This angular contact ball bearing carries combined radial and axial loads in one direction, using a single row of balls set at a contact angle to transmit axial forces alongside radial loads. Bore diameter is 45.0 mm, outside diameter 85.0 mm, and width 19.0 mm, with a net mass of 0.405 kg. The cage is a plastic X-life design (TVP), which reduces friction and mass compared to a solid cage. Limiting speed is rated at 11000 1/min, with a reference speed of 8000 1/min. The single-row angular contact design means this bearing is typically mounted in pairs or sets to support axial loads from both directions, with the contact angle allowing for stiff, precise shaft positioning. The X-life plastic cage contributes to smooth running at higher speeds and stable guidance of the balls, supporting the rated limiting and reference speed values. As supplied open (no seals or shields indicated), lubrication and contamination protection must be provided externally, and mounting should account for the directional axial load capacity inherent to this bearing type.
