Double inner double row bearings are ideally suited to applications where carrying loads make a single row inadequate.Double inner 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 inner double row bearings are capable of handling both radial Double inner double row bearings inch 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. 

Double inner double row bearings uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions. They have higher load carrying capacities and higher stiffness. Furthermore, the raceways NSK 6005 Bearing and rollers on the two rows are tapered in opposite direction so they can carry axial loads in both the directions. are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate. For the same bore and outside diameter, double row bearings have a considerably higher load carrying capacity.
