To calculate the static load rating for Angular / Radial Contact Ball Bearings, use the following the equation:

C。=f。iZD²cosα

Where:

C。=Load rating Lbs (N)

f。 =Constant static load rating ball bearings (manufacturer provided)

Z   = Number of bearing ball each row

D   =Bearing ball contact angle degrees

I     =Rows of bearing ball
