Self-aligning ball bearings with an extended inner ring

Self-aligning ball bearings with an extended inner ring are a type of rolling bearing designed to accommodate angular misalignment between the shaft and housing while maintaining smooth operation.

Design in two rows of balls running on a common spherical raceway in the outer ring; Pivoting inner ring that can compensate for misalignments and shaft deflections; Extended inner ring for easy installation and axial fixation using a tenon screw

QIBR self-aligning ball bearings with extended inner rings 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 extended inner rings is that they can automatically align. Because the relative position of the raceways of the 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 keeps stable working state and reduce the wear caused by angle errors.

2. Carrying capacity

QIBR self-aligning ball bearings with extended inner rings have relatively strong carrying capacity. It can withstand certain radial loads and axial loads.

3. Strong adaptability

QIBR self-aligning ball bearings with extended inner rings are particularly suitable for occasions where there is axial offset 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 deviation of the bearing, but the self-aligning ball bearing can effectively compensate for these problems and maintain smooth operation.

4. Structural features

QIBR self-aligning ball bearings with extended inner rings are double-row designs with two-row ball cages, which can withstand large radial loads.

The performance improvement and solutions of QIBR self-aligning ball bearings with extended inner ring

1. Lubricant optimization: Choose 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 bearing.

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. The optimization of cage design: 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.
