QIBR self-aligning ball bearings with adapter sleeves have solved many key problems in various fields, which are mainly reflected in the following aspects:

1. Automatic self-aligning function

The biggest feature of QIBR self-aligning ball bearings with adapter sleeves is that they can automatically align. Because the relative position of the raceways of its inner and outer rings has a certain angle (that is, the raceway of the outer ring is spherical). When the shaft or bearing seat is relatively offset, the contact surface of the ball and the raceway will automatically adjust to ensure that the bearing maintains a stable working state and reduce the wear caused by angular error.

2. Load-bearing capacity

QIBR self-aligning ball bearings with adapter sleeves have a relatively strong load-bearing capacity. It can withstand certain radial loads and axial loads.

3. Strong adaptability

QIBR self-aligning ball bearings with adapter sleeves are particularly suitable for occasions where there is an axial deviation during the process of installation due to their self-aligning characteristics. For example, the bending of the shaft, improper installation of the bearing seat, etc., these situations may cause angular deviations in the bearing, but the self-aligning ball bearing can effectively compensate for these problems and keep smooth operation.

4. Connection characteristics

Although the traditional key connection method is simple, it is prone to wear, looseness and damage to the keyway. The adapter sleeve avoids these problems by designing without keys and keyways, thus improving the stability and life of the connection.


The performance improvement and solutions of QIBR self-aligning ball bearing with adapter sleeve 

1. Lubricant optimization: Select appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. The usage of synthetic lubricants or nano-lubricants can significantly improve the efficiency and life of bearings.

2. Raceway optimization: Optimize the raceway geometry of the inner and outer rings, such as increasing the raceway accuracy, improving surface finish, reducing friction, and reducing energy loss, thereby improving the operating efficiency of the bearings.

3. Improve quality of rolling element: Reduce friction and wear by improving the surface finish and hardness of the rolling elements. The usage of high-precision rolling elements (such as ceramics) can significantly improve the running performance of the bearing.

4. Cage design optimization: Adopt a more optimized cage structure, such as using high temperature resistant and corrosion resistant materials and designs, to improve the durability of the cage and the stability of the bearing.


Main application areas of QIBR self-aligning ball bearings with adapter sleeves

Railway vehicle bearings: In railway vehicles, self-aligning ball bearings can cope with problems such as uneven tracks and wheel offset, ensuring the smoothness and reliability of vehicle operation.

Food machinery: For example, equipment such as mixers, packaging machines, conveyor belts, etc., self-aligning ball bearings can adapt to the shaft offset problems caused by vibration and load changes during the operation of the equipment, ensuring stable operation of the equipment.

Wheel bearings: Wheel bearings are often affected by high-speed rotation and irregular loads. Self-aligning ball bearings can better adapt to shaft misalignment or offset problems in wheel systems, reduce wear, and improve performance and durability.

Transmission equipment: In some mechanical transmission systems, self-aligning ball bearings can effectively alleviate problems caused by uneven loads or shaft misalignment.
