Self lubricating bearing

Self lubricating bearing 1 has no oil lubrication or less oil lubrication, and can be used without maintenance or with less maintenance. 2. Good wear resistance, low friction coefficient, and long service life. 3. With an appropriate amount of elastic-plastic properties, it can distribute stress over a wider contact surface and improve the bearing capacity. The static and dynamic friction coefficients are similar, thus ensuring the working accuracy of the machinery.

Self lubricating bearing 1 has no oil lubrication or less oil lubrication, and can be used without maintenance or with less maintenance. 2. Good wear resistance, low friction coefficient, and long service life. 3. With an appropriate amount of elastic-plastic properties, it can distribute stress over a wider contact surface and improve the bearing capacity. The static and dynamic friction coefficients are similar, thus ensuring the working accuracy of the machinery. 5 can reduce mechanical vibration, reduce noise, prevent pollution, and improve labor conditions. During operation, a transfer film can be formed to protect the grinding shaft. 7. Low hardness requirements for grinding shafts reduce the difficulty of machining related parts. 8 thin-walled structure, lightweight, can reduce mechanical volume. The back of 9 steel can be electroplated with various metals and can be used in corrosive media; It has been widely used in various sliding parts of machinery.
