Polymer plain bearings, specifically the composite self-lubricating red bushing without Pb, are a type of bearing that utilizes the unique properties of polymers and (Polytetrafluoroethylene) to provide smooth and efficient movement while minimizing wear and friction. These bearings are designed to operate without the need for external lubricants, making them ideal for applications where lubricant contamination or leakage is unacceptable.
The red composite material used in these bushings offers excellent chemical resistance and low coefficient of friction, resulting in long-lasting and reliable performance. The absence of Pb (lead) in the material ensures compliance with environmental regulations and safety standards.
These polymer plain bearings are commonly used in a wide range of industries, including automotive, aerospace, machinery, and more. Their ability to self-lubricate and operate efficiently under various conditions makes them a valuable addition to any mechanical system requiring smooth and reliable movement.

Product advantages:
Chemical properties
polymer surface resistance to chemical corrosion, so its corrosion resistance mainly depends on the steel back of plating and appearance. The steel back of tin or copper plated surface, can effectively prevent atmospheric corrosion; If you work in the corrosive medium, the steel back can be galvanized, etc.
