Abstract

PURPOSE: To improve enclosure performance as a seal incorporative form to enclose hermetically between cylindrical parts through an elastic seal material fixed on the external side by providing special cylindrical parts stretching in the axial direction to the extremity on the side opposite to the spacer between a n inner ring with double raceway and an outer ring with single raceway.
