Radial roller bearing i.e. single-row cylindrical roller bearing, has axially spaced guide rims with annular contact areas forming free spaces in which no contact with front surfaces of rolling members is achieved

摘要

The bearing (1) has rolling members (4) arranged between outer and coaxial inner bearing rings (2, 3) and rolling on raceways (5, 6) at the bearing rings. Axially spaced guide rims (8, 10) at the bearing rings radially extend over pitch circle diameter (26) of the bearing. Front surfaces (15, 16) of the rolling members are formed in convex shape, and annular contact areas (11, 12) of the guide rims are concavely curved. The annular contact areas form free spaces (17, 18) in a narrow region of the pitch circle diameter, where no contact with the front surfaces is achieved in the free spaces.
