What is the stress on tapered roller bearings?

Tapered roller bearings can be separated, and the assembly consisting of the inner ring, rollers and cage and the outer ring can be installed separately. Corrected contact lines at the roller and raceway contact reduce stress concentrations. Tapered roller bearings can bear large radial loads and axial loads. Since tapered roller bearings can only transmit axial loads in one direction, another tapered roller bearing installed symmetrically is required to transmit axial loads in the opposite direction.
Usually, the cone angle of the outer ring raceway of a single row tapered roller bearing is within 10°~19°, which can withstand the combined effects of bearing directional load and radial load at the same time. The larger the cone angle, the greater the ability to withstand axial load. Bearings with large cone angles have a suffix code of B. The cone angle is between 25° and 29°. They can withstand large axial loads. In addition, single row tapered roller bearings can adjust the clearance during installation.

This type of bearing generally does not allow the shaft to tilt relative to the housing hole, and the maximum cannot exceed 2'

What is the function of bearings?

Function: Bearings are an important part of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during movement, and ensure rotation accuracy.

What material is bearing steel?

The hardness of bearing steel is relatively high, and this material is also relatively wear-resistant. Moreover, the chemical composition of bearing steel is very balanced, and the requirements for the distribution of various substances inside are very strict, especially the distribution of carbides.

How to maintain cylindrical roller bearings

During the entire cleaning process of cylindrical roller bearings or after assembly, there is also a large inspection process to be carried out. Some of them are to inspect the quality of cylindrical roller bearings, and some are to inspect the quality indicators of finished bearings. These inspections are very necessary and strict.

Advantages of cylindrical roller bearings

N type and NU type can move axially, can adapt to changes in the relative position of the shaft and housing caused by thermal expansion or installation errors, and can be used as free end supports.
