Angular Contact Ball Bearings
Since these bearings have a contact angle, they can sustain significant axial loads in one direction, together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced, therefore, two opposed bearings or a combination of more than two must be used.
The larger the contact angle, the higher the axial load capacity. For high-speed operation, however, smaller contact angles are preferred.
