Bearing Static Load
Determine required basic static load rating C0 from static safety factor S0 and equivalent static load P0.
Inputs
Formula
C0 = S0·P0
Static strength governs standing, very slow or shock-loaded bearings.
Fundamentals
Determine required basic static load rating C0 from static safety factor S0 and equivalent static load P0.
This tool computes Bearing Static Load from the formula: C0 = S0·P0
History
Design theory of gears, threads and bearings matured with machine tools and standardisation (AGMA, ISO) since the Industrial Revolution.
Engineering applications
Used for transmission design, joint strength checks and component selection.

Formula
核心计算关系：C0 = S0·P0
输入变量：
- Static safety S0
S0 - Equiv. static load P0
P0— kN
输出结果：
- Required C0
C0— kN
假设/适用：Gearing/thread formulas assume standard, zero-backlash mounting; include error & load factors K_A.
Worked Example
根据公式 C0 = S0·P0，取 Static safety S0 = 1.5；Equiv. static load P0 = 20 kN。
代入计算得：Required C0 = 30 kN。
Key Points
- Gearing/thread formulas assume standard, zero-backlash mounting; include error & load factors K_A.
- Compare stress with allowable stress and keep a safety factor (≥1.5, ≥2 for critical parts).
- For high speed/load also check lubrication, heat and fatigue life, not just static strength.
