The AirTAC SC50 Standard Cylinder SC50X80SH is a genuine double-acting standard air cylinder with a Ø50mm bore and 80mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC50X80SH delivers 982 N of push force at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa, making it a robust mid-bore actuator for industrial automation. With an 80 mm stroke and a 20 mm piston rod, this double-acting cylinder provides a compact yet powerful linear motion solution.
This model is configured with a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG sensors, enabling precise, non-contact position sensing along the tie-rod barrel. The -H suffix specifies Viton (FKM) seals, which shift the operating temperature range from the standard -20 to +70 °C up to 0 to +150 °C, making it suitable for high-temperature or chemically aggressive environments.

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 allow this SC50X80SH to operate reliably in ambient temperatures up to 150°C, ideal for actuators near ovens, autoclaves, or foundry equipment where standard seals would fail.
The built-in magnetic piston enables easy clamping of reed or solid-state sensors (CMSG/DMSG/EMSG) to the barrel for precise end-of-stroke or mid-stroke position feedback in pick-and-place systems.
With 1767 N of force at 0.9 MPa, this cylinder is well-suited for diverting packages, actuating gates, or pushing products on a conveyor line, especially in washdown or heated zones.
For applications requiring more force, stepping up to the 63 mm bore (SC63 series) provides 1559 N of push at 0.5 MPa. If space is a constraint and less force is acceptable, the 40 mm bore (SC40 series) delivers 628 N at the same pressure. This cylinder uses the standard PT port thread.
To ensure a correct replacement, match five key specifications: 50 mm bore, 80 mm stroke, PT (Rc) port thread, the built-in magnet for sensor compatibility, and the Viton seal material for high-temperature operation. This model does not include a mounting accessory; separate foot, flange, or clevis mounts from the F-SC50 series can be ordered if required.
Quick checklist
At the standard operating pressure of 0.7 MPa, the cylinder provides 1374 N of force when extending. The maximum force at 0.9 MPa is 1767 N. The theoretical force at 1.0 MPa is 200 kgf. The pull force on the retract stroke is lower due to the 20 mm rod diameter, providing 825 N at 0.5 MPa.
It is a direct dimensional match for any AirTAC SC50 tie-rod cylinder with an 80 mm stroke and PT ports. The -S magnet option adds sensor compatibility without changing the external envelope. The -H Viton seal option is critical if your application runs above 70°C; a standard TPU seal cylinder would not survive in that environment.
