For plastic materials, metal bearings are more convenient to process, have strong impact resistance, and have a variety of materials, which can be used in most equipment. Moreover, the self-lubricating bearing of Viiplus does not require additional oil, which saves the cost of oil.
Compared with metal bearings, plastic bearings have low density and light weight, which can reduce the energy consumption caused by rotation during operation. They are suitable for light equipment, have low production costs, can be mass-produced, save production costs, wear resistance, and cooperate with equipment. flexibility. Disadvantages: not resistant to high temperature, poor mechanical properties, low speed, etc.
