特徴とする円すいころ軸受。 In a tapered roller bearing in which a collar is formed on the large diameter side of the inner ring, a protrusion facing the large end surface of the roller is formed on the large diameter side of the outer ring provided on the outside of the inner ring,
The initial axial clearance between the large end faces of the protrusion is made smaller than the axial clearance during operation caused by the difference in linear expansion coefficient between the shaft supported by the inner ring and the housing supported by the outer ring. A tapered roller bearing characterized by:
