摘要： In a rolling bearing including an inner race; an outer race; a plurality of rolling elements rollingly arranged between the inner race and the outer race; and a cage holding the rolling elements, the cage has an annular shape and a plurality of pockets which are formed at plural positions in a circumferential direction of the cage, in which each of the pockets has an opening peripheral portion which is curved to a direction of increasing a distance from a center of the rolling elements. The opening peripheral portion forms a chamfered face or a convex face. The rolling bearing can sufficiently ensure the lubrication of sliding contact portions between the cage and rolling elements so that vibrations and noises of the rolling bearing are lowered.

摘要： A pulley support double row ball bearing is disclosed, which improves the seal performance of the seal rings and is able to maintain sufficient durability even under severe conditions. The ball bearing includes inner sections of the seal rings which overlap the end surfaces in an axial direction of the inner ring such that the width of the overlap in the axial direction is 30% or more than the diameter of the balls. Moreover, tip edges of first and second protrusions are formed on the inside surface of the seal lips and come in sliding contact with end surfaces of the inner ring. Furthermore, third protrusions come close to and face the corner sections of the inner ring to form labyrinth seals in those areas.

摘要： In a seal-type rolling bearing, between an inner ring and an outer ring, contact-type seal plates are respectively interposed on the counter-water-drenchable side and on the water-drenchable side. On the counter-water-drenchable side, a seal plate including, in the lip leading end portion thereof, an air hole for controlling the internal and external pressures of the bearing is disposed. On the water-drenchable side, a seal plate without air hole is disposed.
