Your Professional Double Row Angular Contact Ball Bearing Manufacturer
A double row angular contact ball bearing has double rows of bearing balls, which is the biggest difference between it and a single row angular contact ball bearing. While maintaining the advantages of the angular contact ball structure, it has a stronger load capacity and stability, and is widely used in automotive wheel bearings. The integrated design makes installation and maintenance very convenient. And double row angular contact ball bearings save more space and are more suitable for automotive bearings.
DUHUI is an automotive bearing manufacturer in China. Double row angular contact ball bearings are one of our key products. We have 20 years of experience in R&D and manufacturing of double row angular contact ball bearings. Our double row angular contact ball bearings are improved for automotive wheel bearings. DUHUI double row angular contact ball bearings adopt a double row ball design and optimized force design. The double row balls can evenly distribute the load, improve the load-bearing capacity and stability, and effectively extend the bearing life.
DUHUI uses high-quality GCR15 bearing steel as raw material. We require raw material suppliers to provide CNAS material testing reports to ensure that the carbon and chromium content of the bearing steel meet the standards. After completing the forging of the bearing blank, we need to normalize the bearing blank before formal turning. High temperature normalizing for 4 hours to improve the toughness and fatigue strength of the bearing. And we will perform targeted quenching treatment to further improve the hardness, wear resistance and fatigue strength of the bearings.
DUHUI can provide you with more than 2,000 types of double row angular contact ball bearings, covering most models in the aftermarket. Our bearings meet OE standards, and are replaced in the aftermarket. Request a free sample from us.

Strict Material Standards for DUHUI Double-Row Angular Contact Ball Bearings
DUHUI double row angular contact ball bearings are mainly manufactured from GCR15 bearing steel. We have very strict requirements for the selection of GCR15 bearing steel. Raw material suppliers need to provide CNAGB/T 18254S material test reports to ensure that GCR15 bearing steel meets the GB/T 18254 standard. This test not only needs to analyze the content of carbon, chromium and other elements in the steel, but also needs to analyze the internal structure of the steel.
Strict Manufacturing Standards of DUHUI Double Row Angular Contact Ball Bearings
DUHUI double row angular contact ball bearings’ strict manufacturing standards ensure their excellent quality. To ensure bearing quality, our technical experts have established a series of precision standards. For example, we perform fine machining and super-finishing on bearing raceways to ensure that the surface roughness is controlled within 0.1 micron.
Strict Testing Standards for DUHUI Double-Row Angular Contact Ball Bearings
DUHUI double row angular contact ball bearings need to undergo multiple strict tests before shipping. One of the tests is the salt spray test for corrosion resistance. We require a simulated salt spray environment, with the temperature controlled at around 35°C and 5% sodium chloride solution continuously sprayed. We require that the bearings run normally for 720 hours without rust.
DUHUI double row angular contact ball bearings have an integrated structure, are smaller and more space-saving. Its double row structure has greater load capacity and stability.
Double-row angular contact ball bearings are more suitable for high-load situations.
Single-row bearings are more suitable for low-load, high-speed situations.
During the bearing manufacturing process, DUHUI has improved the process to meet the hardness, toughness, wear resistance, and impact resistance requirements of automotive wheel bearings.
