Key Takeaways: Bearings are fundamental parts of machinery, supporting rotational movement and bearing loads. There are various types of bearings, including ball bearings, roller bearings, plain bearings, and magnetic bearings. Ball bearings are known for their simple structure, low friction coefficient, and highspeed capabilities.

X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r. P o = Axial load and is equal to P o = + Where, F r is the radial force and F a is the Axial Force.
