Cylindrical Roller Back Bearings
Cylindrical roller bearings are backing two or three rollers , have full roller bearings ( without cage ) or with cage bearing forms , with or without integral flanges or retainer . Advantages no bearing wall that they particularly simple geometric shapes and very high radial load capacity . No ribs or collar of cylindrical roller bearings can not afford any backing axial load. Therefore it is necessary to place the bronze or plastic saddle between the outer ring and the support side surface of the thrust washer . Backing with a wall ( or retainer ) bearing thrust washers do not need , because these bearings are designed so that they can support radial and axial forces acting . Cylindrical roller bearings are the most commonly used backing bearings.
