Sizing

The number and diameter of holes together with the PCD determines the backing ring size and pattern.  The PCD (Pitch Circle Diameter) is the measurement from the centre of one bolt hole, across the centre of the backing ring, to the centre of the opposite hole.

The table below details the specification for both imperial and metric PN10/16.  We can also supply Table D/E if required.
