Deep Groove Ball Bearing

1. Large Contact Area: The contact area between the balls and the inner and outer rings is relatively large, effectively distributing loads and allowing the bearing to withstand greater radial and axial loads, making it suitable for high-speed rotation conditions.

2. Low Friction and High Efficiency: The optimized design of the bearing features deep grooves that allow the steel balls to roll smoothly between the rings. This results in a low coefficient of friction, reducing friction and vibration during operation and minimizing energy loss.

3. Good Operational Stability: The 4213 ATN9 deep groove ball bearing maintains stability during operation, reducing vibration and noise.

Tapered Roller Bearing

1. High Stiffness and Load Capacity: The 32928 tapered roller bearing can handle large radial and axial loads simultaneously, providing stable operation under complex conditions and impact loads, making it suitable for ship propeller systems.

2. Impact Resistance: The geometry of the 32928 tapered roller bearing allows it to withstand both radial and axial loads. When subjected to impacts or transient loads, it evenly distributes stress, reducing local stress concentration and adapting to severe fluctuations and impacts encountered by ships during navigation.

Additional Notes:

The Spanish customer decided to purchase QIBR's 4213 ATN9 deep groove ball bearings and 32928 tapered roller bearings to meet strict standards for safety and impact resistance in ship propellers. QIBR's 4213 ATN9 deep groove ball bearing features a low coefficient of friction that helps improve the overall operational efficiency of the ship's propeller system; lower friction reduces energy loss, enhances fuel economy, and lowers operating costs. After using QIBR's 4213 ATN9 deep groove ball bearings and 32928 tapered roller bearings, maintenance frequency decreases, downtime is reduced, leading to improved overall production efficiency and economic benefits for the ships.
