Role and requirements of rolling bearings

The role of rolling bearing coordination is to make the stationary ring and the rotating ring of the bearing respectively consolidate with the stationary part (usually the bearing seat) and the rotating part (usually the shaft) of the installation site, so as to realize the load transmission and the limited movement in the rotating state.

The basic task of the system with respect to the position of the stationary system. On the shaft and in the housing, the rolling bearing is required to fix its position in three directions: radial, axial and tangential directions. Radial and tangential positioning is achieved through tight fitting of the bearing rings.

The axial positioning is only used in a few cases with tight fit; axial limiting parts such as end caps and retaining rings are generally used to limit the axial position. In the clearance range.

When choosing a fit, you should pay attention to the following four points:

(1) The circumferential surface of the bearing ring should be well supported and subjected to even force so as to reduce deformation and give full play to the bearing capacity.

(2) The ferrule cannot slide in the tangential direction in its mating surface, otherwise it will damage the mating surface.

(3) The free end bearing must be able to adapt to changes in the length of the shaft and the housing bore, ie it must have the ability to accommodate axial movement within a certain range.

(4) It must be noted that it is easy to install and disassemble the bearings, saving time and money.

Huatao Bearings included Rolling Bearings, Thrust Bearings, Slewing Bearings, Joint Bearings. They are widely used in Industrial Gearboxes, Electric Motors, Industrial Rollers.
