Abstract: A ball bearing includes an inner ring; an outer ring placed outside of the inner ring; a plurality of rolling bodies intervening between the inner ring and the outer ring; and an annular cage including pockets rotatably holding the rolling bodies in a circumferential direction at intervals determining a rotation axis to be a center. The cage comprises a resin composition comprising a polyetherketone-based resin, graphite, and a carbon fiber. The resin composition comprises the polyetherketone-based resin in an amount of 60% by weight or more and 80% by weight or less, the graphite in an amount of 10% by weight or more and 30% by weight or less, and the carbon fiber in an amount of 5% by weight or more and 20% by weight or less when the entire resin composition is determined to be 100% by weight.

Abstract: A bearing unit comprising rolling elements, housed in a radially inner mounting seat of a casing. The bearing unit includes a radially outer and stationary coated ring provided with a metal ring and a liner of elastomeric material integral with a radially outer surface of the metal ring, a radially inner ring, which is rotatable with respect to an axis of rotation (X), and a row of rolling elements interposed between the coated ring and the radially inner ring. The elastomeric material of the liner is a vulcanized thermoplastic material. The liner is co-molded onto the radially outer surface of the metal ring and may include a cylindrical body and at least two annular protuberances which fit inside corresponding anchoring grooves formed on the surface of the metal ring.

Abstract: To provide an insulating rolling bearing that is capable of preventing electrolytic corrosion and preventing a gap from being undesirably formed between a shaft and a raceway ring. A sub bearing 21 includes an inner ring 22, an outer ring 23, balls 24 interposed between the inner ring and the outer ring, and an insulating bushing 28 fitted to an inner peripheral portion of the inner ring 22. The insulating bushing 28 includes a generally cylindrical metal base 28a, and a resin layer 28b formed on an inner peripheral surface of the metal base 28a. The insulating bushing 28 is fitted to the inner peripheral portion of the inner ring 22 such that the metal base 28a abuts on the inner peripheral portion of the inner ring 22.

Abstract: A rolling bearing including an outer ring, an inner ring, rolling elements interposed between the outer ring and the inner ring and a cage for retaining the rolling elements and provided with radial seats or pockets for housing the rolling elements. The cage is guided supportingly on the outer ring with which a first clearance (G1) is defined, while between the pockets and the rolling elements there is a second clearance (G2) such that they have a relative ratio of between about 0.4 and 1. The rolling elements may be balls and the pockets may be formed by radial through-holes, which are circular or square in shape.
