Custom NK Series Needle Roller Bearing Manufacturers, Factory

NK Series

NK series needle wheel bearings are bearings with high load-bearing capacity and small size, and are widely used in various mechanical equipment. Its structural feature is that the inner ring is missing, allowing greater loads to be carried in a limited space. This bearing provides low friction and excellent motion performance by using high-strength needle rolling elements between the inner and outer rings. The NK series bearings have a simple design and are easy to install. They are suitable for high-speed operation environments and can effectively reduce noise and vibration. They are commonly used in automobiles, industrial machinery, aerospace and other fields to improve the efficiency and service life of equipment. Due to their excellent load-carrying capacity and fatigue resistance, NK series needle wheel bearings have become an important choice in modern engineering applications.
