What are the material advantages of PU deep groove ball bearings

Polyurethane (PU) is a polymer material synthesized by the reaction of isocyanate and polyol. It exhibits excellent physical and chemical properties due to its unique chemical structure. The molecular chain of PU material is rich in urethane groups, which gives it high strength, high elasticity, excellent wear resistance, and excellent oil resistance, water resistance and aging resistance. These characteristics make PU material show significant competitive advantages in the manufacture of deep groove ball bearings.

Material advantages of PU deep groove ball bearings
Excellent wear resistance
PU materials show extremely high wear resistance and can significantly reduce the wear rate during long-term operation. This feature enables PU deep groove ball bearings to effectively reduce friction resistance when subjected to high loads and high-speed operation, thereby reducing energy loss and improving the overall operating efficiency of mechanical equipment.
Self-lubrication
PU materials have excellent self-lubricating properties and can maintain a stable operating state in an oil-free or low-oil environment. This not only reduces the need for lubricants and reduces maintenance costs, but also enhances the operating stability and reliability of bearings, and meets the requirements of modern machinery for low maintenance.
Corrosion resistance
PU materials show good corrosion resistance to a variety of chemical substances and can maintain their stable performance in harsh environments such as moisture, acid and alkali. This feature makes PU deep groove ball bearings have a wide range of application potential in industries such as chemical and food processing, meeting the high requirements of these industries for material durability and safety.
Shock absorption and elastic recovery ability
PU materials' superior shock absorption and elastic recovery ability enable them to effectively absorb and disperse impact forces when subjected to impact loads, thereby protecting mechanical equipment from damage. At the same time, the elastic recovery ability of PU materials ensures that the bearings can still maintain good shape and dimensional stability after long-term operation, extending their service life.
Lightweight design
Compared with traditional metal bearings, the lightweight design of PU deep groove ball bearings significantly reduces the overall weight of mechanical equipment. This not only improves operating efficiency, but also reduces energy consumption, which is in line with the trend of modern industry for energy saving and consumption reduction.
