Abstract

A composite bearing is provided comprising: (i) a continuous annular element (15) made from a silicon-carbide-cemented diamond (SCD) composite material or from silicon carbide; and (ii) an element (24) comprising another superhard material optionally diamond material which has been deposited or grown onto the silicon- carbide-cemented diamond (SCD) or silicon carbide element (15). The other superhard element (24) covers at least part of a surface of the SCD or SiC annular element (15) and provides at least part of the wear surface of the composite bearing.
