Rolling body i.e. ball, for roller bearing, has cavity and two openings that lie opposite to each other, where body is in form of ball whose surface is flattened in region of openings

摘要

The body (1) has a cavity and two openings that lie opposite to each other, where the body is in the form of a ball whose surface is flattened in a region of openings (2). The radius in the region of the opening is lesser than the radius of a vertical. Flattened sections of a surface of the body and a spherical section of the surface of the body pass into one another continuously. The body is manufactured by pressing under pressure, hot transforming under rotation, forging, pouring, sintering, extrusion molding, interior high pressure transforming, sheet-metal forming or by cutting. An independent claim is also included for a roller bearing comprising an outer ring.
