Four Row 4R3639 Rolling Mill Bearing: A Premium Cylindrical Roller Bearing

Product Overview

Our Four Row 4R3639 Rolling Mill Bearing is a high - performance cylindrical roller bearing designed to meet the demanding requirements of rolling mill applications. With dimensions of 180280180mm, this bearing is engineered to provide exceptional reliability and durability in challenging industrial environments.

Material Excellence

This bearing is crafted from bearing steel, a material renowned for its outstanding mechanical properties. Bearing steel offers high hardness, excellent wear resistance, and good toughness. These characteristics ensure that the bearing can withstand heavy loads, high - speed rotations, and the harsh conditions typically encountered in rolling mills. The use of bearing steel also contributes to a longer service life, reducing the frequency of replacements and minimizing downtime for maintenance.

Design and Structure

Four - Row Configuration

As a four - row cylindrical roller bearing, it has a unique design that allows it to handle extremely high radial loads. The multiple rows of rollers distribute the load evenly across the bearing, enhancing its load - carrying capacity. This is crucial in rolling mill operations where large forces are exerted on the bearings during the rolling process.

Cylindrical Roller Design

The roller bearings within the 4R3639 are cylindrical in shape. Cylindrical rollers have a larger contact area with the raceways compared to other types of rolling elements, such as balls. This larger contact area results in lower contact stress, which in turn improves the bearing's ability to handle heavy radial loads. Additionally, the cylindrical shape allows for smooth and efficient rolling motion, reducing friction and energy consumption.

Performance Advantages

High - Speed Capability

The 4R3639 bearing is designed to operate at high speeds. Its precise manufacturing and high - quality materials ensure stable performance even under high - speed conditions. This is essential for modern rolling mills, which often require high - speed operations to increase production efficiency.

Low Friction

The smooth rolling motion of the cylindrical rollers and the high - quality surface finish of the raceways contribute to low friction within the bearing. Reduced friction not only saves energy but also generates less heat, which helps to extend the bearing's service life and improve its overall performance.

Excellent Rigidity

The bearing provides excellent rigidity, which is vital for maintaining the accuracy of the rolling mill. Rigidity ensures that the bearing can resist deformation under load, allowing for precise control of the rolling process and the production of high - quality rolled products.

Application Scope

This bearing is specifically designed for use in rolling mills, but its high - performance characteristics make it suitable for other heavy - duty applications as well. It can be used in various industries, such as steel production, aluminum rolling, and other metal - processing industries. In these applications, the 4R3639 bearing plays a crucial role in ensuring the smooth and efficient operation of the equipment.
