Deep Groove Ball Bearings

1. High load - bearing capacity: The 6220-2RS deep groove ball bearing has a deep groove design on the inner and outer rings, providing a larger contact area to help distribute the load and reduce localized stress concentrations. The balls roll smoothly in the deep grooves, enhancing load-bearing capacity. This ensures the landing gear remains stable during take-off and landing.

2. Low Friction and High Speed: The design of the 6220-2RS deep groove ball bearing features a low friction coefficient, allowing it to maintain excellent performance at high rotational speeds. This is crucial for landing gear systems that require quick response.

Spherical Roller Bearings

1. Self-aligning Capability: The inner ring and outer ring can tilt relative to each other. The spherical shape allows the bearing to adjust itself within a certain angular range, providing excellent self-aligning capability. It can automatically adjust for angular misalignments with the outer ring, ensuring stable operation even in misalignment situations.

2. Wear Resistance: The load is distributed across multiple rollers, reducing the contact stress between each roller and the raceway. Manufactured from high-strength materials and treated with surface hardening, it exhibits excellent tensile strength and toughness, enhancing wear resistance.

Additional Notes:

The customer in Portugal decided to purchase QIBR’s 6220-2RS deep groove ball bearings and 22209 spherical roller bearings to meet the strict durability and stability requirements of aerospace landing gear. Both bearings are made from high-quality materials and undergo rigorous quality control processes to ensure that each product meets the high standards required in the aerospace industry. QIBR uses advanced automated production lines and precision manufacturing technologies to improve production efficiency and reduce costs, ensuring a balanced combination of high performance and cost-effectiveness. These high-quality bearings not only effectively extend service life but also reduce failure rates, enhancing the overall reliability of landing gear systems.
