This single row angular contact ball bearing carries a solid brass cage (MP) and is built with a bore diameter of 320.0 mm, outside diameter of 400.0 mm, and width of 38.0 mm, giving a net mass of 10.585 kg. The limiting speed is rated at 2310.0 1/min, with a reference speed of 1340.0 1/min, and the design corresponds to the P5 accuracy class combined with the UL designation. The solid brass cage supports stable ball guidance at the stated speed ratings and contributes to consistent running behavior under axial and combined loading typical of angular contact geometry. The P5 accuracy class indicates tighter dimensional and running tolerances than standard class bearings, making this bearing suitable for applications requiring precise shaft positioning and reduced runout. As a single row design, it accommodates combined radial and axial loads in one direction, and proper mounting orientation should be maintained to preserve the contact angle characteristics of the 718.. series.
