Deep groove ball bearings are suitable for high or even extremely high speed operations and are very durable without frequent maintenance. This kind of bearing has small friction coefficient, high limit speed, diverse size range and form, and is used in precision instrument, low noise motor, automobile, motorcycle and general machinery and other industries. It is the most widely used kind of bearing in the machinery industry.
Angular contact ball bearings can bear both radial and axial loads. Can work at higher rotational speed. The larger the contact Angle, the higher the axial bearing capacity. The contact Angle is the Angle between the contact point connection of the ball and raceway and the vertical line of the bearing axis in the radial plane. High precision and high speed bearings usually take a 15 degree contact Angle. Under axial force, the contact Angle will increase.
