Characteristics of angular contact ball bearings

The special feature of angular contact ball bearings is that there is a contact angle between the ring and the ball. The standard contact angles are 15°, 30° and 40°. The larger the contact angle, the greater the axial load capacity. The smaller the contact angle, the greater the axial load capacity. It is conducive to high-speed rotation; single-row bearings can bear radial load and one-way axial load; DB combination, DF combination and double-row bearings can bear radial load and two-way axial load; DT combination is suitable for large one-way axial load. When the rated load of a single bearing is insufficient.

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.
