Product features:

Double row design:
Double row tapered roller bearings, designed with two rows of tapered rollers, can simultaneously withstand radial loads and larger axial loads, providing higher load carrying capacity. Compared to single row bearings, double row designs are more suitable for withstanding complex loads and operate more stably.

Enhanced design (X3/X2):
The “X3″ reinforced design of bearings means they have higher load-bearing capacity, longer service life, and stronger impact resistance than conventional bearings, making them particularly suitable for use under heavy loads or complex working conditions. The “X3″ design enables these bearings to maintain excellent performance even under extreme conditions such as high load, high vibration, and poor lubrication.

High temperature adaptability (HCC/HC):
Each bearing is designed with high temperature resistance (HCC) to ensure that it can operate in high temperature environments without failure. High temperatures can cause thermal expansion of bearing materials, increasing friction and wear. HCC design optimizes bearing structure and materials to reduce the negative effects of temperature changes.

Anti pollution design (DF):
Some models (such as 322/530X3/HCC9DF) adopt the “DF” anti pollution design, ensuring that the bearings can still provide reliable working performance when used in harsh environments such as dust, sewage, and oil pollution. This is particularly important for industries such as mining, metallurgy, and construction, as it can effectively extend the service life of bearings and reduce maintenance requirements.

Large clearance design (C3):
The bearing adopts C3 clearance design, which has a large clearance and is suitable for working conditions with large thermal expansion or load fluctuations. At high temperatures, material expansion may cause a decrease in bearing clearance, and the C3 design can effectively compensate for this change, ensuring that the bearing can operate normally and withstand more loads.

Anti vibration and anti impact capability:
The design of double row tapered roller bearings is very suitable for operation in high vibration and high impact environments. By properly configuring the rollers, cage, and outer ring structure, the bearing can effectively resist external impact loads, prevent bearing damage, and maintain the normal operation of the equipment.

Application areas:

Metallurgical industry:
In the metallurgical industry, especially in steel production lines and rolling equipment, double row tapered roller bearings can withstand high loads and high temperatures, ensuring stable operation of equipment under high impact and high temperatures. These bearings are commonly used in equipment such as rolling mills, steel cranes, and furnace material conveying systems.

Mining and Mineral Processing:
In mining machinery, these bearings are widely used in crushers, screening machines, transportation equipment, etc. These devices need to withstand a large amount of impact and vibration loads, so the high load-bearing capacity, vibration resistance, and durability of double row tapered roller bearings are very important.

Construction Machinery:
Double row tapered roller bearings are widely used in construction machinery equipment, such as excavators, bulldozers, cranes and other heavy machinery. They can effectively cope with complex working conditions and high impact loads, ensuring the efficient operation of mechanical equipment.

Wind power generation:
Double row tapered roller bearings are also commonly used in wind turbines. These bearings can withstand irregular loads from wind and, due to their high temperature and impact resistance, can operate stably under extreme weather conditions, ensuring the reliability of wind turbines.
