Spindle Spacing Calculator


In engineering and manufacturing processes, precise calculations are crucial for achieving accurate results. One such calculation often encountered is determining spindle spacing. Spindle spacing refers to the distance between two rotating components, such as gears or pulleys, mounted on a shaft. This article presents a spindle spacing calculator, along with a detailed guide on its usage and implementation.

How to Use

To utilize the spindle spacing calculator, follow these steps:

  1. Input the required parameters, such as the diameter of the rotating components and the desired center distance, into the designated fields.
  2. Click the “Calculate” button to obtain the calculated spindle spacing.
  3. Review the result provided by the calculator for the precise spindle spacing value.


The spindle spacing calculation involves the following formula:


  • d1​ is the diameter of the first rotating component.
  • d2​ is the diameter of the second rotating component.
  • “Center Distance” represents the desired distance between the centers of the rotating components.

Example Solve

Let’s consider an example:

  • d1​=10 cm
  • d2​=8 cm
  • Center Distance = 15 cm

Using the formula:

Thus, the calculated spindle spacing is 24 cm.


Q: What are the primary parameters required for spindle spacing calculation?

A: The primary parameters required are the diameters of the rotating components and the desired center distance between them.

Q: Can this calculator handle different units of measurement?

A: Yes, the calculator is versatile and can handle various units, such as centimeters, inches, or millimeters, as long as consistent units are used for all inputs.

Q: Is there any limitation on the size or type of rotating components for this calculation?

A: No, the calculation is applicable to any type or size of rotating components as long as the input parameters are accurate.


The spindle spacing calculator provides a convenient tool for engineers and manufacturers to accurately determine the distance between rotating components. By inputting the necessary parameters into the calculator, users can swiftly obtain precise spindle spacing values, streamlining the design and assembly processes.
