Double Row Bearings

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.The raceways in these bearings are positioned off-center to handle angular (combined radial and thrust) loads. Double-row bearings handle thrust loads in both directions. Open bearings dissipate heat more efficiently than shielded and sealed bearings.

 

Double Row Angular Contact Ball Bearings have two seprate rows of balls arranged back-to-back. The lines of action of the load at the contact between balls and raceways (load lines) diverge at the bearing axis and form an angle of 30° to the radial plane.
