    摘要: A roller bearing retainer comprising a substantially ring-shaped member having a plurality of ball pockets formed thereon to hold rolling members. Each ball pocket has a flat portion formed at its bottom portion and an opening portion extending from the flat portion of the retainer's ball pockets for receiving a rolling member. Each rolling member is held by a ball pocket having the flat portion whereby movement of the rolling member is suppressed. At the same time, a sufficient gap may be formed between the rolling member and a concave surface other than the flat portion. Thus, lubrication oil may readily be placed into the gap.

    摘要: The invention has plural plate-like members, each molded by a metal die using a synthetic resin material in a shape having pockets for retaining rolling elements. A shape obtained by mutually connecting each of the plural plate-like members with connecting portions at both ends is a substantially cylinder shape. A shape of a section between both end portions of each plate-like member has a convex warped shape constituting a part of the cylinder by being subjected to a distortion action owing to heat contraction after being molded by the metal die.

    摘要: A window-type cage for an angular contact ball bearing. Lubricant pockets are provided in the spherical pocket surfaces which are provided for guiding the balls. These lubricant pockets are all arranged in regions which lie outside the bearing points between the ball and the cage in both the circumferential direction and the axial direction, such that the wall thickness of the cage at the bearing points is not reduced by the position and design of the lubricant pockets.

    摘要: A needle roller bearing includes a plurality of needle rollers that each have first and second end portions and that are disposed circumferentially around a shaft, a cylindrical first retainer member having a plurality of first notches each respectively adapted to rotatably support the first end portion of a respective one of the rollers, and a cylindrical second retainer member located spaced apart from and opposite the first retainer member and having a plurality of second notches each respectively adapted to rotatably support the second end portion of a respective one of the rollers. A plurality of voids are provided to form grease-containing spaces between the adjacent rollers and between the first and second retainer members so that the roller bearing is sufficiently lubricated.

    摘要: An improved cage is provided for a roller bearing for use in a hub assembly, for example. The cage includes roller pockets which fully entrap the roller in the cage, to maintain the radial and axial position of the roller in the cage. Additionally, the bearing for the hub assembly is formed in part by the hub. One of the inner races is formed integrally with the hub. These constructions allow for the cage/roller assembly to be installed in the outboard position of the hub prior to the hub and hub seal being installed in the hub assembly.

    摘要: A cage for a ball bearing, having a front face with cells adapted to hold a row of balls, and a rear face including a ring-shaped body with slots. The slots are adapted to interlock with slots of a second cage. The slots have teeth that extend towards the front face and separate the cells, and the teeth have sides with semispherical bearing surfaces oriented towards a center of a respective cell. The front face includes a closing ring linking the teeth, were the closing ring is adapted to be recessed in relation to an axial extremity of the balls. Additionally, a bearing is provided that includes an outer bushing, an inner bushing, a row of balls, and a cage configured to receive the row of balls, where the cage and the row of balls are received between the outer and inner bushings.
