Angular contact ball bearing characteristics and rated speed

A: angular contact ball bearings feature:
    1. To face configure line towards the load bearing polymer bearing axis. Axial load carrying in both directions, although each is only by a bearing (or series bearing) load. Rigidity of this configuration is not back to back arrangement so high, is not suitable for the overturning moment.

    2. To configure the bearings back to back line towards the load bearing axis divergence. Can carry axial load in both directions, although each time only by a bearing (or series bearing) load. Back to back configuration relative rigidity to withstand overturning moment.

    3. Series bearings can not be compared with group group bearing or bearing adjustment, usually in series, and back to back, or a combination of serial and face to face configuration.

    Four. In the series configuration, bearing the load line is parallel. The average distribution of radial and axial loads on the bearings, but only in one direction axial load carrying. Therefore, a set of bearings in series configuration is usually relative to another can take the opposite direction to adjust the axial load bearing.

    2: Angular contact ball bearing Rated speed:

    Given in the table in the bearing speed limit reference value, these values in the load bearing less (P ≤ 0,06 C), bearing light through the spring pre-load applied, and bearing in good position in a heat transfer effect at the time.

    If using this method come to the group with enough speed rated bearings, you can simple design changes, such as into the ring gap between the bearing can achieve greater speed upgrade. To include three bearing bearing group, for example, can do it in pairs bearing the rated speed run. Applied for the pre-spring-bearing load may be useful. This type of pre-load commonly used for high speed applications, the purpose of the machine's entire operating range even within the pre-load.

    For oil lubrication of the value is the maximum point, the use of other methods of oil lubrication should be reduced according to the value speed. For grease lubrication is the maximum value. Both are suitable for single row bearings.

    When the single row bearing with each other a greater degree of adjustment (such as to improve spindle rigidity), or use two, three or four bearing, bearing group, should be reducing the value of the rated speed.
