The main components or shell parts of plastic bearings are made of plastic materials. Traditional bearing shells are usually made of metal, while plastic bearings take advantage of the properties of plastic materials and have some special advantages , including:
1. Lightweight: Plastic materials are lighter than metal, so plastic bearings are usually lighter. This can be an advantage in some applications , such as where reduced overall weight or increased maneuverability is required.
2. No rust: Plastic is not prone to rust or corrosion, so plastic bearings do not need anti-corrosion treatment as often . This makes plastic bearings more suitable in some special environments, such as humid or corrosive environments .
3. Low friction: Plastic materials usually have a low friction coefficient, which helps reduce the energy loss of the bearing and improve efficiency. At the same time, low friction also means that plastic bearings generate relatively little .
4. Corrosion resistance: Plastic bearings can be used in environments that corrode metal bearings, such as chemical plants and food processing plants .
5. Low noise: Plastic bearings run less noisy than metal bearings, making them ideal for applications that require quiet operation, such as office equipment and home appliances
