Equivalent Dynamic Load (P)
2880.0N
Axial/Radial Ratio
0.27
Predominantly radial load — standard deep groove ball bearing suitable

Formula Used

P = X·V·Fr + Y·Fa
X, Y factors depend on bearing type, contact angle, and Fa/Fr ratio — obtain exact values from the specific bearing manufacturer's catalog for final design. V = 1 for inner ring rotating (most common case), V = 1.2 for outer ring rotating.
