What Through-Bore Diameter Do I Need for a Slip Ring?

The required through-bore diameter depends mainly on the shaft, cable, air line, or other components that need to pass through the center of the slip ring. When selecting a through-bore slip ring, first confirm the actual diameter of the component passing through the bore and the available installation space.

You should also consider the assembly method and whether additional clearance is required for installation and maintenance. The required bore size should therefore be determined from the actual mechanical structure rather than selected only by the slip ring model name.

For applications with special dimensional requirements, a customized slip ring can be evaluated based on the equipment drawings or installation dimensions.
