BMT Double Row Deep Groove Ball Bearings are manufactured using ISO9001 and IATF16949 certified systems, ensuring rigorous quality control from material selection to final inspection, and are widely used in OEM automotive pumps.
We manufacture and export Double Row Deep Groove Ball Bearings designed for real industrial conditions, not just lab testing. Based on our production experience in Ningbo, China since 2004, we focus on delivering bearings that maintain stable rotation under high radial load, reduced noise, and consistent performance in continuous operation environments.
Our factory operates over 100 sets of automatic grinding and assembly lines, with an annual capacity reaching 100 million pieces. Every batch of Double Row Deep Groove Ball Bearings is traceable from steel selection to final inspection, which is why long-term OEM customers from Europe, Southeast Asia, and South America continue to work with us.
Product Features
1. High load capacity design
The double-row structure increases contact area, making these bearings suitable for higher radial load applications compared with single-row types.
2. Low noise and stable rotation
Precision grinding and strict clearance control help reduce vibration, especially in electric motors and pump systems.
3. Long service life
We use high-quality bearing steel and optimized heat treatment to improve wear resistance under continuous operation.
4. OEM ready production
We support customized dimensions, packaging, and branding for industrial distributors and equipment manufacturers.
5. Verified manufacturing system
Production follows ISO9001 and IATF16949 standards with full inspection records for each shipment.

Real Application Experience
In one of our long-term cooperation cases, a Southeast Asian pump equipment manufacturer replaced their previous supplier due to frequent bearing overheating issues. After switching to our Double Row Deep Groove Ball Bearings, the failure rate dropped significantly during 6 months of field testing under continuous water circulation conditions.
Another European motor repair company reported improved noise control after standardizing our bearings in their refurbished industrial motors, especially in mid-speed operation ranges.
These results are based on real application feedback, not theoretical claims.
Typical Applications
· Electric motors and industrial drives
· Water pumps and irrigation systems
· Automotive auxiliary components
· Textile machinery
· Conveyor and material handling equipment
· Agricultural machinery systems
