Product features:

Double row design:

Double row vertebral column roller bearings consist of two rows of tapered rollers, providing higher load-bearing capacity. Compared to single row roller bearings, double row designs can distribute loads more evenly, reduce friction during operation, and extend the service life of bearings. It can withstand both radial and large axial loads simultaneously, making it suitable for high load working environments.

Enhanced design (X3/X2):

X3 “indicates that this bearing has stronger durability and load-bearing capacity, suitable for working in harsh working conditions. X2 “represents a relatively moderate reinforcement design, suitable for applications with high load requirements but without extreme working conditions. The enhanced design ensures that the bearings can still operate stably in high load, vibration, or high temperature environments.

High load-bearing capacity and stability:

This series of double row vertebral column roller bearings has extremely high load-bearing capacity and can withstand a wide range of radial and axial loads. This makes it particularly suitable for industrial equipment to withstand large impact loads, frequent starting and stopping conditions.

High temperature adaptability:

The “HCC” and “HC” markings in the bearing indicate that it has strong high-temperature resistance and can operate in high-temperature working environments, ensuring that the bearing will not experience performance degradation or damage due to high temperatures.

Large internal clearance (C3):

The bearing adopts a C3 clearance design, which has a large clearance and can adapt to thermal expansion in high-temperature working environments. This design helps to reduce friction at high temperatures, improve bearing stability and longevity, especially suitable for high temperature and high load conditions.

Vibration and impact resistance:

The design of double row rollers can more effectively resist the impact and vibration loads during bearing operation. This design allows the bearings to maintain high stability even when the equipment is subjected to large vibrations or impacts.

Application areas:

Metallurgical industry:

Double row tapered roller bearings are widely used in steel mills, metallurgical equipment, especially heavy machinery such as rolling mills and steel cranes. Its high load-bearing capacity and high temperature resistance are very suitable for heavy load and high temperature environments in the metallurgical industry.

Mining machinery:

Double row column roller bearings are widely used in mining machinery, such as crushers, screening machines, mining transportation equipment, etc. It can withstand strong impact loads and operate efficiently under high temperature and harsh conditions.

Construction Machinery:

In construction machinery such as cranes, excavators, bulldozers, etc., double row column roller bearings are often used in heavy load and high impact working environments due to their high load-bearing capacity and anti vibration performance.

Wind power generation:

Double row tapered roller bearings are used in wind turbines to ensure their stability and reliability in wind environments. Especially in the spindle and gearbox, bearings can withstand irregular loads from wind.

Railway transportation and heavy trucks:

In fields such as railway transportation and heavy trucks, bearings can withstand enormous loads and repeated impacts, ensuring the normal operation of transport vehicles.

Technical parameters:

Size specifications:

The dimensions of each type of bearing (inner diameter, outer diameter, width, etc.) can be customized or selected according to customer requirements. Usually, the larger the bearing size, the greater its load-bearing capacity.

Gap:

This series of bearings adopts C3 clearance design and is suitable for extreme working conditions such as high temperature, high speed, and high load. A larger clearance can prevent thermal expansion caused by temperature rise, thereby improving the stability and service life of the bearing.

Accuracy level:

This series of bearings usually offers P5 or higher precision levels, ensuring that the bearings can maintain high precision during high-speed operation and adapt to harsh working requirements.

Material Science:

Use high-quality alloy steel or high-temperature resistant alloy materials to ensure that bearings can maintain excellent performance in high load, high temperature, and high impact environments.

Summary:

Double row vertebral column roller bearings (models: 372292X3HC3, 370696X3/HC, 370696X2HC) are high-performance bearings designed for high load, high temperature, and high impact environments. They have high load-bearing capacity, high temperature resistance, vibration resistance, and long service life, and are suitable for various industries such as metallurgy, mining, wind power generation, and construction machinery.
