This angular contact ball bearing carries combined radial and axial loads in a single row design, transmitting force along a defined contact angle within the X-life design range. Bore diameter is 70.0 mm, outside diameter 125.0 mm, width 24.0 mm, and net mass 1.215 kg. The limiting speed reaches 9400.0 1/min, with a reference speed of 5500.0 1/min. The bearing uses a solid brass cage, designation MP. The single-row arrangement allows the bearing to take up axial load in one direction only, so it is typically paired with a second bearing for both-direction axial support. The solid brass cage (MP) provides stable ball guidance and dimensional stability at the stated speed range, supporting reliable operation under the given limiting and reference speed values. The X-life design corresponds to a tighter internal geometry tolerance, contributing to the load and speed capacity noted above.
