Four-Row Cylindrical Roller Bearings
TFL’s Four-Row Cylindrical Roller Bearings are specifically designed to handle the most demanding industrial environments. These robust roller bearings offer an exceptional combination of high radial load capacity, extreme rigidity, and reduced friction. They are the ideal choice for applications subjected to heavy shock loads and continuous operation, ensuring reliability and extended service life for critical machinery.
Optimized Design for Maximum Radial Load
Compared with single or double row cylindrical roller bearings, the four-row version handles much higher radial loads due to its larger number of rolling elements. These bearings are ideal for rolling mill bearings, electric motor bearings, and gearbox bearings where stability and durability are essential.
TFL ensures every bearing meets strict manufacturing standards. The bearing rings and cages are made from high-quality materials and go through strict heat treatment and grinding processes, which guarantees precision performance in harsh environments.
Heavy-Duty Performance in Industrial Applications
Four-row cylindrical roller bearings are widely used in applications such as steel rolling mills, where machines must withstand continuous high radial loads and rapid speeds. The design of these bearings eliminates the need for thrust bearings, reducing space and simplifying the structure.
TFL’s four-row cylindrical bearings provide enhanced load distribution and long-term performance even under extreme working conditions. The precisely machined raceways and optimized roller alignment contribute to lower friction and extended bearing life.

FREQUENTLY ASKED QUESTIONS
What applications are Four-Row Cylindrical Roller Bearings best suited for?
They are ideal for rolling mills and heavy-duty machinery that operate under high radial loads and require high-speed performance.
How important is lubrication for the performance of these industrial bearings?
Bearing lubrication is absolutely critical, particularly for four-row cylindrical roller bearings operating under extreme conditions in rolling mill environments. Proper lubrication is essential to minimize friction, dissipate heat, and prevent premature wear and damage to the cylindrical rollers and bearing rings. Due to the high speeds and heavy loads, these bearings often utilize circulating oil lubrication systems that filter and cool the oil. Neglecting the proper bearing maintenance and lubrication schedule can quickly lead to catastrophic failure, making it a key factor in maximizing the service life and performance of these precision bearings.
How do Four-Row Bearings differ from Single or Double Row Cylindrical Roller Bearings?
The main difference lies in the load capacity. By incorporating four rows of rolling elements, the four-row configuration offers significantly higher radial load support than single or double row cylindrical roller bearings. This makes them suitable for the extreme loads encountered in rolling mill environments. Single-row bearings are typically used for moderate loads and high speed bearings applications, while double-row types offer a balance of load capacity and compactness. The four-row design is the ultimate choice when maximum stiffness and load rating are the primary concerns.
Can these bearings accommodate axial loads effectively?
While Four-Row Cylindrical Roller Bearings are primarily designed to handle very high radial loads, they do not inherently accommodate significant axial load in the same way thrust bearings do. Their design, focused on radial capacity, means that separate arrangements or additional cylindrical roller thrust bearings might be necessary if substantial axial forces are present in the application. However, their high rigidity can contribute to overall machine stability, indirectly benefiting systems with combined radial and lighter axial loads.
