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
To ensure the reliable operation of rolling bearings, adequate lubrication is necessary. Bearing lubrication methods are roughly divided into two types: grease lubrication and oil lubrication. How to give full play to the function of the bearing, the key is to use the appropriate lubrication method ... read more
