China Bearing Manufacturer Four Row Cylindrical Roller Bearing 4R3821/4R3817/4R3823

1. Product Overview

Our Four Row Cylindrical Roller Bearings 4R3821/4R3817/4R3823 are meticulously crafted by a leading China bearing manufacturer. These bearings are designed to handle high radial loads with exceptional precision and efficiency. They are an ideal choice for various industrial applications where heavy radial forces are present, such as in rolling mills, construction machinery, and mining equipment.

2. Material and Durability

The bearings are made from high - quality bearing steel. This material offers excellent hardness, wear resistance, and fatigue strength. The use of bearing steel ensures that the bearings can withstand the harsh operating conditions and heavy loads without significant deformation or premature failure. It also provides good corrosion resistance, which is crucial for applications in environments where moisture or chemicals may be present.

3. Design and Structure

Row Configuration

As four - row cylindrical roller bearings, they feature four rows of cylindrical rollers. This multi - row design allows them to distribute the radial load evenly across the bearing, reducing stress concentrations and increasing the overall load - carrying capacity. Compared to single - row or double - row bearings, four - row cylindrical roller bearings can handle much higher radial loads, making them suitable for heavy - duty applications.

Roller Design

The cylindrical rollers are precisely engineered to provide smooth rolling motion. Their shape and dimensions are carefully calculated to ensure optimal contact with the raceways, minimizing friction and heat generation. This not only improves the efficiency of the bearing but also extends its service life.

4. Performance Advantages

High Radial Load Capacity

One of the key advantages of these bearings is their ability to handle extremely high radial loads. The four - row design and the use of high - quality materials enable them to support heavy machinery and equipment, ensuring stable operation even under the most demanding conditions.

Low Friction

The smooth rolling motion of the cylindrical rollers results in low friction. This reduces energy consumption and heat generation, which is beneficial for both the environment and the overall performance of the equipment. Lower friction also means less wear on the bearing components, leading to longer maintenance intervals and lower operating costs.

Precision and Accuracy

Our manufacturing process adheres to strict quality control standards, ensuring high precision and accuracy in the dimensions and performance of the bearings. This precision is essential for applications where accurate positioning and smooth operation are required, such as in machine tools and robotics.

5. Application Fields

Industrial Machinery

In rolling mills, these bearings are used to support the rolls, which are subjected to high radial forces during the rolling process. Their high load - carrying capacity and precision ensure the efficient operation of the mill and the quality of the rolled products.

Construction and Mining

In construction machinery and mining equipment, such as excavators and crushers, the bearings are used to support various moving parts. The ability to withstand heavy loads and harsh environments makes them a reliable choice for these applications.

Other Industries

They can also be used in other industries where high - radial - load handling is required, such as in power generation, transportation, and manufacturing.

6. Quality Assurance

We are committed to providing high - quality products. Our bearings undergo a series of strict quality inspections during the manufacturing process, including material testing, dimensional measurement, and performance testing. Only products that meet our high - quality standards are allowed to leave the factory. This ensures that our customers receive reliable and long - lasting bearings for their applications.

7. Compatibility

The 4R3821/4R3817/4R3823 bearings are designed to be compatible with a wide range of equipment. They can be easily integrated into existing systems, replacing worn - out or damaged bearings without the need for major modifications. Our technical support team can also provide assistance in the selection and installation of the bearings to ensure optimal performance.

In conclusion, our Four Row Cylindrical Roller Bearings 4R3821/4R3817/4R3823 are a reliable and high - performance solution for various industrial applications. With their excellent material, design, and performance advantages, they offer long - term value and peace of mind to our customers.
