This is a single row angular contact ball bearing designed to carry combined radial and axial loads in one direction, with a bore diameter of 85.0 mm, outside diameter of 150.0 mm, and width of 28.0 mm. The bearing weighs 1.806 kg and belongs to the X-life design line, offering a limiting speed of 5900 1/min and a reference speed of 4750 1/min. It is fitted with a TVP cage made of glass-fibre reinforced plastic, which reduces friction and mass compared to solid cage designs. The contact angle of this bearing type allows it to accommodate axial loads acting in a single direction combined with radial loads, making paired mounting suitable where bidirectional axial support is required. The plastic cage design supports smooth ball guidance at the stated speed ratings, while the X-life manufacturing standard indicates tighter internal geometry tolerances contributing to consistent running accuracy. The bearing is supplied without integrated sealing, so lubrication and contamination protection must be provided by the housing arrangement.
