Method
Formula, when it applies, and when it does not
Calculate equivalent dynamic load, reverse basic rating, static ratio, DN, and preload ratio from bearing-specific inputs.
P = XFr + YFa; Creq = P·L10^(1/p); static ratio = C0/P0; DN = d·n
When
- User-entered X/Y factors
- Constant load direction
- Basic rating-life arithmetic
- User-entered DN limit
Don’t
- This is constant-load basic rating arithmetic using user-entered bearing-specific X/Y factors, exponent, static load, and DN limit. It does not select a bearing, provide factor or limit values, model variable duty, use a modified-life method, assess lubricant/contamination/temperature, determine preload or stiffness, assess static adequacy, or replace a bearing manufacturer calculation.
