    摘要： Provided are that a cage for a rolling bearing in which seizure or break is not generated under a condition of a high temperature and a high speed in which a dm·n value is not less than 80×104, and a rolling bearing using the cage. The rolling bearing 1 is provided with an inner ring 2, an outer ring 3, a plurality of rolling elements 4 interposed between the inner ring and the outer ring and a cage 5 which retains the rolling elements 4. The cage 5 is formed by injection molding a resin composition. The resin composition comprises polyamide resin made from a dicarboxylic acid component and a diamine component as a base resin and a fiber reinforcing member added. The dicarboxylic acid component contains terephthalic acid as a main component. The diamine component contains 1,10-diaminodecane as a main component. The fiber reinforcing member contains 15 to 50 mass % of glass fibers or 10 to 35 mass % of carbon fibers based on the whole resin composition.

    摘要： A bearing member includes a concave section receiving a spherical body therein, and swing grooves into which end sections of a rotating force transmission pin are inserted. The swing groove at least includes a parallel part an axis and a curved part, an undercut section is not provided in the concave section when the concave section is viewed from an opened side of the concave section in a direction of the axis of the bearing member, and a clearance between the two swing grooves in a direction which is orthogonal to the direction of the axis on the opened side of the concave section is shorter than a distance between both ends of the rotating force transmission pin in the direction which is orthogonal to the axis of the bearing member even when the shaft member is mounted on the bearing member in a posture inclined at the most.

    摘要： For the manufacture of a heavy duty elastomeric having a stack of elastomeric and metal reinforcing layers interleaved with one another use is made of a mould sufficiently large to allow an elastomeric cover layer to be formed and cured simultaneous with compression and cure of the elastomeric layers. Relative transverse movement of the metal layers during compression is restricted by spacers which occupy in the mould a small part of the space that in the finished product is to be occupied by the cover layer. Subsequent to moulding and cure the spacers are removed and the resulting spaces in the part formed cover are filled.

    摘要： The resin injection gate is disposed at the pillar part. When the bearing cage is divided into first and second regions by an imaginary line connecting the resin injection gate and a weld to be formed at a position radially facing the resin injection gate, a resin reservoir that can store therein the melted resin is formed at the pillar part in only one of the regions. A circumferential distance between the resin reservoir and the weld is smaller than a circumferential distance between the resin reservoir and the resin injection gate. A cross-sectional area of a communicating part of the resin reservoir, which is configured to communicate with the pillar part, is equal to or less than a quarter of a cross-sectional area of the resin injection gate.
