Abstract
The present invention relates to a sliding bearing with improved wear resistance which is manufactured in a sintered body type, and more particularly, to a bush type of sliding bearing that has excellent friction and wear characteristics with a shaft usually made of an iron-based material even under very poor sliding conditions of high-surface pressure, low speed, and irregularity, such that the lubrication cycle of may be extended, and also has excellent hardness such that load feed capability, plastic deformation suppression, and fatigue strength can be improved.
