The NJ311ECP cylindrical roller bearing is a high-performance radial bearing designed to accommodate heavy radial loads and moderate axial loads in one direction. The "NJ" designation indicates that the bearing has one flanged outer ring and a cylindrical inner ring, which allows for axial displacement of the inner ring within certain limits. This design makes it ideal for applications where some axial movement is needed in one direction, while maintaining strong radial load support.
The "E" in the part number signifies an enhanced internal design, typically offering improved load-carrying capacity and durability compared to standard cylindrical roller bearings. The "CP" suffix indicates that the bearing is equipped with a nylon cage. This lightweight and durable cage ensures proper roller spacing, reduces friction, and helps maintain smooth operation, even in high-speed or demanding applications.
The NJ311ECP bearing is commonly used in machinery such as electric motors, gearboxes, pumps, and other industrial equipment where radial load support is required, and limited axial movement is expected. Its design offers reliable, long-lasting performance, making it well-suited for applications that require both flexibility and high radial load-carrying capacity, as well as low maintenance and high operational efficiency.
