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
The main heat-generating components of the motor are generally windings and bearings. Specific temperature abnormalities on the surface are generally divided into the following categories: bearing temperature is too high, winding temperature is too high, chassis temperature is too high, etc. ... read more
