ABSTRACT:
Firstly, a roller and cage assembly is disclosed that achieves improved lubricating property while maintaining or increasing rigidity. While concave portions are formed so as to extend the width of the central portion of pockets to allow these to act as oil grooves, on the other hand, padding equivalent to lightening holes that are removed by providing said concave portions is performed in columns to obtain high rigidity.
Secondly, a roller and cage assembly is disclosed that together with being inexpensive and having high wear resistance, suppresses the generation of heat resulting from high-speed rotation. The above-mentioned effects are obtained by forming a composite plated film at prescribed sites by uniform dispersed coprecipitation of fine particles of fluororesin.
Thirdly, a roller and cage assembly is disclosed that together with suppressing the generation of heat resulting from high-speed rotation, also achieves light weight. The above-mentioned effects are obtained by using ceramic rollers.
