    摘要： A rolling bearing for a rotary shaft of a disk memory device which can maintain high-accuracy optical or magnetic recording ability over a long period of time. The rolling bearing supports a rotary shaft of a disk of disk memory device or a rotary shaft of an arm of a head, and has an inner ring having an inner diameter of 8 mm or less, and a retainer formed by molding an oil-containing resin composition comprising 40-94 wt % of a synthetic resin, 1-40 wt % of oil conducting material, and 5-30 wt % lubricating oil. Lubricating oil is dispersed uniformly in the composition, and can bleed onto the surface through the fibrous oil conducting material.

    摘要： A cam follower includes a shaft member which is cantilevered at one end and a slide bearing fitted onto the outer periphery of the other end of the shaft member. The slide bearing is composed of a cylindrical matrix made of an Fe-based sintered metal material having an Fe content of 90 wt % or more and a slide layer formed from the inner peripheral surface to the both end faces of the matrix. The slide layer is made of a slide material composition having a base material such as polyethylene resin blended with a lubricant such as silicone oil and a globular porous silica impregnated with this lubricant.

    摘要： A polyether imide resin composition is proposed which has improved ductility and is less harmful to mating parts during sliding and thus can be used as the material for parts requiring rub resistance and abrasion resistance. It comprises 50-99.5 percent by weight of a polyether imide and 50-0.5 percent by weight of a vulcanizable organopolysiloxane elastomer.
