OID / ENGINEERING TOOLS
Static safety
Compare the maximum load against the load rating and the requirement of the selected régime.
The specific bearing's data is entered manually.

How to determine the inputs
Open the explanation, pick the applicable table, or step through the worked example.
Methodology and limits of applicability
OID, ch. 5, §5.3; table D
s₀ = C₀ / P₀
Margin relative to the criterion = s₀ / s₀ req.
Margin relative to the criterion = s₀ / s₀ req.
Input coefficients and requirements must correspond to the specific construction and duty. Missing values are never substituted automatically.
The life, static-safety and minimum-load checks are independent. Slewing bearings, linear systems, plain bearings and small oscillation angles need an applicable specialized model.
