Due to material differences, bearing products are divided into plastic and metal types. Although the basic functions in actual work are the same, in the end they are two different types of bearing products. It can be seen that there is still a big difference.
1.Performance
Even if plastic bearings are used in harsh environments, they will not be affected by environmental factors and cause abnormal phenomena such as rust and corrosion. This aspect cannot be guaranteed for metal bearings, because metal can easily react with acids, alkalis, etc., causing rust.
2. Quality
Obviously, the weight of plastic must be lighter than that of metal, so the plastic bearings produced are also more advantageous in terms of quality and can better meet the design standards of lightweight products.
3. Craftsmanship
Generally, plastic bearings are produced and processed by injection molding. The simple process is particularly suitable for the production and processing of large-volume products, while metal bearings require casting and other related processes. The complexity makes metal bearings unable to achieve mass production. standard.
4. Period of use
The excellent performance, coupled with the fact that the entire bearing is made of lubricating materials, results in plastic bearings having a long service life. However, if the lubricating material on the surface of metal bearings is rubbed out, the service life will be affected.
