The 72/710-B-MPB Single-row angular contact ball bearings mainly consist of an inner ring, an outer ring, steel balls, and a cage. The raceways of the inner and outer rings are offset from each other, forming a contact angle. They are typically designed as non-separable bearings with contact angles of 15°, 25°, or 40°. The cage can be made of solid brass or phenolic resin.

The larger the contact angle of a single-row angular contact ball bearing (e.g., 40°), the stronger its axial load capacity. 15° or 25° contact angles are suitable for high-speed applications. They can simultaneously withstand radial loads and unidirectional axial loads. When installed in pairs (back-to-back, face-to-face, or in series), they can withstand bidirectional axial loads and improve rigidity. Larger bearings have higher basic dynamic load ratings, reaching hundreds of kN or more.
