This angular contact ball bearing is a single row design featuring the X-life optimized internal geometry and a solid plastic TVP cage. Bore diameter is 50.0 mm, outside diameter 110.0 mm, width 27.0 mm, and net mass 1.055 kg. Limiting speed is rated at 8400 1/min, with a reference speed of 6100 1/min. The single row angular contact configuration carries combined radial and axial loads acting in one direction only, so these bearings are commonly arranged in pairs where axial loads can reverse. The TVP plastic cage keeps friction and rotating mass low, supporting operation up to the stated limiting speed, while the X-life geometry provides increased load carrying capacity compared with the standard 7310-B design in the same mounting envelope.
