Spherical Roller Bearing

1. Self-aligning Capability: The outer ring of the 22220 spherical roller bearing is spherical in shape, allowing it to self-align within a certain range, accommodating slight misalignments or shaft eccentricity.

2. High Load Capacity: It can withstand large radial loads and certain axial loads, effectively distributing the load to reduce local stress concentration and enhance bearing capacity.

3. Durability: Made of high-strength alloy steel, with heat treatment to improve wear resistance and fatigue resistance, it maintains excellent performance during long-term operation.

Tapered Roller Bearing

1. High Load Capacity: The LM742710 tapered roller bearing can simultaneously handle large radial and axial loads. The load is evenly distributed through the rollers, making it suitable for use in differentials under heavy load and impact conditions.

2. High Reliability: The LM742710 tapered roller bearing undergoes precision machining and strict quality control to ensure long-term reliability, enabling stable operation over extended periods and reducing the likelihood of failures.

Additional Notes:

The U.S. customer decided to purchase QIBR’s 22220 spherical roller bearings and LM742710 tapered roller bearings to meet the high safety and reliability standards required for automotive differentials. Both bearings are made from high-quality materials and combine advanced heat treatment with precision machining processes to ensure durability and stable performance under extreme operating conditions. The 22220 spherical roller bearing's self-aligning feature allows it to effectively adapt to slight misalignments and shaft eccentricity. The LM742710 tapered roller bearing boasts high precision, providing a lower friction coefficient. This reduces energy loss during differential operation, improving overall transmission efficiency and delivering a smoother driving experience.
