The AirTAC Airtac SC40 Standard Cylinder SC40X260SH is a genuine double-acting standard air cylinder with a Ø40mm bore and 260mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X260SH is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa), built for high-temperature automation. Its 16 mm diameter piston rod and 21 mm adjustable air cushion provide reliable deceleration across the 260 mm stroke.
This model includes a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, eliminating external brackets. The Viton (-H) seal package shifts the operating range to 0–150 °C, making it suitable for autoclaves, drying lines, and foundry equipment where standard 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.
Viton seals withstand 150°C continuous operation, making this cylinder ideal for actuating platens in hot presses, composite molding, and rubber curing where radiant heat would destroy standard seals.
The FKM seal material resists steam and high-temperature washdown. Use the SC40X260SH for door actuation or product handling inside sterilizers, autoclaves, and clean-in-place systems.
With 628 N of force at 0.5 MPa and a 260 mm stroke, this cylinder diverts or stops products on conveyor lines passing through industrial dryers and curing ovens without seal failure.
For higher force, step up to the 50 mm bore SC50 series which provides 982 N at 0.5 MPa. If space is tight and 402 N is sufficient, the 32 mm bore SC32 series is a compact alternative. This 260 mm stroke is within the 1200 mm maximum standard stroke for 40 mm bore SC cylinders.
To ensure a safe mechanical replacement, match five points: 40 mm bore, 260 mm stroke, PT port thread, the built-in magnet (-S) for sensor compatibility, and the Viton seal material for high-temperature operation. For strokes over 300 mm, always evaluate side-load conditions on the 16 mm rod; an external guide or guided cylinder is recommended to prevent rod bending under lateral forces.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force on the retract stroke is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The SC series is a tie-rod cylinder and its body length (142 mm body + stroke) is shorter than an equivalent ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. It directly replaces another AirTAC SC40 cylinder with the same bore, stroke, PT ports, magnet option, and Viton seals.
