Design Principles

Ceramic plastic bearings typically refer to bearings whose rolling elements (balls or rollers) are made of ceramic materials (such as silicate ceramics, silicon nitride, zirconium oxide, etc.), while the inner and outer rings are made of high-performance plastics (such as polyimide, polyetheretherketone PEEK, etc.). The design principle is to combine the advantages of both ceramic and plastic materials to meet the needs of certain special applications.

Performance Features

Ceramic plastic bearings have the following performance features:

Corrosion resistance and chemical stability: Both plastics and ceramics have excellent chemical corrosion resistance, suitable for use in harsh chemical environments.
Non-magnetic and insulating: Suitable for applications in strong magnetic fields or where insulation is required.
Lightweight and wear-resistant: Ceramic rolling elements are lighter than metal, and ceramic materials are hard and wear-resistant.
Low friction coefficient: Ceramics and some plastics have a low coefficient of friction, which can provide smoother operation and reduce heat generation.
Service life: Under proper conditions, ceramic plastic bearings may have a longer service life than traditional metal bearings.
Temperature range: Capable of operating over a wider temperature range, especially since high-performance plastics can withstand higher temperatures.

Application Scenarios

Ceramic plastic bearings are suitable for the following scenarios:

Food processing: Due to their corrosion resistance and no need for lubrication, they are suitable for environments with high cleanliness requirements.
Medical equipment: Non-magnetic and clean characteristics make them suitable for medical imaging equipment like MRI.
Chemical industry: Chemical and corrosion resistance properties are suitable for handling chemical substances.
Electronics manufacturing: Insulating properties make them suitable for preventing electrical interference.
High-temperature applications: Heat-resistant plastic materials are suitable for environments with higher temperatures.
Submarine or underwater applications: Corrosion resistance makes them suitable for use in seawater or other corrosive liquids.
