Product description of KOYO Bearing 7311CDT

KOYO Angular contact ball bearings Matched pair Tandem,KOYO Bearing 7311CDT, the angular contact ball bearing is suitable for applications demanding high accuracy and high rotational speed and is capable of withstanding combined radial and axial loads.

Angular contact ball bearings are suitable for applications which require high accuracy and good high-speed Performance. This type of bearing is designed to carry a combined load.

■Single-row angular contact ball bearings and matched pair angular Contact angle contact ball bearings
●The standard contact angles are 15*, 30° and 40*. They are identified, respectively. By the supplementary codes ^C"',"A" (omitted) and "B". Bearings with a smaller contact angle are more suitable for applications involving high-speed rotation.Those with a larger contact angle feature superior axial load resistance.
●Angular contact ball bearings are gotten preload-ed to enhance their rigidity and rotating performance.(refer to p. A 106.) For high-precision matched pair angular contact ball bear-rings or class 5 or higher, which are used in machine tools and other precision equipment, the standard preload is Specif-led in three levels: slight (S). light (L). medium (M)and heavy (H)(refer to Table 11-2 on p. A 108.)
●When this type of bearing is loaded radially, an axial component of force is produced. In this case, two bearings are used together facing one another, or two or more bearings are matched and used. (refer to p. A 34.)
●Tables 1 and 2 list the different types of single-row and matched pair/slack angular contact ball bearings and describe their characteristics.
■ KOYO Bearing 7311CDT, Angular contact ball bearings Matched pair Tandem. Consist of two single-row Angular contact ball bearings Matched pair Tandem, with inner and outer rings integrated. Table 3 shows major types and their characteristics.
■Four-point contact ball bearings
●Have a contact angle of 35° and an inner ring Divided into two annular pieces. They are suitable for applications that involve either axial loading or combined load . where the axial load makes up the major part of the load,
●Able to support both axial load and a certain degree of redial load. Each rolling element is in contact with each of the inner and outer rings at a single point, and both contact points lie on the contact angle line. The line runs to either the right or left depending on the direction of the axial load.
●Carl-es radial load and axial load in one direction.
●Suitable for applications which involve a high degree of axial loading.
