 mm bore provides 982 N; if space is tight, the 32 mm bore offers 402 N. For this 700 mm stroke, ensure the rod is guided externally if any side load is present—an unsupported 16 mm rod at full extension is vulnerable to bending and seal wear. When replacing, match bore, stroke, PT port thread, and the Viton seal specification exactly.
Quick checklist
At 0.5 MPa the push force is 628 N and pull force is 528 N. At the maximum operating pressure of 0.9 MPa, push force reaches 1130 N. The theoretical maximum at 1.0 MPa is 128 kgf.
No. The SC40X700H is a double-acting cylinder and will drift or drop if pressure is exhausted. For load holding without live pressure, you must add a pilot-operated check valve or an external mechanical rod lock.
