Transfers combined radial and axial loads in a single direction through a defined contact angle, supported by a solid brass cage (MP) that guides the ball set at higher speeds. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, net mass 1.53 kg. Limiting speed is rated at 10000 1/min, reference speed at 5600 1/min, consistent with X-life ball and raceway geometry that raises load carrying capacity within the standard envelope. Because it is a single-row angular contact ball bearing, it should be mounted in pairs or against a counterpart bearing when axial loads act in both directions, or used alone where load direction is fixed and defined. The brass cage construction supports stable ball guidance up to the stated limiting speed, making the bearing suitable for arrangements requiring precise axial positioning under combined loading. No sealing or lubrication is specified, so grease or oil supply and sealing must be provided by the housing design.
