Insert bearings are widely used in industrial equipment, and lubrication is essential for their reliable operation. Grease lubrication is the most common lubrication method for insert bearings. Its advantages include simple operation, long maintenance cycle and good sealing effect.
Choosing the right grease is essential to ensure the efficient operation of insert bearings. Different working conditions, such as temperature, load, speed and environmental factors, all put forward different requirements for the selection of grease.
Base oil type
Mineral oil: This is the most common type of base oil and is suitable for most medium and low temperature and medium load applications. Mineral oil is low in price and stable in performance, suitable for general industrial use.
Synthetic oil: Synthetic oil has better thermal stability and oxidation resistance, and is suitable for high temperature, high speed or very low temperature environment. Synthetic grease is often used in harsh application conditions such as aerospace and high-precision machinery.
Bio-based oil: With the improvement of environmental awareness, bio-based greases have become an option, especially in places with strict environmental requirements. They are renewable and have less impact on the environment.
Thickener type
The thickener determines the consistency and stability of the grease. Common thickeners include:
Lithium soap: This is the most common type of thickener, with good water resistance and mechanical stability, suitable for most industrial applications.
Lithium complex: It has better high temperature performance and oxidation resistance than single lithium soap grease, suitable for environments with large temperature fluctuations.
Calcium soap: It has excellent water resistance and corrosion resistance, suitable for environments with high humidity and moisture contact, such as the paper industry.
Polyurea: It is suitable for high temperature and long life applications, usually used in heavy machinery or high-speed motors.
