Angular Contact Ball Bearing Characteristics

Angular contact ball bearing is radial thrust ball bearing. Due to it can be put in more balls, so that it's radial load capability is larger than ordinary ball bearing's, and can bear large axial load or subject to pure axial load. Angular contact ball bearing allows the working speed is close to deep groove ball bearing working speed, but with stronger support rigid; and requires accurate installation, for it is sensitive to axis misalignment error.It generally doesn't bear radial load alone, while when bears radial load it will bring additional axial load at the same time. This bearing has lots variant varieties and is widely applied. It is usually made with 15°, 25° and 40°the three contact angle series.The larger the contact angle is, the higher the axial load capacity will be, but it's better use small contact angle in the high-speed situation. Most of these bearings are used in small-span rigid double supporting shaft bearings or the precision spindle in pairs. And the bearing clearance should be adjust well before using. Change the bearing's inner, outer radial distance can adjust the bearing internal clearance. At the same time parallel install several sets of bearings and give them certain amount of pre-interference fit, this can improve the rigidity of the bearing systems. Single of this type bearing can only bear the axial load of a direction, it needs the other bearing configuration to offset the additional axial force; while when mounted in pairs the additional axial force can be counteracted, and the bearings can bear axial loads come form two direction or more, and have a strong axial limit capacity of two direction. Paired mounting generally use two sets of bearings and use the outer ring width end face relative( Back To Back) or narrow end face relative ( face to face) two installation methods, and the back-to-back mounting bearing system own the best rigid amoung the two methods. For easy installation in pairs or groups, some bearing factory supplied bearings in pairs, in group of three or four sets. For the supplied bearing with same batch have good processing consistency,  when using, the angular contact ball bearings can bear the load more evenly, and can cancel each other the additional axial force out more thoroughly.
