Double Row Angular Contact Ball Bearings

With more than 20 years of bearing manufacturing experience, BMT Bearings produces Double Row Angular Contact Ball Bearings in ISO9001 and IATF16949 certified facilities.

These bearings are engineered for equipment that operates under:

Continuous high-speed rotation

Combined radial and axial loading

Limited installation space

Long maintenance intervals

Each production batch follows controlled manufacturing procedures, including precision machining, heat treatment, grinding, assembly, and final inspection.

Before shipment, every bearing is tested for dimensional accuracy, running noise, vibration level, and rotational stability to ensure consistent performance in industrial use.

Technical Parameters

Key Engineering Features

1. Combined Load Capacity

Designed to support radial load + axial load in both directions, reducing the need for additional bearing assemblies.

2. High Structural Rigidity

Double-row design increases stiffness, improving shaft alignment stability under heavy load conditions.

3. Low Vibration Operation

Precision-grade steel balls and raceway finishing reduce noise and vibration during high-speed operation.

4. Improved Service Life

Optimized internal geometry reduces friction and heat generation, extending operational life in continuous-duty systems.

5. Space-Saving Design

Combines two angular contact bearings into one unit, reducing installation space and simplifying housing design.

Manufacturing & Quality Control

Production is carried out using standardized industrial processes:

• Certified bearing steel selection
• CNC grinding and ultra-precision finishing
• Automatic assembly systems
• Clearance and preload control testing
• Noise and vibration inspection
• High-speed performance simulation testing

The factory operates multiple automated production lines to ensure dimensional consistency across large-volume orders.

Application Areas

This bearing type is commonly used in:

• Industrial electric motors
• Automotive transmission systems
• Pumps and compressors
• Agricultural machinery
• Construction and heavy equipment
• Gearboxes and industrial drives

In these applications, the main performance requirements are stability, durability, and reduced downtime, especially under continuous load conditions.
