Product Overview: The QJ 215 Four-Point Contact Ball Bearing
The QJ 215 bearing is a specialized single-row angular contact ball bearing engineered to support axial loads in both directions. With key dimensions of 75x130x25mm, this bearing is designed with unique raceway profiles that allow it to act as a double-row angular contact bearing but within a much narrower axial space. Its four-point contact geometry enables it to handle radial loads and bi-directional axial loads, making it an excellent space-saving solution for complex loading applications.
Manufactured to precise industry standards, the QJ 215 features a split inner ring, which facilitates the inclusion of a larger number of balls, thereby enhancing its load-carrying capacity. This design is ideal for applications where a single bearing must reliably manage combined loads, such as in gearboxes and industrial pumps. As a premier supplier of industrial components, we provide high-quality bearings like the QJ 215 to ensure optimal performance and longevity for your machinery.
