Load = C / P
| From: | To: |
The SKF bearing load calculation determines the load rating ratio for bearings, which is the ratio of the dynamic load rating (C) to the equivalent load (P). This ratio helps in assessing the suitability and expected life of a bearing under specific operating conditions.
The calculator uses the formula:
Where:
Explanation: The ratio C/P indicates the bearing's capacity to handle the applied load. A higher ratio generally means the bearing is operating well within its capacity, potentially leading to longer service life.
Details: Accurate load calculation is essential for proper bearing selection, predicting bearing life, and ensuring reliable operation of mechanical systems. It helps prevent premature bearing failure and optimize maintenance schedules.
Tips: Enter the dynamic load rating (C) and equivalent load (P) in Newtons (N). Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is dynamic load rating (C)?
A: The dynamic load rating is the constant radial load that a bearing can theoretically endure for a basic rating life of 1 million revolutions.
Q2: What is equivalent load (P)?
A: The equivalent load is the constant radial load which, if applied, would have the same effect on bearing life as the actual combined loads.
Q3: What is a good C/P ratio?
A: A higher C/P ratio is generally better, indicating the bearing is operating well within its capacity. The specific required ratio depends on application requirements and desired service life.
Q4: How does this relate to bearing life calculation?
A: The C/P ratio is directly related to bearing life through the formula L10 = (C/P)^p, where p is 3 for ball bearings and 10/3 for roller bearings.
Q5: Can this calculator be used for all bearing types?
A: While the basic C/P concept applies to most rolling bearings, specific calculations may vary for different bearing types and configurations. Always consult manufacturer specifications for precise calculations.
