ABSTRACT:
A rolling contact type rotary bearing assembly includes a pair of inner and outer rings and a plurality of rolling members interposed therebetween to provide a relative rotation between the inner and outer rings. An insertion hole is provided in at least one of the inner and outer rings such that the plurality of rolling members may be inserted into the annular path defined between the inner and outer rings. A closure member is also provided to close the insertion hole after insertion of the rolling members into the annular path. The closure member is formed with a lubrication hole so that a lubricant may be provided to the annular path to allow a smooth rolling movement of the rolling members. A lubricant supply hole may also be provided in either of the outer and inner rings in communication with the lubrication hole of the closure member so as to allow to supply a lubricant to the annular path from the exterior.
