Copper bearing installed with graphite lubrication column and scattered graphite lubrication columns.
Description

Graphite lubrication column is a solid lubricant, typically made of high-strength and high-purity graphite. Its main role in embedded copper bearings is to reduce friction and wear of the copper bearings. Bearings are an important part of mechanical equipment, and their main function is to support and rotate mechanical parts, enabling the normal operation of the machinery. By using graphite lubrication columns, the performance of copper bearings can be improved, thereby extending their service life and reducing the frequency of maintenance and replacement required.

Features

Using graphite lubrication column in cooper bearings can have the following functions.

  • Reduce the friction of copper bearings. Copper bearings generate friction during operation. Using graphite lubrication columns can reduce the friction of copper bearings, thus reducing energy consumption and heat generation.
  • Reduce the wear of copper bearings. Copper bearings tend to wear out over time. Using graphite lubrication columns can effectively reduce the wear of copper bearings and extend their service life.
  • Improve the efficiency of copper bearings. Using graphite lubrication columns can reduce the friction and wear of copper bearings, thus improving their efficiency and performance.
