This double row angular contact ball bearing carries radial and axial loads in both directions within a single unit, thanks to its two rows of balls arranged at a contact angle. The bore diameter is 45.0 mm, outside diameter 85.0 mm, and width 30.2 mm, with a net mass of 0.622 kg. Built to the X-life standard, it uses a TVH cage made of glass-fiber reinforced plastic, which reduces friction and allows a limiting speed of 6300 1/min and a reference speed of 8400 1/min. The bearing is fitted with shields on both sides. The C3 internal clearance accommodates thermal expansion during operation and slight shaft misalignment without loss of preload, while the shields protect the raceway and balls from external contamination, limiting the need for relubrication. The plastic cage lowers rotational mass and heat generation compared to solid cage designs, supporting stable operation at higher speeds. The double row, back-to-back type contact geometry makes this bearing suitable for applications where combined radial and bidirectional axial loads must be supported by a single, compact bearing position.
