Double Row Bearings

Double Row bearings is 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. Interchangeability is designed for the ring without the rollers to allow interchange with competitor inner rings.

Double Row bearings are ideally suited to applications where carrying loads make a single row inadequate. Double Row bearings utilize two rows of balls back to back. They have deep groove raceways with a high degree of contact between the ball and raceways. Double Row bearings are capable of handling both radial and axial loads and are designed for applications where higher load carrying capacity is necessary. The Boca Bearing Company offers a full line of miniature standard and ceramic hybrid, doubel row bearings.
