Advantages of cylindrical roller bearings

1. The rollers and raceways are in line contact or trimmed line contact. They have large radial load-bearing capacity and are suitable for withstanding heavy loads and impact loads.

2. The friction coefficient is small, suitable for high speeds, and the limit speed is close to that of deep groove ball bearings.

3. 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.

4. The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis must be strictly controlled to avoid contact stress concentration.

5. The inner or outer ring can be separated for easy installation and removal.

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.
