Single Row Cylindrical Roller BearingsNU256M Bearing

Single row cylindrical roller bearings are a type of bearing that is designed to support heavy radial loads and high speeds. They are commonly used in industries such as machine tools, paper mills, and electric motors where high precision and reliability are crucial.

These bearings consist of a cylindrical roller and raceway, and are available in a variety of sizes and designs. They can be either integral or separable, and can be designed with different cage materials, such as steel, brass, and polyamide.

One of the main advantages of single row cylindrical roller bearings is their ability to accommodate axial loads in one direction. This makes them particularly useful in applications where axial loads are present and a certain degree of rigidity is required.
