Bearings are often unintentionally magnetized during manufacturing or assembly, rather than being intentionally magnetized. One primary way a bearing can become magnetized is through heat-related processes.
Here's a breakdown:
- Hot Riveting: The hot riveting of a brass cage in a cylindrical roller bearing can cause the assembled bearing to become magnetic. The heat and pressure involved during the process can induce a magnetic field within the steel components of the bearing.
In summary, while bearings are not designed to be magnetized, certain manufacturing processes can unintentionally cause magnetization.
