Four row cylindrical roller bearings have three basic types: FC, FCD and FCDP type, shown as the follow sketch.

On the three basic types, considering the application and maintenance there are many variants detail structure. The normally featured structure is shown as following sketch:

In bearing table have listed out bearing application data and reference structure sketch number for the bearings in common lese, also have listed out some reference designation of the most famous bearing company, so to make it easy for you to select.

DHK can produce other special bearings according to customer request.
DHK four row cylindrical roller bearings are produced either solid brass cages or pin-type steel cages.

DHK four row cylindrical roller bearings are produced to the normal tolerance class (PN) or closer tolerance class such as P6 or P5 upon request.

Detailed tolerance values are listed in tolerance of radial bearings. Page 8.

1. Introduction to Series FCD-Four Row Cylindrical Roller Bearings

The evolution of Series FCD bearings stems from a comprehensive understanding of the challenges encountered in industries such as steel manufacturing, mining, and pulp and paper production, where machinery operates under extreme conditions of pressure, temperature, and load. At their core, Series FCD bearings boast a construction engineered to withstand the most punishing operating conditions. The hallmark of these bearings is their arrangement of four rows of cylindrical rollers, meticulously crafted to distribute radial loads with unparalleled uniformity. This innovative design not only enhances load-carrying capacity but also minimizes stress concentrations, thereby extending the operational lifespan of the bearing. The outer raceway, meticulously machined to exacting tolerances, provides a robust housing for the rollers, safeguarding against deformation and wear under heavy loads, ensuring optimal alignment and smooth operation under dynamic loads. This meticulous craftsmanship translates into reduced friction, minimized power loss, and enhanced overall efficiency in heavy machinery applications.

2. Functionality and Performance

Series FCD bearings exhibit remarkable axial load-carrying capacity, making them well-suited for applications involving heavy axial loads or combined radial and axial loads. Whether subjected to high-speed rotation, oscillating motion, or intermittent shock loads, these bearings maintain their integrity and performance, providing reliable support and stability to critical machinery components.This capability is particularly advantageous in applications where combined radial and axial loads are prevalent, such as in gearboxes, extruders, and paper-making machinery. The ability to support heavy axial loads ensures optimal performance and reliability, even in the most demanding operating conditions, thereby instilling confidence in the longevity and efficiency of industrial processes. The multi-row configuration, coupled with precision-ground surfaces, facilitates smooth and efficient operation, minimizing frictional losses and maximizing energy efficiency. This inherent design enables Series FCD bearings to excel in applications characterized by high radial loads, such as rolling mills, crushers, and heavy machinery, where the ability to withstand extreme forces is paramount.
