Background technique

Sliding bearings are widely used in various fields because of their high bearing capacity, good shock resistance, stable and reliable operation, low noise, and long life.

As a basic component, sliding bearings are widely used in various machinery. At present, sliding bearings are generally cooled by natural cooling or forced air cooling. The natural cooling efficiency is not high. As the diameter or speed increases, the natural cooling becomes more It is increasingly unable to meet the heat dissipation needs of sliding bearings. Forced air cooling requires the help of external equipment, which increases the bearing structure and makes the structure complex. To this end, we propose a polymer material sliding bearing.
