  • Abstract:
  • In machinery, deep groove ball bearings are essential for supporting rotating shafts by reducing friction and noise during force and moment transmission. Known for their suitability in high-speed and low-power applications, these bearings are widely used in equipment such as DC motors, fans, and air conditioners. Bearing selection depends on shaft size, application, and applied loads, typically radial, axial, or combined. Leading manufacturers, like SKF, TIMKEN, and NTN, offer catalogues that specify bearing types, dimensions, load ratings, and factors like geometry and basic load capacity. In this study, a standard 6200 deep groove ball bearing is examined under radial loading using three material types: high-chromium steel (GCr15SiMn), full ceramic (silicon nitride), and a hybrid configuration where the rings and cage are 440C stainless steel, and the balls are silicon nitride (Si3N4). A 3D model of the bearing was designed in CATIA based on standard catalogue dimensions. The analysis includes fatigue life evaluation in ANSYS, cross-validated analytically in MATLAB, along with modal and harmonic response assessments. The natural frequencies and frequency responses were calculated to assess the bearing’s vibration characteristics under various operating conditions. By examining amplitude against frequency, the vibration response was determined, providing valuable insights into the bearing’s behaviour. This comprehensive approach allows for detailed understanding of performance in terms of durability, load-handling capacity, and vibrational stability.
