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. Structural Overview and Design Principles

Series FC-Four Row Cylindrical Roller Bearings boast a sophisticated design meticulously crafted to meet the demands of heavy-duty industrial applications. At the core of their structure lies a configuration comprising four separate rows of cylindrical rollers, arranged in a symmetrical pattern. This design ensures optimal load distribution across the bearing, effectively mitigating stress concentrations and minimizing the risk of premature failure. Each row of cylindrical rollers operates independently, yet collectively they work in tandem to support radial loads with exceptional efficiency. This inherent redundancy not only enhances load-carrying capacity but also improves the bearing's ability to withstand dynamic forces, such as shock and vibration, commonly encountered in industrial environments. Integral flanges integrated into the inner and outer rings serve multiple functions, including guiding and retaining the rollers within their respective races. By preventing axial displacement of the rollers, these flanges contribute to the bearing's axial load-carrying capability, enabling it to support moderate thrust loads while maintaining stability and precision in operation. The internal geometry of Series FC bearings undergoes rigorous optimization to maximize contact area between rollers and raceways. This meticulous engineering minimizes stress concentrations and edge loading, factors known to compromise bearing performance and longevity. The result is a bearing with enhanced load distribution characteristics, reduced frictional losses, and improved resistance to wear and fatigue.

2. Performance Advantages and Benefits of Series FC-Four Row Cylindrical Roller Bearings

The utilization of Series FC-Four Row Cylindrical Roller Bearings offers a myriad of performance advantages, underscoring their significance in modern industrial machinery:

a)High Radial Load Capacity: The four-row design of Series FC bearings facilitates uniform load distribution, enabling them to withstand heavy radial loads with remarkable efficiency. This characteristic is particularly beneficial in applications where equipment operates under extreme loads and stresses.

b)Excellent Axial Load Resistance: The incorporation of integral flanges and optimized internal geometries enhances the bearing's ability to withstand axial loads, ensuring stability and reliability in operation. This feature is instrumental in applications where axial forces are present, such as in gear drives and thrust-bearing arrangements.

c)Reduced Maintenance Requirements: Series FC bearings are engineered for durability and longevity, minimizing the need for frequent maintenance interventions. This translates to increased uptime, reduced downtime-related costs, and enhanced overall productivity for industrial operators.

d)Enhanced Operational Longevity: By leveraging premium materials and advanced manufacturing techniques, Series FC bearings exhibit superior resistance to wear, fatigue, and surface damage. This extended service life not only reduces replacement frequency but also contributes to lower total cost of ownership over the bearing's lifecycle.
