Your Reliable Double Row Cylindrical Roller Bearing Supplier
Double row cylindrical roller bearings improve the double-row roller structure design based on the structural design advantages of single row cylindrical roller bearings. Compared with single row bearings, its load capacity, impact resistance, precision and stability have been greatly improved. Double row cylindrical roller bearings can effectively cope with various complex situations encountered by cars during high-speed driving.
Since its establishment in 2003, DUHUI has been focusing on the automotive bearing industry, providing automakers with safe and reliable wheel bearings – double row cylindrical roller bearing solutions. Our factory has both ISO9001 and TS16949 certifications, with a monthly output of 100,000 sets of double row cylindrical roller bearings. We have a complete cylindrical roller bearing library. We currently have over 2,400 types of cylindrical roller bearings, which can cover most car models in the aftermarket. And we can support your customized needs of “small batch, multiple varieties”. In the automotive bearing aftermarket, DUHUI bearings are well-known for their quality and service.
To improve the quality of double row cylindrical roller bearings, DUHUI has established strict production system standards. Our production standards strictly follow the IATF 16949 system. Starting with raw material selection, our bearing steel is sourced from premium suppliers like Baosteel, and each batch of raw materials passes material testing. During the entire production process, we strictly control the requirements of each step. For example, the surface roughness of the bearing raceway must be controlled within 0.1 microns after super finishing. All our bearings are 100% batch inspected before shipment.
With over 20 years of manufacturing experience and over 15 years of foreign trade experience, DUHUI can provide better quality and service. Our sales team is very reliable, so if you have any questions, please feel free to contact us. Get a quote for double-row cylindrical roller bearings now.

Roller Improvement of DUHUI Double Row Cylindrical Roller Bearings
DUHUI technical experts have improved the rollers of double row cylindrical roller bearings based on the application of automotive wheel bearings. Specially treated rollers can greatly improve the load capacity and stability of the bearing. Compared to single-row bearings, the load capacity of double row cylindrical roller bearings is increased by more than 30%, and can effectively withstand the load and impact during car high-speed driving. And after testing, it has been found that it can maintain good stability even under long-term high-speed operation.
Friction Improvement of DUHUI Double Row Cylindrical Roller Bearings
DUHUI has purchased advanced CNC super-finishing machine tools. Our bearing raceways are fine-machined and super-finished, and the surface roughness can be controlled within 0.1 micron. Our roller surfaces are also specially treated. And we also use high-quality, low-friction grease. After testing, the temperature rise of our bearings is controlled within 15°C during long-term high-speed operation, which effectively increases the bearing.
Sealing Improvement of DUHUI Double Row Cylindrical Roller Bearings
DUHUI double row cylindrical roller bearings use a double composite seal structure, which can not only effectively prevent the leakage of lubricating grease, but also effectively block the invasion of external pollutants. This design can effectively extend the bearing life and make it maintenance-free during its life.
