Four row cylindrical roller bearing

A cylindrical roller with four rows of parallel distribution, featuring cylindrical and conical inner holes. Due to the arrangement of more rolling elements, it has extremely high radial load capacity and is highly suitable for high-speed rolling mill industry applications.

Characteristics and advantages

High load-bearing capacity

Due to the large number of rollers, four column cylindrical roller bearings are suitable for very heavy radial loads.

Long service life

Improve operational reliability

The surface treatment of the contact surface between the roller and the raceway is beneficial for the formation of a hydrodynamic lubricating oil film.

Separable and interchangeable

The separation components of the four column cylindrical roller bearings are interchangeable, making them easy to install, disassemble, and maintain for inspection.

High speed capability

The cage design is suitable for high speeds, rapid acceleration, and high loads.

Low cross-sectional height

The low cross-sectional height of four column cylindrical roller bearings allows for the use of roller neck diameters that are larger than the roller diameter.

Application area 

Gearboxes, motors, wind turbines, engineering machinery equipment, pumps and compressors, material conveying equipment, textile machinery, rail vehicles, metallurgical equipment, machine tool spindles, etc.
