A: Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an a...

A: The rigidity of a bearing is the amount of force required to produce a unit deformation of the bearing. The elastic deformation of rolling bearings is very small and can be ignored in most machines. However, in some machines, such as machine tool spindles, bearing rigidity is an important factor. Cylindrical and tapered roller bearings are generally used. Because the two types of bearings are s...

A： The so-called pre-tightening is to generate and maintain an axial force in the bearing in a certain way during installation, so as to eliminate the axial clearance in the bearing and produce initial deformation at the contact point between the rolling body and the inner and outer rings.Click here to view SUNBEARING rolling bearing.

A: Sealed bearing is a metal cover (dust cover) or a rubber ring with a skeleton embedded in the groove of the bearing ring (usually the outer ring), with a small gap or contact with another ring (usually the inner ring) to form a closed structure. Bearing with double-sided sealing can not only keep grease, but also prevent dirt and other foreign matters from entering the bearing and keep rolling ...

A: Bearing grease has the following main properties: 1) Thixotropy The most basic characteristic of grease is thixotropy. When an external force is applied, the flow of the grease gradually softens, showing a decrease in viscosity, but once at rest, the consistency increases again after a period of time (very short). This characteristic is called thixotropy. This characteristic of the grease deter...
