How does POM contribute to low friction and smooth operation in bearings?

POM (Polyoxymethylene), also known as acetal or Delrin, is a thermoplastic material widely used in bearings due to its ability to provide low friction and smooth operation. The unique properties of POM contribute to these characteristics in the following ways:

1. Low Coefficient of Friction:

POM has a low coefficient of friction, meaning it offers minimal resistance to sliding or rolling motion between surfaces. This property is advantageous in bearing applications as it reduces the energy loss due to friction and promotes efficient movement. The low coefficient of friction of POM is attributed to its molecular structure and the smoothness of its surface, which allows the bearing to operate with minimal resistance and heat generation.

2. Self-Lubricating Properties:

POM exhibits self-lubricating properties, meaning it has inherent lubricity without the need for additional lubricants. The molecular structure of POM allows for the formation of a thin lubricating film at the interface between the bearing and the mating surface. This lubricating film helps reduce friction and wear, resulting in smoother operation and extended service life of the bearing. The self-lubricating properties of POM make it suitable for applications where frequent lubrication or maintenance is impractical or undesirable.

3. Good Wear Resistance:

POM possesses good wear resistance, allowing it to withstand repeated sliding or rolling contact without significant material loss or surface damage. The material’s resistance to wear is attributed to its high hardness and low friction characteristics. POM bearings can maintain their dimensional stability and smooth surface finish even after prolonged use, ensuring consistent and reliable performance over time.

4. Low Moisture Absorption:

POM has low moisture absorption properties, which means it does not absorb water or moisture from the surrounding environment. This property is crucial in bearing applications as moisture absorption can lead to swelling, dimensional changes, and reduced performance. The low moisture absorption of POM helps maintain the dimensional stability and smooth operation of the bearing, even in humid or wet conditions.

5. Chemical Resistance:

POM exhibits good chemical resistance, making it resistant to various chemicals and solvents commonly encountered in industrial and environmental settings. This chemical resistance is beneficial in bearing applications where exposure to chemicals or aggressive substances may occur. The resistance of POM to chemical attack helps preserve the integrity and performance of the bearing, ensuring its smooth operation even in challenging environments.

Overall, the combination of low friction, self-lubricating properties, good wear resistance, low moisture absorption, and chemical resistance make POM an excellent choice for bearings. POM bearings offer reduced energy consumption, improved efficiency, and extended service life, contributing to low friction and smooth operation in various applications across industries.
