The SCT cylinder is an AirTAC-standard, double-acting, multi-position cylinder (also commonly referred to as the SUT dual-stroke or booster cylinder).
It consists of two SC standard cylinders connected in series, enabling a two-stage stroke and multiple positioning points.

Cylinder Theoretical Output Table (Unit: N)
The force output chart for pneumatic cylinders constitutes one of the critical elements in the cylinder selection process, enabling the calculation of the required load force.
Multiplying the output force of a pneumatic cylinder by a factor of 0.5 to 0.7 yields the cylinder’s effective load force.
