Tapered Roller Bearings

1. High load Capacity: The NA691 - 672D tapered roller bearings feature a tapered inner and outer ring raceway design, where the rolling elements meet at the centerline of the bearing, allowing them to bear significant radial and axial loads. This makes them suitable for automotive drive shafts that operate under high load conditions, transferring substantial torque and power. 

2. Impact Resistance:  The NA691 - 672D tapered roller bearings are designed with a large contact area between the rollers and the inner and outer rings, offering strong durability when subjected to vibration and shock loads. This ensures they can withstand the dynamic conditions in automotive drive shafts during operation.

Deep Groove Ball Bearings

1. Smooth Operation: The 6012 deep groove ball bearings excel in high-speed rotation, reducing friction and maintaining low vibration and noise levels during operation. This results in enhanced vehicle efficiency and a smoother driving experience.

2. High-speed Performance: These bearings are ideal for high-speed rotations, maintaining excellent performance even at high rotational speeds due to their low friction characteristics. This improves the stability of the automotive drive shaft during operation.

3.Stability and Reliability: The 6012 deep groove ball bearing is precisely processed, possessing good rotational accuracy and stability. Under proper use and maintenance, it can maintain a good working condition for a long time and reduce the failure rate.

Additional Notes:

The Canadian customer selected NA691 - 672D tapered roller bearings and 6012 deep groove ball bearings from QIBR to improve the load capacity and stability of their automotive drive shaft. The NA691 - 672D tapered roller bearings are designed to handle large radial and axial loads, with roller arrangements that effectively distribute the load and reduce friction, increasing the drive shaft's load capacity and stability, ensuring smooth operation even at high speeds. The 6012 deep groove ball bearings, manufactured with high-precision steel and advanced manufacturing processes, can bear significant radial loads and some axial loads. They are ideal for high-speed components in automotive drive trains, minimizing the impact of bearing wear and ensuring low noise, low friction, and high efficiency.

These bearings provide a reliable solution for improving the drive shaft's performance, reducing maintenance and enhancing overall vehicle stability and durability.
