This double row angular contact ball bearing carries the design contact angle of the X-life generation, combining two rows of balls in a single unit with a bore of 20.0 mm, outside diameter of 47.0 mm, and width of 20.6 mm. It weighs 0.151 kg and is fitted with a plastic cage (TVH) together with shields (2Z) protecting the rolling elements on both sides. The limiting speed reaches 12100 1/min, with a reference speed of 14700 1/min. The double row arrangement allows the bearing to take up combined radial and axial loads acting in both directions, which is a direct result of the angular contact design. The shields reduce the ingress of contaminants while retaining grease inside the bearing, limiting the need for frequent relubrication. The plastic cage lowers friction and mass compared to a metal cage, supporting the stated limiting and reference speed values, and contributes to smoother operation of the two ball rows working together.
