Angular contact ball bearing 3306-BD-XL-TVH-C3 transfers combined radial and axial loads through two rows of balls arranged in an X-life design, which increases the number of rolling elements compared to standard execution. Bore diameter is 30.0 mm, outside diameter 72.0 mm, width 30.2 mm, mass 0.538 kg. Limiting speed is 10400 1/min, reference speed 8500 1/min. The cage, marked TVH, is made of plastic, which reduces friction and mass compared to a solid cage. The C3 internal clearance is larger than standard, which compensates for tighter fits and thermal expansion during operation at elevated temperature. The double-row arrangement allows the bearing to take up axial loads from both directions without a mating bearing, while maintaining defined radial guidance of the shaft. As an open design without integrated seals, it requires external sealing and a separate lubrication supply matched to the reference speed value.
