What is the NTN bearing friction moment? If according to the friction torque entrance NTN bearing selection? These are not difficult to understand and grasp, today we together to share this knowledge about.
The friction of NTN bearing is mainly composed of a moving body and the raceway of the friction and sliding friction between the move; the holder and the dynamic ring body and the sliding friction between the guide surface (no holder for sliding friction between the moving projectile); sliding friction between roller end and the ring gear side surface of the viscous resistance of the lubricant; sliding friction sealing device; aspects of composition, which depends on the type, in the NTN bearing size, speed, load, lubrication, sealing and other factors.
On the NTN bearing selection, we recommend you to look "careful judgment entrance NTN bearing on the quality of some misunderstandings of" introducing this article.
In the instrument and machinery to be low friction torque, usually choose NTN deep groove ball bearings, cylindrical roller bearings, self-aligning ball NTN NTN bearings, to bear radial load; selection of single row thrust ball bearing NTN bearing NTN to load, if subjected to combined loads, can choose the angular contact ball bearing in NTN, load angle and contact angle can be obtained when the basic consistent, the friction torque minimum; if the two corners of the gap is too big, can choose the radial and thrust bearing assembly solutions to NTN.
NTN bearings use low friction torque, the design should avoid the use of sealing device for contact type. At the same time, lubrication NTN bearing on the low friction moment, should use the lubrication, oil mist lubrication and oil air lubrication.
