The AirTAC SC50 Standard Cylinder SC50X70H is a genuine double-acting standard air cylinder with a Ø50mm bore and 70mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC50X70H is a double-acting pneumatic cylinder equipped with high-temperature Viton (FKM) seals, extending the operating range from 0 to +150 °C for demanding hot environments. With a 50 mm bore and 70 mm stroke, it delivers a push force of 982 N at 0.5 MPa and 1767 N at the maximum operating pressure of 0.9 MPa.
This model features a 20 mm diameter piston rod with M16x1.5 male threads and PT1/4 ports. The adjustable air cushion at each end is 21 mm long, providing smooth deceleration. Its body length A is 150 mm, resulting in a compact extended length of approximately 220 mm for this stroke.

Operates reliably near furnaces and ovens where ambient temperatures exceed 70°C, using Viton seals to maintain consistent 982 N push force at 0.5 MPa.
Withstands repeated steam sterilization cycles in medical and food processing equipment, thanks to the 0-150°C temperature rating of the FKM seal material.
Provides 1767 N of clamping force at 0.9 MPa for heated platen presses, where the 20 mm rod and 21 mm cushion ensure stable, shock-free mold closure.
Select the SC50X70H when your application requires reliable actuation in elevated temperatures where standard seals would degrade. If you need more force, stepping up to the 63 mm bore provides 1559 N of push at 0.5 MPa. For a lower force requirement, the 40 mm bore offers 628 N. When replacing an existing cylinder, ensure a 5-point match: 50 mm bore, 70 mm stroke, PT1/4 port thread, basic mounting (no bracket), and no magnet. The Viton seal variant is specifically for high-temperature compatibility.
Quick checklist
At 0.5 MPa, the push force is 982 N and the pull force is 825 N. At 0.7 MPa, push force increases to 1374 N. The maximum operating pressure of 0.9 MPa yields 1767 N of push force.
Yes, the Viton seals work perfectly from 0°C upwards, but they are specified primarily for high-temperature environments up to 150°C. For standard -20 to +70°C applications, the TPU seal version (SC50X70) is a more cost-effective choice.
