Wear-proof insert larger base is located in the sleeve on flange side. Note here that sleeve diameter at section from wear-proof-insert larger base to flange is smaller than that of wear-proof insert larger base. Sleeve at wear-proof insert section location has conical outer surface with imaginary vertex located on the wear-proof insert smaller base side.
