This angular contact ball bearing transmits combined radial and axial loads through a single row of balls set at a defined contact angle, keeping the shaft and housing positioned axially in one direction. Design 7304-B-XL-TVP-UA has a bore diameter of 20.0 mm, outside diameter of 52.0 mm, and width of 15.0 mm, with a net mass of 0.145 kg. It uses a TVP plastic cage as part of the X-life design, supporting a limiting speed of 19300 1/min and a reference speed of 11500 1/min. The plastic TVP cage reduces friction and mass compared to metal cages, allowing operation closer to the limiting speed while keeping running noise and heat generation low. Because it is a single-row angular contact type, it should be mounted against a matching bearing to absorb axial forces from both directions, and axial preload should be set according to the required stiffness. The X-life optimization improves load distribution across the balls, which is relevant when working near the stated speed limits or under combined load conditions.
