As the world moves toward electrification, digitalisation, and sustainability, electric motor manufacturers face increasing demands for performance, efficiency and reliability. Whether it’s powering industrial drives, HVAC systems, household appliances or electric vehicles, motors today are expected to operate longer, faster, and more quietly, often under tighter space constraints and cost pressure.
Amidst these evolving demands, bearing selection plays a crucial role in both the performance and longevity of electric motors. For many manufacturers, double row ball bearings, especially those designed and manufactured by Neuweg, offer a smart, future-ready solution.
Key Challenges Facing Electric Motor Manufacturers
- Miniaturisation with Power Density – Motors must deliver more torque and speed in smaller frames, increasing stress on internal components like bearings.
- Efficiency and Low Energy Loss – Regulatory and environmental standards demand reduced friction and higher mechanical efficiency.
- Noise and Vibration Reduction – From consumer appliances to EVs, quieter operation is now a critical quality factor.
- Extended Service Life – End-users expect longer maintenance cycles, particularly in HVAC, EV, and industrial applications.
- High-Speed and High-Load Performance – Modern motors often operate at high RPMs and must manage complex axial and radial load combinations.
The Role of Double Row Ball Bearings
Double row bearings provide an ideal solution to these challenges. Their design allows for:
Higher Load Capacity in a Compact Design
Two rows of balls enable higher radial and axial load handling within a smaller footprint – perfect for compact motor designs.
Improved Axial Rigidity
Especially in angular contact configurations, double row bearings stabilize the shaft under axial thrust, improving motor precision and reducing vibration.
Reduced Maintenance Needs
Sealed versions protect from contaminants, reducing the need for relubrication and extending service life.
Versatility Across Applications
From HVAC and home appliances to robotics and EVs, double row bearings support a wide variety of motor types and performance levels.
Choosing the Right Bearing for Each Motor
1. HVAC Motors (Fans, Blowers, Compressors)
Recommended Bearing Type: Double Row Deep Groove Ball Bearings
Why:
- Efficient handling of radial loads with occasional axial load.
- Quiet operation, low friction – ideal for HVAC applications.
- Sealed versions prevent dust and moisture ingress (important for air systems).
2. Industrial Motors (Pumps, Conveyor Drives, Compressors)
Recommended Bearing Type: Double Row Angular Contact Ball Bearings or Matched Duplex Bearings
Why:
- Handles combined radial + axial loads from belts, shafts, and fluid resistance.
- High rigidity and load stability enhance shaft alignment.
- Durable under variable load conditions and harsh environments.
3. Electric Vehicle (EV) Motors & Traction Motors
Recommended Bearing Type: Double Row Angular Contact Ball Bearings (often with ceramic balls or low-friction seals)
Why:
- High-speed operation with precise control of shaft movement.
- Handles strong axial forces during acceleration/deceleration.
- Ceramic hybrids reduce heat and extend lifespan at high RPMs.
4. Robotics, CNC Spindles, and Servo Motors
Recommended Bearing Type: Duplex Angular Contact Ball Bearings (Back-to-Back Configuration) and Double Row Angular Contact Bearings with preload
Why:
- Superior axial stiffness and positioning accuracy.
- Preload options eliminate backlash, vital for precision.
- High rigidity supports frequent direction changes and fine control.
5. Home Appliances (Washing Machines, Dishwashers, etc.)
Recommended Bearing Type: Double Row Deep Groove Ball Bearings (sealed/shielded)
Why:
- Cost-effective and reliable.
- Withstands radial and minor axial loads from drum and motor movement.
- Sealed designs protect from moisture and detergent exposure.
