IRON BASED SINTERED BEARING AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: A ferrous sintered bearing and a manufacturing method thereof are provided to improve abrasion resistance and anti-seizure property. CONSTITUTION: An iron based sintered bearing consists of Cu: 2.0-9.0% C: 1.5-3.7%, and remnant of Fe. An iron alloy phase is made of ferrite 20~85% and the remnant of pearlite. The copper phase is extended to the direction crossing to the axial direction of the bearing.
