    摘要: A process for manufacturing a hollow roller of a roller bearing including steps of: machining an outer radial cylindrical surface, with a circular cross section centered on a first axis, and machining an inner radial cylindrical surface with a circular cross section centered on a second axis. These two steps are realized on the same lathe. The hollow roller is provided with the outer radial cylindrical surface, with a diameter of at least 5 mm, and the inner radial cylindrical surface. An offset between the first axis and the second axis, measured in the hollow roller between two axial surfaces of the hollow roller, is less than 2 μm, and an inclination angle between the first axis and the second axis is less than one minute of angle. The roller bearing comprises amongst others, at least one such hollow roller.

    摘要: A keyless coupling assembly for connecting concentric shafting components in a sealless pump comprises a first shafting member, a second shafting member and a plurality of torque strips. The first shafting member comprises an annular body and an inner surface disposed within the annular body. The second shafting member comprises a cylindrical body and an outer surface. The cylindrical body is disposed within the inner surface of the first shafting member. The outer surface encircles the cylindrical body and faces the inner surface. The plurality of torque strips is positioned between the outer surface and the inner surface to form anti-rotation grooves to prevent relative rotation between the first and second shafting members.

    摘要: [Object] To prolong the life of a shell type needle roller bearing used e.g. for a support structure for a compressor spindle or for a support structure for a piston pump driving portion, and to lower the acoustic level during use. [Means for solution] A shell type outer ring 2 of a shell type needle roller bearing 1 is formed by a pressing combined with an ironing step, and the lubricating conditions in this ironing step on the outer-diameter ironed surface, which becomes the outer-diameter surface of the outer ring 2, are in a substantially fluid lubricating state so as to restrict the circumferential surface roughness of the inner-diameter surface, the inner-diameter roundness, and the amount of uneven thickness of the tubular portion to predetermined value ranges, thereby prolonging the life of the shell type needle roller bearing and lowering the acoustic level during use.

    摘要: Manufactured by quench hardening, a bearing washer for a thrust bearing inexpensive and excellent in durability is used without being subjected to grinding after quenching. In a bearing washer group including a plurality of bearing washers for the thrust bearing, when camber/waviness of each bearing washer constituting the bearing washer group that is randomly extracted is measured, a value obtained by adding a value three times as large as standard deviation of camber/waviness to an average value thereof is at most 40 μm.
