Your Professional Single Row Cylindrical Roller Bearing Supplier
Single row cylindrical roller bearings have a unique roller and raceway design. They have excellent load carrying capacity and stability, making them very suitable for automotive wheel hub bearings. Compared with other bearings, the rollers and raceways of cylindrical roller bearings are in line contact and have a larger contact area, which can effectively disperse the load and improve the load capacity of the bearing. This design can effectively improve the stability of the wheel bearing, thereby improving the safety and stability of the car when driving at high speeds.
DUHUI is a Chinese automotive bearing manufacturer with over 20 years of experience in the R&D and manufacturing of single row cylindrical roller bearings. We have ISO9001 and TS16949 professional certifications. Our factory covers an area of 10,000 square meters and has 4 fully automatic production lines, which can steadily supply 100,000 sets of high-quality bearings per month. We have been focusing on automotive bearings for 20 years, and our technical team has improved single row cylindrical roller bearings based on the application requirements of automotive wheel bearings. From material selection to manufacturing process and quality inspection, we always adhere to high standards to ensure that our bearings can meet and exceed OE standards.
DUHUI has established strict production and quality inspection standards to ensure the quality of our bearings. From material selection to process, every step is carried out with high standards. We select premium high-carbon core bearing steel as raw material to ensure the wear resistance and fatigue resistance of the bearings. Our processing accuracy reaches micron level. In the bearing manufacturing process, from forging, heat treatment to super finishing, the tolerances and other standards for each step are set by our technical experts through repeated testing. We have also established a complete full-process quality control system and laboratory testing system to ensure ensure consistent bearing quality.

High-Precision Standards for DUHUI Single Row Cylindrical Roller Bearings
DUHUI has purchased advanced CNC machine tools, and our bearing grade can reach P6 and above. The raceways of our single row cylindrical roller bearings are finely and super-finished, with a surface roughness of up to 0.1 μm. The maximum symmetry deviation of our single-row cylindrical roller bearings is controlled to around 1 μm.


Full-Process Quality Control System for DUHUI Single Row Cylindrical Roller Bearings
From basic turning, grinding, finishing and super finishing of single row cylindrical roller bearings, we have equipped each process with standard testing equipment to monitor the bearing parameter standards. All our processing parameters are strictly in accordance with the national GB/T standards and original equipment manufacturer (OE) standards. Once there is a workpiece that does not meet the standards, it will be immediately reworked or scrapped.
Laboratory Testing System for DUHUI Single Row Cylindrical Roller Bearings
In addition to basic testing during the manufacturing process, we have established a comprehensive laboratory testing system. We have purchased various testing instruments, including length gauges, roundness gauges, roughness gauges, and hardness testers. Before packaging, our bearings undergo various tests by a dedicated quality inspection team to ensure that they meet quality standards.

Our bearing MOQ is 50 pieces. If you require custom packaging, the MOQ may be higher. Because the MOQ of customized packaging is higher.
We mainly produce single row cylindrical roller bearings that meet OE standards, which are widely used in the automotive aftermarket. However, we can accept custom non-standard bearings, and we also have the ability to customize standard bearings.
For single row cylindrical roller bearings, we usually use individual packing boxes. Each bearing is wrapped in a plastic bag and then placed in a box. Note: We typically use neutral boxes or DUHUI branded color boxes.
