Single Row Cylindrical Roller BearingsNF1021M 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.


Single Row Cylindrical Roller Bearings are high precision bearings designed for heavy radial loads and low friction performance. NF1021M is a versatile series of bearings that are ideal for use in a wide range of applications, from machine tools to power generation equipment.

These bearings feature a cylindrical shape that allows for superior contact with the outer raceway and optimum load distribution, resulting in long-lasting and reliable performance. The single row design also enables easy installation and minimal maintenance, making these bearings an excellent choice for many industrial and commercial settings.

NF1021M bearings are constructed with high-quality materials and precision manufacturing processes, ensuring exceptional durability, performance, and low noise levels. The bearings are designed to operate at high speeds, with optimal tolerances, and can withstand extreme temperatures and harsh environments.

These single-row cylindrical roller bearings are easy to install and maintain and come in a variety of sizes and designs to meet the needs of your specific application. They are compatible with a range of lubricants and can handle high loads and speeds with low friction.
