Why Choose POM for Bearing Assemblies?

POM (Polyoxymethylene), also known as Acetal, is widely used in engineering applications because of its outstanding mechanical properties.

Key advantages include:

• Low coefficient of friction
• Excellent dimensional stability
• High wear resistance
• Lightweight construction
• Low operating noise
• Corrosion resistance
• Moisture resistance
• Long service life

These characteristics make POM an excellent choice for rotating components where smooth motion and durability are essential.
