Angular Contact Ball Bearing

  • Single Row Angular Ball Bearings

    Single-row ball bearings with oblique joint are non-demountable. They are manufactured in multiple series. They are characteristic with low friction, high rigidity and silent run. The bearings are suitable for high rpm.
    Single-row ball bearings with oblique joint have the bearing ring orbits designed so that the joins of their points of interface with balls contain acute angle – the so-called contact angle – with the perpendicular on the bearing axis. These bearings can transmit radial and axial forces simultaneously. Axial forces are only transmitted in one direction. Thrust duty increases with growing contact angle. Through suitable arrangement of a couple of bearings, dual axial load-carrying capacity can be achieved.
    The bearings are manufactured with normal accuracy, for seating more demanding in terms of accuracy, or seating with higher rpm frequency, bearings with higher running accuracy are used.

  • Double Row Angular Contact Ball Bearings

    Double Row Angular Contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate and simultaneously action axial and radial loads. Due to angular contact, the axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. These bearings can accommodate thrust in both the directions. The chief advantages of the double row type are rigidity, compactness and high capacity.
