Mounting hub/bore is a precision component in cam mechanisms that provides secure attachment and rotational interface between camshafts and driven elements.
A mounting hub/bore is a cylindrical mechanical interface component designed to connect rotating cam elements to shafts or other driven components in cam mechanisms. It features precise internal bore dimensions for shaft fitting and external hub geometry for cam attachment, ensuring accurate torque transmission and rotational alignment while maintaining structural integrity under cyclic loading conditions.

The mounting hub/bore serves as the critical interface that securely connects cam elements to rotating shafts, ensuring precise torque transmission, accurate angular positioning, and synchronized motion between cam and driven components while maintaining structural integrity under operational loads.
Mounting hubs/bores are secured using interference fits (press fits), keyways with keys, splined connections, or clamping mechanisms. The selection depends on torque requirements, disassembly frequency, and precision needs, with interference fits providing the highest concentricity for precision applications.
