BALL RACE SUPPORT MANUFACTURING METHOD Russian patent published in 1995 - IPC

Abstract RU 2041269 C1

FIELD: metallurgy. SUBSTANCE: method involves manufacturing billets from medium-alloy constructional steel; hardening from heating temperature of 860-900 C; tempering at 550-600 C; providing surface-plastic deformation of race by means of working bodies of revolution of support and ionic nitridation. EFFECT: increased efficiency in manufacture of thin-walled rings of bearings. 1 tbl
