Document Type and Number:
Japanese Patent JP2006349081
Kind Code:
A
Abstract:
To provide a structure which achieves control of wear and heat generation produced in a butt part 15 between inside surfaces of rim parts 7a in retainers 4a, 4a.
An oil guide groove 16 is formed in a radially outer end of the butt part 15. By so doing, lubricating oil supplied through an oil penetrating hole formed in a width-wise intermediate part of an outer ring or grease existing between the outer ring and the retainers 4a, 4a is retained in the oil guide groove 16 so as to be effectively fed in the butt part 15. As a result, wear and heat generation produced in the butt part 15 can be controlled.
