What are the advantages of self-lubrication of PU deep groove ball bearings

Self-lubrication refers to the property that materials can generate lubrication effects autonomously during friction. This property significantly reduces friction resistance and wear, thereby extending the service life of the product. For bearings, the realization of self-lubrication can not only reduce dependence on lubricants and reduce maintenance costs, but also maintain a stable operating state under extreme environmental conditions, thereby improving the reliability and safety of mechanical equipment.

Advantages of self-lubrication of PU deep groove ball bearings
Significant reduction in friction coefficient
Polyurethane (PU) materials have a low friction coefficient and can self-generate lubrication effects during friction, significantly reducing the friction resistance between bearings and shafts. This feature not only effectively reduces energy consumption, but also improves the overall operating efficiency of mechanical equipment.
Reduced use of lubricants
Traditional metal bearings usually require regular addition of lubricants to ensure normal operation, while PU deep groove ball bearings can operate stably in oil-free or low-oil environments due to their excellent self-lubricating properties. This feature significantly reduces the frequency of lubricant use, thereby reducing maintenance costs and reducing labor and material input.
Improved wear resistance
The superior wear resistance of PU materials enables deep groove ball bearings to maintain a low wear rate during long-term operation. This feature enables PU deep groove ball bearings to maintain good operating conditions under harsh working conditions, thereby extending the service life of the product and reducing the economic losses caused by frequent bearing replacement.
Reduced noise and vibration
The self-lubricating property makes the bearings more stable during operation, significantly reducing the noise and vibration caused by friction. This not only improves the comfort of mechanical equipment, but also reduces interference with the surrounding environment, helping to improve the work efficiency of the operating environment.
Strong adaptability
The self-lubricating property of PU deep groove ball bearings enables them to maintain a stable operating state in a variety of complex environments, including extreme working conditions such as high temperature, low temperature, and humidity. This feature makes PU deep groove ball bearings widely used in many industries, such as automobiles, aviation, and machinery manufacturing.
