Characteristics and advantages of QIBR QJ series angular contact ball bearings

The QIBR QJ series angular contact ball bearings have multiple characteristics and advantages, which can solve key problems in various fields, mainly reflected in the following aspects;

1. QIBR QJ series angular contact ball bearings have the characteristic of high axial positioning accuracy

The QJ series angular contact ball bearings can provide very small axial positioning tolerances, meeting the high requirements for axial positioning accuracy in applications.

2. The QIBR QJ series angular contact ball bearings have the characteristic of optimized design structure

The QIBR QJ series angular contact ball bearing consists of an integral outer ring, two inner rings, a set of spheres, and an outer ring guide cage. The outer raceway adopts a Gothic arc design, and the inner raceway is divided into two halves for easy assembly.

3. The QIBR QJ series angular contact ball bearings have the characteristic of strong load-bearing capacity that can withstand bidirectional loads

The QJ series angular contact ball bearings can withstand both radial and bidirectional axial loads. In theory, each ball has four contact points with the bearing ring, which can evenly distribute the load.

4. QIBR QJ series angular contact ball bearings have the characteristic of saving axial space

The QIBR QJ series angular contact ball bearings can be regarded as a two in one combination of two single row angular contact ball bearings, with smaller axial dimensions than double row angular contact ball bearings. Suitable for situations with limited space, such as industrial gearboxes, locomotive drive systems, etc.

Performance improvement and solutions for QIBR QJ series angular contact ball bearings

1. Effectively improving material properties and enhancing load capacity

The QJ series angular contact ball bearings use high-quality steel to manufacture the inner and outer rings and ball bearings in production. The surface hardness and material properties are improved through processes such as vacuum heat treatment, enhancing the bearing's load capacity and service life. In addition, the QJ series angular contact ball bearings, due to their special structure, can accommodate more rolling elements, improving their load capacity. By improving the production process, reducing the ring thickness and outer diameter of the bearing, further reducing weight and enhancing load capacity.

For example, adopting thin-walled design can reduce material usage and improve economy while maintaining strength.

2. Optimize internal structural design

The QIBR QJ series angular contact ball bearing consists of an integral outer ring, two inner rings, a set of spheres, and an outer ring guide cage. The raceway design of its outer ring allows for independent definition of contact angle (usually 35 °) and axial clearance, which makes the bearing perform well in terms of load-bearing capacity and service life.
