Abstract
The present invention provides a member for a rolling bearing () which is capable of decreasing the amount of carbon dioxide generated from a polymeric member in discarding the rolling bearing, contributing to restraint or prevention of an increase in the concentration of the carbon dioxide in the atmosphere or a decrease of the concentration thereof in the atmosphere, and allows a continuous use temperature to be high and an endurance time to be long and a rolling bearing using the member. The member for the rolling bearing () is composed of a molding of a polymeric elastic body or a synthetic resin composition. The member is at least one member selected from among an inner ring (), an outer ring (), rolling elements (), a retainer (), and a sealing member (). A raw material derived from a biomass is at least partially used for a producing raw material of a polymeric matrix composing the polymeric elastic body or the synthetic resin composition.
