Angular Contact Ball Bearing

719 Series Angular Contact Ball Bearings

The 719 series angular contact ball bearing is particularly suitable for applications with high stiffness requirements because it contains the most significant number of balls relative to its inside diameter and can accommodate the largest shaft diameter relative to its outside diameter. These two characteristics are substantial for the stiffness of the system. With the increase of the shaft diameter, the stiffness of the shaft increases, and with the rise of the number of balls, the stiffness of the bearing also increases.

As one of the angular contact ball bearing manufacturers, suppliers, and exporters of mechanical products, We offer angular contact ball bearing and many other products.Please get in touch with us for details.

As Shown In The Above Structure:

719 series is the ultra-light series among angular contact ball bearings;

70 series is the light series among angular contact ball bearings;

72 series is the strengthening series among angular contact ball bearings;

Application of Angular Contact Ball Bearing:

Different working conditions can be combined in many ways to obtain the different bearing capacities of radial and axial load and meet the requirements of high speed, diameter, and high axial stiffness. Therefore, it is widely used in the spindle of precision machine tools.

719 or 70 series bearings should be selected when the rotating speed is high, or the radial installation space is small; for heavy loads and relatively low speeds, 72 series bearings are more suitable.
