Abstract

PURPOSE: To lengthen the service life of bearing and to improve the reliability, by shifting the supporting position of housing from central position in axial direction of multi-row roller bearing for supporting the rotary shaft.
CONSTITUTION: When applied on a supporter for roll neck bearing of rolling mill, the adjustable center type supporting member 7 supported on the lower face of housing 6 in perpendicular with the axis A1-A1 is made to be a board having curved face at the side facing with the receiving seat 8, where the top 71 is shifted by distance S to axial end from axial center A3-A3 of bearing 2. Since the supporting position of bearing 2 is shifted axially from central position of bearing 2 while considering the flexure of rolling mill 1 during usage, the load can be distributed uniformly on each row of rollers 21W23 of bearing 2.
