When choosing bearings, people often encounter paired bearings that need to be purchased. So, what about bearing pairing? Today, Li Gong Bearing will talk to you about the knowledge of bearing matching, hoping that LIGZZ Li Gong Bearing can be helpful for your bearing selection.

CA, CB, CC - Universal paired single row angular contact ball bearings, can be installed in any (series, face-to-face or back-to-back) pairing. When arranged back-to-back or face-to-face, the internal clearance before axial installation is smaller than the normal value (CA), normal (CB), and larger (CC).

-2F - Outer spherical ball bearing with dust retaining rings on both sides.

-2FF - The outer spherical ball bearing is equipped with combined dust retaining rings on both sides.

G - Universal paired single row angular contact ball bearings. When arranged face-to-face or back-to-back, there is a certain pre installation preload inside the bearings.

GA - When arranged face-to-face and back-to-back, there is a lighter preload inside the bearings.

When arranged face-to-face and back-to-back, there is a moderate preload inside the bearings.

Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of moving components, bearings can be divided into two categories: rolling bearings and sliding bearings. Rolling bearings have been standardized and serialized, but compared to sliding bearings, they have larger radial dimensions, vibration, and noise, and are also more expensive. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element, and retainer. Strictly speaking, they are composed of six major components: outer ring, inner ring, rolling element, retainer, seal, and lubricating oil. The main features include the outer ring, inner ring, and rolling element, which can be defined as rolling bearings. According to the shape of the rolling element, rolling bearings are divided into two categories: ball bearings and roller bearings. LIGZZ Li Gong Bearing

Li Gong Bearing would like to introduce some common knowledge about bearing configuration to you, which may be helpful:

Number code in the bearing configuration group
