Single row angular contact ball bearings can not only withstand radial load and axial load in one direction, but also accommodate only axial load in single direction, radial loads produce axial forces in these bearings that need to be balanced by counter forces.Therefore, the single row angular contact ball bearings often need to be installed with other bearings which withstand axial load in the opposite direction. In other words, the angular contact ball bearings are commonly used in pair, or in groups with three, four and even five bearings. Angular contact ball bearings have higher limiting speed.

The MONTON precision angular contact ball bearings for spindle, have four size series, 718,719,70 and 72. With the same inner diameter, but the outer diameter and the width of 718,719,70 and 72 series increase in turn.

MONTON precision angular contact ball bearings with 15° (C) and 25° (AC) contact angles. As for the angular contact ball bearings, the bigger the contact angle is, the greater the axial load capacity is, but the lower the limiting speed of bearings becomes. Therefore, the spindle, with high speed and small axial load, should adopt the 15° angular contact ball bearings, whereas the 25° angular contact ball bearings should be adopted.

MONTON precision angular contact ball bearings with high-speed angular contact bearings (standard series), super high-speed angular contact ball bearings, high-speed sealed angular contact ball bearings and high-speed spindle bearings.

The inner ring, outer ring and rolling element of rolling bearing under normal operating conditions are made of high carbon chromium bearing steel, but the steel bearings cannot meet the requirements of such special conditions as high speed, wear-resisting, low temperature rising, long life and high reliability etc., then Si3N4 ceramics are believed to be present optimum rolling bearing materials to replace bearing steel.

MONTON also offers widely used hybrid angular contact ball bearings for spindles in high-speed precision machine tools and other high-speed precision machines, that is, the inner and outer rings are made of high-quality bearing steel materials, while the rolling element is made of Si3N4 ceramics.

Compared to the angular contact ball bearings made of steel, hybrid angular contact ball bearings with the same structure and size have high speed, high stiffness, low friction heat, and long life etc.

MONTON precision hybrid bearings with ceramic ball (HQ1) can significantly improve the speed, rigidity, reliability, and productivity of machine tools, and greatly reduce the friction heat, then extend the service life of host machine etc.
