Structure and characteristics of rolling bearing

Rolling bearing is a kind of precise mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thus reducing the friction loss.Rolling bearings include raceways (inner and outer rings), rolling bodies (balls or rollers) and cages. Through the cages, the rolling bodies are kept at a certain distance and fixed in the correct position for movement. The conta...

What factors will affect the life of the high-speed motor bearing shaft

High-speed motor bearings have higher precision and smaller surface roughness than ordinary bearings. The intuitive difference is that the surface of high-speed motor bearings is smoother than that of ordinary bearings. If the outer ring and inner ring shake, the clearance of the high-speed motor bearing is small.1. What to do if the bearing of the high-speed motor is overloaded and heated1. In the case of high speed...

What is the role of the cage in the motor bearing

Cage (namely bearing cage, also known as bearing retainer) refers to the bearing parts that partially wrap all or part of the rolling body and operate with it, which is used to separate the rolling body. Generally, it also correctly guides the rolling body and controls it in the bearing. Next, briefly introduce the main functions of the lower cage.During the operation of rolling motor bearings, especially when the lo...

Understand how to select bearing model and specification for motor model

The selection of motor bearings can be carried out as follows:1. Select according to the limit speed. In the bearing table, all bearings are the main parameters with the limit speed. It is only necessary that the shaft speed does not exceed the limit speed of the bearing.2. It is determined according to the load on the shaft. In the bearing table, all bearings list the main parameters of "rated dynamic load" and "rat...

Lubrication requirements of motors for motor bearings

The lubrication of motor bearings is mainly related to the temperature of the motor’s operating environment and its own temperature. Generally, 2# and 3# lithium-based greases are sufficient for motors. If it is a smoke exhaust motor or needs to be operated in a high temperature environment, ABB motors refer to 7017-1B with high viscosity and high temperature lubrication is required. There are a few main points to no...
