Libang cylindrical roller bearings are available in several designs:

With a cylindrical or tapered bore
Open or sealed

Four-row cylindrical roller bearings are used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Because they are normally mounted with an interference fit on the roll neck, four-row cylindrical roller bearings are well suited for rolling mill applications where the rolling speed is high.

Because four-row cylindrical roller bearings can accommodate only radial loads, they are mounted together with deep groove or angular contact ball bearings, or with tapered roller bearings (either radial or thrust design) which accommodate the axial loads.

Cylindrical roller bearing are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.

Characteristics:

• Extraordinary Load Capacity: With four rows of cylindrical rollers, these bearings have an extremely high radial load-carrying capacity, making them capable of withstanding very heavy radial forces, which is suitable for applications under heavy loads.
• Good Rigidity and Stability: The four-row structure significantly enhances the bearing's rigidity and stability, reducing deformation and vibration during operation and ensuring the stable operation of the equipment.
• High Rotational Accuracy: They can maintain high rotational accuracy due to the precise arrangement of the rollers and high-quality manufacturing of the raceways, minimizing radial and axial runouts.
• Separable Design: Most four-row cylindrical roller bearings have a separable design. The bearing rings with integral flanges and the roller and cage assemblies can be installed separately from the separable bearing rings, facilitating installation, maintenance and inspection.
• Low Friction: The open flange design, together with the roller end design and surface finish, promotes lubricant film formation, resulting in lower friction and improved efficiency.

Application

• Machine Tools: Widely used in the spindle systems of machine tools, such as lathes, milling machines and grinders. They provide high-precision support for the spindle, ensuring the accuracy and stability of machining operations and helping to improve the quality of machined parts.
• Gearboxes: In various industrial gearboxes, double row cylindrical roller bearings are used to support the rotating shafts of gears. They can bear the radial forces generated by the meshing of gears and ensure the smooth transmission of power, improving the efficiency and service life of the gearbox.
• Automotive Industry: Applied in automotive transmissions and differentials to support the rotating shafts and bear the loads transmitted from the engine and wheels. They play an important role in ensuring the smooth operation of the vehicle and the efficient transmission of power.
• Heavy Machinery: Used in heavy machinery such as cranes, excavators and large-scale presses. These bearings can withstand the huge loads and impact forces in heavy machinery operations, ensuring the reliability and safety of the equipment.
• Rolling Mills2: They are almost exclusively used for the roll necks of rolling mill stands, being able to withstand the huge radial forces generated during the rolling process and high rolling speeds.
• Calenders and Roller Presses: Used in calenders and roller presses to support the rollers and bear heavy radial loads, ensuring the normal operation of the equipment and the quality of the pressed products.
• Heavy Machinery: Applied in other heavy machinery such as large-scale crushers and conveyors. They can bear large loads and impact forces, ensuring the reliable operation of heavy machinery.
