CYLINDRICAL ROLLER BEARING AND TRANSMISSION BEARING DEVICE

摘要

A cylindrical roller bearing includes an outer ring having, on an inner circumferential surface, an outer ring raceway and a pair of outer ring ribs which are provided on both sides of the outer ring raceway in an axial direction, an inner ring having, on an outer circumferential surface, an inner ring raceway and an inner ring rib which is provided on one side of the inner ring raceway in the axial direction, and a plurality of cylindrical rollers disposed between the outer ring raceway and the inner ring raceway. A radial height of the outer ring rib is greater than a radial height of the inner ring rib, and a radial clearance between the outer ring rib and the inner ring rib is set to be equal to or less than 2 mm.
