Abstract
A small bearing which has the characteristics of a sliding bearing having a small coefficient of friction and of a rolling bearing, includes an outer metallic cylinder, a plastic inner cylinder, rolling elements, and a collar, with a plurality of rolling element holding grooves being provided on the outer peripheral surface of the inner cylinder. The grooves are formed in parallel with the axis of the bearing, and the rolling elements positioned therein are rotatable. Grease can be applied to the outer peripheral sur#ace of the inner cylinder, which holds the rolling elements, and the entire inner cylinder is covered with the outer cylinder, with the end portions of the outer cylinder being bent toward the axis. By forming the metal components from an austenite-type stainless steel, the problem of corrosion may be overcome.
