Principle of bearing lubrication The basis of bearing lubrication principle: elastic fluid dynamics theory. Question: Will the oil film be damaged by the load pressure? The thickness of the oil film depends on the viscosity of the base oil. The higher the viscosity, the thicker the oil film. Note: T... read more
There are significant differences between composite bearings and rolling bearings, so they cannot be used interchangeably. 1. Rolling bearings are often much more expensive than composite bearings due to their complex multi-component design, precision structure and precise installation.  ... read more
The working speed of rolling bearings mainly depends on their allowable operating temperature. Bearings with low friction resistance and low internal heat generation are suitable for high-speed operation. When only bearing radial load, deep groove ball bearing and cylindrical roller bearing can be u... read more
