Please Login Needle's official website www.zhgzzc.com governance and continue to understand the needle bearing theoretically impossible to realize the role of transmission, not only that NA4907 needle roller bearings, also affect the transmission, in order to reduce the impact on the high-speed shaft bearings must be achieved good lubrication, some bearing lubrication, called pre-lubricated bearings, and most of the bearing lubricant, otherwise at high speeds, due to the friction will not only increase energy consumption, even more frightening is very easy to damage the bearings
