1. What is Axial Load?

Axial load (or thrust force) refers to the force applied along the axis of a motor shaft. It's an important parameter in motor selection and bearing design, as excessive axial loads can reduce bearing life or cause motor failure.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Axial Load — Force along the motor shaft axis (N)
• Thrust Force — Applied force in axial direction (N)

Explanation: For most motor applications, the axial load is equal to the thrust force applied to the shaft.

3. Importance of Axial Load Calculation

Details: Proper axial load calculation ensures the selected motor and bearings can handle the applied forces without premature failure. Exceeding maximum axial load ratings can lead to bearing damage and reduced motor lifespan.

4. Using the Calculator

Tips: Enter the thrust force in Newtons (N). The value must be positive. The calculator will output the equivalent axial load.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between axial and radial load?
A: Axial load acts along the shaft axis, while radial load acts perpendicular to the shaft axis.

Q2: How does axial load affect bearing life?
A: Excessive axial loads can dramatically reduce bearing life, especially for bearings not designed for axial loads.

Q3: What are typical axial load limits for motors?
A: This varies by motor type and size - consult manufacturer specifications as limits can range from 5% to 50% of radial load capacity.

Q4: When should I be concerned about axial loads?
A: When using belt drives, gear mechanisms, or any application where forces might be transmitted along the motor shaft.

Q5: Can I reduce axial loads on my motor?
A: Yes, through proper alignment, using thrust bearings, or redesigning the mechanical system to minimize axial forces.
