The NN3020 is a double row cylindrical roller bearing designed for high radial load capacity and rigidity. Key features include a compact design, high precision manufacturing, and the ability to accommodate moderate axial loads in both directions. These bearings typically utilize high-quality steel for the rings and rollers, ensuring durability and long service life.

The primary advantages of the NN3020 lie in its high load-carrying capacity, which allows it to withstand significant radial forces in demanding applications. Its rigidity minimizes deflection under load, ensuring accurate positioning and maintaining tight tolerances. Furthermore, the double row configuration provides increased stability and reduces the risk of misalignment.

NN3020 bearings find widespread application in various industries, including:

Machine Tools: Used in spindles, feed drives, and other components where high precision and rigidity are crucial, such as in milling machines, lathes, and grinding machines.

Automotive: Employed in transmissions, differentials, and other drivetrain components that experience high loads and rotational speeds.

Industrial Machinery: Utilized in pumps, compressors, conveyors, and other heavy-duty equipment requiring reliable and durable bearings.

Aerospace: Incorporated into aircraft engines, landing gear, and other critical components where weight and performance are paramount.
