What are Class I bearings and Class II bearings?

Compared with large machinery, the bearing is a small component, but it plays a pivotal role. And it is mainly a component that fixes and reduces the friction coefficient of the load during the mechanical transmission process. When other parts move relative to each other on the shaft, the bearing can be used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. According to the different friction properties of moving elements, bearings can be divided into rolling bearings and sliding bearings.What is the difference between a first-class bearing and a second-class bearing?

A class of bearings, self-aligning ball bearings, are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, paper, cement, sugar and other industries and general machinery wait.

The second type of bearings, that is, cylindrical roller bearings, are mainly used in motors, machine tools, petroleum, rolling mill loading and unloading machinery and various industrial machinery. It is a separable bearing, which is very convenient to install and disassemble. Cylindrical roller bearings are divided into single row, double row and four row. Single row cylindrical roller bearings are divided into N type, NU type, NJ type, NF type and NUP type according to the different ring ribs. Cylindrical roller bearings have a large radial load capacity, and can also bear certain one-way or two-way axial loads according to the structure of the ring rib.
