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
In most operating conditions, rolling bearings are used with proper clearance. According to different purposes, there are also internal stresses that are generated in advance when the bearing is installed, so that the bearing can be used under negative clearance. This method of use is called preload... read more
