Roller bearing for traction mechanism drive of motor vehicle, has encompass wall forming support surface in zone through which spherical center path region is passed, where support surface is limited by lubricant passage channels

摘要

The roller bearing has a roller body held in a roller body path space between an inner ring and an outer ring. A cage device (1) is made of plastic material and provided with an inner wall (I) turned towards the inner ring and an outer wall (A) turned towards the outer ring. Window openings (F1-F3) in a circumferential direction for positioning the roller body within the path space. An encompass wall forms a support surface (4) in a zone through which a spherical center path region (PZA) is passed. The support surface is limited by left and right lubricant passage channels (2, 3).
