Timken® Double Row Cylindrical Roller Bearings
Timken® Cylindrical Roller Bearings
Timken two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. Double row full complement cylindrical roller bearings are also available to meet the need for radial load carrying capacity.
