    摘要: In an assembly of linear feeding means in which a carrying or carriage member is supported on a rod shaped supporting member and these two members can be relatively moved in lengthwise direction, a plurality of recesses each having a shape or arrow head are disposed such that the tip end of each of the arrow head type recesses is directed to either one direction or to the other opposite direction of the relative movement of the assembly.By virtue of this construction, hydrodynamic pressures are directed in both directions as to ensure smooth running of the assembly.

    摘要: A bearing with dynamic pressure grooves includes an outer cylinder made of a metal and a resin sheet bonded to the inner peripheral surface of the outer cylinder. The resin sheet is made of a thermoplastic resin, for example, a polytetra fluoroethylene, as a main component mixed with a wear-resistant improving material, for example, graphite or the like. The resin sheet is formed with a pattern of dynamic pressure generating grooves formed in an inner surface by plastic work. The pattern of grooves is varied depending on the types of relative movement between the outer cylinder and a shaft body, i.e., whether an axial linear movement, a rotational movement, or a spiral movement.

    摘要: A rolling bearing with the sealing device which has a fitting groove and sealing device with a mounting portion. The fitting groove formed on the inner peripheral surface of an outer ring. An outside surface of the fitting groove tilts at 5 to 30 degrees with respect to an radial direction of the bearing. An inside surface of the fitting groove tilts at a tilt angle smaller than that of the outside surface. A total of these tilt angles is 35 degrees or more. The mounting portion has a base portion contacting the inside surface and a portion projecting toward the outside surface of the fitting groove from the base portion, and the mounting portion is thinnest at a front end portion of the projecting portion.

    摘要: A rolling bearing comprising an outer race having one track, an inner race having the other track, a plurality of rolling elements arranged between the both tracks, and a cage for retaining the plurality of rolling elements in such a way that the rolling elements can roll freely, wherein the cage is a lubricating oil-containing polymer member obtained by molding a synthetic resin containing 10 to 80% by weight of a lubricating oil. The cage retains a sufficient amount of a lubricating oil at a high rate of retention so that a lubricating action can be maintained in a stable manner for a prolonged period of time, and it is produced at low cost.

    摘要: A distal edge of an outside seal lip 22a is brought into sliding contact with an entire circumference of the surface of a mating member. A contact angle β that is formed at a sliding contact portion between the distal edge of the outside seal lip 22a and the mating member on the side of an interior space 33 is made to fall within a range of 13 to 45 degrees by providing a bent portion 34 at a portion on the outside seal lip 22a which lies closer to a distal end thereof.
