Abstract
A cross roller bearing includes an inner ring, an outer ring and a plurality of generally cylindrically shaped rollers placed in a channel defined between the inner and outer rings as being alternately crossed with any two adjacent rollers having their axes of rotation directed perpendicular to each other. Both of the inner and outer rings are unitary in structure. In one form of the invention, the outer ring is provided with a radial hole extending therethrough radially, through which the rollers may be inserted in the channel defined between the inner and outer rings. An insert is also provided to be fixedly fitted into the radial hole so as to close the radial hole after insertion of the rollers into the channel.
