Abstract
A cross roller bearing is disclosed that achieves a long service life by reducing the effects of split surfaces formed in an outer ring in the direction that crosses a V-shaped groove of said outer ring. In addition, a cross roller bearing is disclosed that allows said effects to be reduced at low cost. The above-mentioned advantages are obtained by forming a recess in the outer surface of said outer ring corresponding to said split surfaces to reduce the preliminary pressure applied to rollers at that portion. In addition, the above-mentioned advantages are achieved at low cost by the filling of a filling member and the setting of the angle at which said split surfaces cross said V-shaped groove.
