The ball bearing changes the friction mode of the bearing and adopts rolling friction, which more effectively reduces friction between the bearing surfaces, improves the life of the fan bearing, thus extending the life of the cooler. The disadvantage is that the procedure is more complicated, the costs increase and it also entails higher working noise.
What are the main components of ball bearings?
What is the main difference between ball bearings and roller bearings?
How do I choose grease for ball bearings?
Ball bearings consist mainly of four basic elements: ball, inner ring, outer ring and cage, also called cage or cage. General industrial ball bearings meet the AISI 52100 standard. The balls and rings are usually made of high chromed steel, and the Rockwell hardness on the C scale is about 61-65. The hardness of the cage is lower than that of the ball and ring, and its material is metal (e.g., medium carbon steel, aluminum alloy) or non-metal (e.g., Teflon, PTFE, polymer material). Ball bearings have lower rotational friction resistance than plain bearings, so that the temperature generated by friction is lower at the same speed.
1. Ball bearing: The alloy steel spherical ball is installed in the middle of the inner steel ring and outer steel ring to reduce the friction during the power transmission process and improve the transmission efficiency of mechanical force by rolling. ball bearings cannot withstand heavy loads and are more common in light industrial machines.
2. Roller bearing: It is a kind of bearing. As the cone rotates, it touches in the circumferential direction many rollers that are normally installed on the position ring. The rolling bearing can achieve good precision and rigidity by preloading. A conical inner ring can also be used.
Lubrication has a very important influence on the operation and service life of ball bearings. Here is a brief introduction to the general principles of fat selection. Grease consists of base oil, thickeners and additives. The performance of different types and different brands of fats of the same type is very different, and the permissible rotation limits are different. Be careful when choosing. The performance of lubricating greases is largely determined by the base oil. Generally, the low viscosity base oil is suitable for low temperatures and high speeds, and the high viscosity base oil is suitable for high temperatures and high loads. The thickener is also related to the lubrication performance, and the water resistance of the thickener determines the water resistance of the grease. Fats of different brands are basically not miscible, and even fats with the same thickener have a negative effect due to different additives.
In many places of our daily life, we see the shadow of ball bearings. At Shandong Xuanye Precision Machinery Co., Ltd., you will get the best quality ball bearings and the most intimate after-sales service.
