Abstract
A roller and cage assembly is able to accept large loads due to the high rigidity of the cage, while having an excellent lubrication property that enables it to demonstrate favorable high-speed rotation performance even under conditions of low levels of lubrication, thus giving it a high level of universal applicability. The rigidity of the cage is increased by providing thick-walled portions on each column of the cage. Together with being formed on a straight line, these thick-walled portions provide reinforcing action at prescribed locations. In addition, these thick-walled portions also function as guide portions that guide the rollers. These thick-walled portions are arranged so as to correspond to the center slit formed in the big end of a connecting rod for supplying lubricant, thereby enabling them to achieve improved lubrication performance.
