Double row 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. 


These two row bearings are designed in a way that allows them to accommodate thrust in two directions.  They are supplied in two designs in order to maintain a non-separable unit. Design 1 has a single double-row inner race, while design 2 has a single double-row outer race. Due to their construction, they are supplied with a very small positive axial clearance. Since this typical bearing has a special bearing number, no suffixes defining the cage type, contact angle or axial clearance are shown in the bearing number. ISO standard metric sizes are available in 190mm to 280mm bore range. These bearings are frequently found in rolling mills as roll thrust bearings.
