1. What is Static Load on Ball Bearing?

Static Load on Ball Bearing is the load acting onto the bearing when the bearing is not rotating or the bearing is in static condition. It represents the maximum load that the bearing can support without permanent deformation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ C_o = \frac{F \times z}{5} \]

Where:

\( C_o \) — Static Load on Bearing (N)
\( F \) — Force on Ball Bearing (N)
\( z \) — Number of Balls in Bearing

Explanation: The formula calculates the static load capacity by distributing the total force across the number of balls in the bearing with a safety factor of 5.

3. Importance of Static Load Calculation

Details: Accurate static load calculation is crucial for bearing selection and design. It ensures that the bearing can withstand static loads without permanent deformation, which is essential for applications where bearings are subjected to heavy loads while stationary or during startup conditions.

4. Using the Calculator

Tips: Enter the force on ball bearing in Newtons and the number of balls in the bearing. Both values must be positive numbers (force > 0, number of balls ≥ 1).

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the factor 5 in the formula?
A: The factor 5 represents a safety factor that accounts for uneven load distribution among balls and provides a margin of safety against permanent deformation.

Q2: How does static load differ from dynamic load?
A: Static load refers to loads applied when the bearing is stationary, while dynamic load refers to loads applied when the bearing is rotating. Static load capacity is typically higher than dynamic load capacity.

Q3: What happens if the static load exceeds the calculated value?
A: If the static load exceeds the calculated capacity, it may cause permanent deformation of the balls and raceways, leading to premature bearing failure and reduced performance.

Q4: Are there different formulas for different bearing types?
A: Yes, different bearing types (ball bearings, roller bearings, etc.) have different formulas for calculating static load capacity based on their geometry and contact mechanics.

Q5: How accurate is this simplified formula?
A: This formula provides a simplified calculation. For precise engineering applications, more complex formulas considering material properties, geometry, and contact stresses should be used.
