Plastic coated bearing VS rubber coated bearing

Plastic-Coated Bearings:These bearings have a surface layer made of plastic material. The use of plastic coating can provide several benefits such as excellent corrosion resistance, good wear resistance, and self-lubrication properties. Plastic coatings can be chosen based on their ability to withstand different environmental conditions, including exposure to chemicals or extreme temperatures. This makes them suitable for use in environments where traditional lubricants cannot be used effectively, or where cleanliness is a priority.

Rubber-Coated Bearings:On the other hand, rubber-coated bearings are covered with a layer of rubber. Rubber coating offers unique advantages like enhanced vibration damping and noise reduction due to rubber's natural elasticity and sound-absorbing qualities. Additionally, rubber coatings can provide a high level of water resistance and protection against some types of corrosive agents. They are particularly useful in applications requiring high levels of shock absorption and quiet operation.

In summary, while both types serve to protect the bearing and enhance its performance, the choice between plastic-coated and rubber-coated bearings depends largely on the specific requirements of the application, such as environmental factors, operational noise levels, and the need for particular physical properties like elasticity or temperature resistance.
