摘要： A cage segment for a bearing rotatable around an axis of symmetry that defines an axial direction and able to receive a plurality of rolling elements and having an inner and outer walls that extend circumferentially in the form of a of cylinder. A plurality of radial beams extend globally radially with respect to the axis and connecting the inner and outer walls. Each axial radial beam having a central portion and two end portions that are opposite with respect to the central portion. The central portion being symmetrical with respect to a plane of symmetry. The plane of symmetry of the at least one end portion cooperating with a rolling element to center the segment, forms with the plane of symmetry of the central portion an angle which is not equal to zero.

摘要： In a finite linear motion guide unit, a retainer for retaining rollers rolling between guide members is formed into a V-like shape to thereby increase a rated load. A first guide member is formed into a V-like concave form, and a second guide member is formed into a V-like convex form. Needle rollers are retained by the V-shaped retainer and roll on a raceway formed by facing surfaces of the guide members. The V-shaped retainer includes a pair of roller retainer plate portions for retaining the needle rollers, and a retainer connection portion. A retainer straying prevention mechanism is composed of a pinion disposed in a cross-opening, and racks disposed on the guide members and meshing with the pinion.

摘要： A method of splitting a ring, such as a cage, for a bearing, such as a roller or ball bearing, includes splitting a ring in such a way that there are provided projections and recesses in the facing surfaces thereby produced. In this manner, the two halves of the split ring may be reassembled in opposite orientation so that the projections on the facing surfaces of the two halves of the ring engage one another to space the two halves of the ring apart and to restore the ring to a circular ring shape despite some of the material of the ring having been removed in the splitting process.

摘要： The invention relates to a method for producing a rolling bearing cage for a rolling bearing comprising at least one row of rolling elements. In the method according to the invention, a ring or a ring element made of a metallic solid material is provided and shaped by a forming process and/or a cutting, material-removing process into an annular or segmented main body of the rolling bearing cage. The main body has openings for receiving a respective rolling element, the main body being heated to a temperature above a minimum coating temperature for thermal coating with a thermoplastic material powder, wherein the main body is then immersed in a fluidized bed containing the thermoplastic material powder, wherein thermoplastic material powder adheres to the main body, melts and forms a contiguous coating while the main body is present in the fluidized bed, and wherein, after the coating, the main body is removed from the fluidized bed. The invention further relates to an axial-radial rolling bearing with the described rolling bearing cage.
