The difference in material is divided into plastic and metal bearing products. Although the basic function is the same in actual work, it can be seen that there are still great differences between the two kinds of bearing products. You can distinguish them from the following:

 

1. Quality

It is obvious that the weight of plastic must be lighter than that of metal, so the plastic bearings manufactured from it are also more dominant in quality and can meet the design standards of lightweight products.

 

2. The process

General plastic bearings are produced and processed by injection molding, and the simple process is especially suitable for the production and processing of large quantities of products, while metal bearings need to be cast and other related processes, resulting in the complexity of metal bearings can not reach the standard of mass production.

 

3. The performance

Even if plastic bearings are used in harsh environments, they will not be affected by environmental factors, resulting in rust, corrosion and other abnormal phenomena. And metal bearings can not be guaranteed in this respect, because metal is easy to react with acid and alkali, causing rust.

 

4. Term of use

The excellence of the performance level, coupled with the fact that the whole is made of lubricating materials, causes plastic bearings to have a long service life, while the service life of the lubricating materials on the surface of metal bearings will be affected if they are rubbed
