The most effective method for testing ball bearings is through induced current shots along the X, Y, and Z axes while rotating 360 degrees during each shot. This approach allows for comprehensive coverage of the bearing's surface and internal structure. By inducing an alternating current through or around the bearing, defects such as cracks, laps, or porosity can be detected through the magnetic fields created. The rotation and selection of multiple axes ensure that any anomalies in the material or surface can be identified from various angles, enhancing the sensitivity of the detection process.

In contrast, static magnetic tests may not provide the same level of detail or effectiveness because they typically rely on establishing a magnetic field without the nuanced inspection capabilities that dynamic methods like induced current shots offer. Magnetic field interpolation and high-frequency alternating current, while they have their applications, are not as broadly suited for detecting the specific types of defects commonly found in ball bearings compared to a comprehensive approach that includes multiple orientations and magnitudes of induced current. This combination increases the likelihood of revealing critical flaws that could impair bearing performance.
