ABSTRACT:
A ring comprising separable segments especially for seating against a rotary seal and a method of manufacturing such a ring which comprises forming and assembling the segments into the ring, clamping the ring segments together, e.g. by bolts, forming at least one tapered passageway in the ring across each joint between mating segments and inserting a tapered pin into the tapered passageway to hold the segments against relative sliding movement before a finishing operation is performed on an end face or the bore of the ring so that such end face or bore can act as an effective rotary seal.
