What are the advantages and disadvantages of self-lubricating bearings?


Self-lubricating bearing is a type of bearing with excellent performance, which has been widely used in many fields. 
The following are the main advantages and disadvantages of self-lubricating bearings:

First, advantages: 
No lubrication, no maintenance: the lubrication problem is considered in the design of the self-lubricating bearing, so there is no need to add additional lubricant or regular maintenance in the process of use, which reduces the maintenance cost and workload. 
Long life and high reliability: due to its excellent wear resistance and corrosion resistance, the service life of self-lubricating bearings is relatively long, and its high reliability also ensures the stable operation of the equipment. 
Reduce noise and vibration: self-lubricating bearings produce less noise and vibration during operation, which helps to improve the working environment and equipment performance.

Simplify installation and reduce cost: the structural design of self-lubricating bearing is relatively simple and easy to install, and because of its maintenance-free characteristic, the cost of the whole equipment can be reduced. 
Suitable for a variety of working conditions: self-lubricating bearings can work normally in harsh environments such as high temperature, low temperature, high humidity, high corrosion and so on. 
Second, shortcomings: 
High cost: compared with traditional bearings, the manufacturing cost of self-lubricating bearings may be higher, which limits its application in some fields to a certain extent. 
High technical threshold: the design and manufacture of self-lubricating bearings require a higher technical level, which requires manufacturers to have the corresponding R & D and production capacity. 
There are certain requirements for the use environment: although the self-lubricating bearing can work in a variety of harsh environments, its performance may be affected in some extreme conditions. 
Self-lubricating bearings have many remarkable advantages, but they also have some disadvantages. 
When choosing whether to use self-lubricating bearings, it needs to be weighed according to the specific application scenarios and requirements.
