Roller bearing for use in underwater applications, particularly in lubricated environment, has two bearing races radially stacked around rotation axis, where one of bearing races is made of radial thickness in proportional manner

摘要

The roller bearing (1) has two bearing races (3,4) radially stacked around a rotation axis (5). One of the bearing races is made of a radial thickness in a proportional manner between an outer and inner periphery, where a raceway (11,12) of certain width (b) is formed along the rotational axis. A rolling element (10) is provided, which is made of a sintered carbide hard metal or ceramic material, where a rolling element cage (13) is made of plastic.
