Bearing speed is quite fast, slow and fast, the internal friction bearing, mainly is the limitation of the bearings in the speed of temperature rise, so when the speed exceeds limit bearing will no longer continue to rotate over time due to excessive friction, bearing of the limit speed means not to produce friction heat burns, and can, therefore, the threshold of the continuous rotation bearing limit speed, is depend on the type of bearings, including the precision of size, and also the way and lubrication, the quality of the lubricant must keep with the type of bearing is the same.
All kinds of bearing with grease lubrication and oil lubrication, this time the limit speed respectively in each bearing the size of the table, including numerical representation standard design of the bearing under general load adjusting rotation speed limit value, in addition, the lubricant according to certain types of brand, also can lead to performance degradation, when fixing the limit speed we also want to do a lot of related problems, these problems are the problems of manufacturer, with more senior teacher, to discuss.
