The NJ2206 Cylindrical Roller Bearing is a high-performance bearing designed to support heavy radial loads while also allowing limited axial load in one direction. Its NJ-type structure includes a fixed inner ring rib and a loose outer ring rib, providing excellent guidance and stability during operation.
Manufactured from premium chrome steel and available in stainless steel and special material options, the NJ2206 bearing delivers high rigidity, low friction, and long service life. It is widely used in industrial machinery where reliability, load capacity, and precision are critical.
Thanks to its separable design, the NJ2206 bearing is easy to install, inspect, and maintain, making it suitable for demanding mechanical systems operating under continuous load conditions.
