Question:medium

If a radial ball bearing has a basic load rating of \(50 \text{ kN}\) and desired rating life is \(6000 \text{ hours}\), then the equivalent radial load that the bearing can carry at \(500 \text{ rpm}\) is

Show Hint

Always double check the exponent value matching your bearing profile type: - Ball Bearing: \(L_{10} = (C/P)^3 \implies P = C / \sqrt[3]{L_{10}}\) - Roller Bearing: \(L_{10} = (C/P)^{10/3} \implies P = C / (L_{10})^{0.3}\) Converting hours to millions of revs uses the factor \(\frac{60 \cdot N \cdot L_H}{10^6}\).
