How to choose the right bearing and the common sense of the 2206 bearing

wallpapers News 2021-07-14

Why do we need to know the common sense of using 2206 bearing?

Bearing users very much hope that the bearings installed on the main engine will not be damaged and maintain their dynamic performance during the predetermined period of use. However, the objective facts are sometimes not satisfactory. Sudden bearing failure accidents will cause heavy losses to users. A large number of bearing failure analysis studies have shown that the 2206 bearing has a short life or premature loss of accuracy, some of which are due to material defects or improper manufacturing, but to a considerable extent, it is due to not strictly in accordance with the requirements of bearing use for installation and maintenance. Or the bearing is abnormally damaged due to improper selection of the bearing or the actual load exceeding the rated load of the bearing itself. For example, the fatigue spalling of 2206 bearing parts is largely caused by impurities mixed in the lubricating oil. It can be seen that in order to achieve a longer life and accuracy retention period for rolling bearings, in addition to requiring bearing manufacturers to improve product quality, 2206 bearing users must also use scientific methods and procedures to use 2206 bearing, otherwise, even the best 2206 bearing will be Damaged under harsh conditions of use.

Steps to select bearings

1. According to bearing working conditions (including load direction and load type, speed, lubrication method, coaxiality requirements, positioning or non-positioning, installation and maintenance environment, ambient temperature, etc.), select the basic type of bearing, tolerance level and clearance;

2. Determine the bearing model through calculation according to the working conditions and stress conditions of the bearing and the life requirements, or select the bearing model according to the use requirements, and then check the life;

3. Check the rated load and limit speed of the selected bearing.

The main considerations for selecting a bearing are the limit speed, required life and load capacity. Other factors help determine the final plan of bearing type, structure, size and tolerance level and clearance requirements. If you have other questions, please feel free to consult sales@spark-bearing.com.

How to use all kinds of bearings appropriately?

Generally speaking, deep groove ball bearings, angular contact bearings, and cylindrical roller bearings should be selected for higher speed working occasions; for lower speed working occasions, tapered roller bearings can be selected. The limiting speed of tapered roller bearings is generally about 65% of deep groove ball bearings, 70% of cylindrical roller bearings, and 60% of angular contact ball bearings. Thrust ball bearings have a low limit speed and can only be used for lower speed occasions.

What are the factors related to the service life of the 2206 bearing?

The size of the 2206 bearing and the load of the 2206 bearing directly affect the service life of the 2206 bearing. Generally, the selection step of the 2206 bearing is to preliminarily determine the required bearing according to the load, and then according to the products in the product table, as well as possible occurrences. Maximum load, static load not only refers to the load acting on the bearing at rest or very low speed (n<10r/min), but also the static load safety factor under heavy shock load (load acting in a short time).

In the rated life formula of the 2206 bearing, other external forces need to be considered, including lubrication, surface smoothness, etc., and these conditions are combined to consider its actual service life. For the rolling contact surface, metal fatigue is the main cause of damage.

The 2206 bearing is a micro working system, and the actual service life depends on the first damaged component, so the ideal state is that all components reach the end of their service life at the same time. According to the previous bearing damage data, metal fatigue is the most important damage factor. You can consult sales@spark-bearing.com for knowledge about bearings at any time.
