Bearing Size Calculator

How to Use the Calculator?

1. Input Values:
   • Inner Diameter (coixinets de ceràmica 8X22X7mm Especificacions i dimensions): Enter the diameter of the hole inside the bearing (in millimeters).
   • Outer Diameter (coixinets de ceràmica 8X22X7mm Especificacions i dimensions): Enter the diameter of the outside of the bearing (in millimeters).
   • Length: Enter the length of the bearing (in millimeters).
2. Perform Calculations:
   • Inner Circumference: The distance around the inner edge of the bearing. Calculated using the formula: Inner Circumference=π×ID\text{Inner Circumference} = \pi \times \text{coixinets de ceràmica 8X22X7mm Especificacions i dimensions}Inner Circumference=π×ID
   • Outer Circumference: The distance around the outer edge of the bearing. Calculated using the formula: Outer Circumference=π×OD\text{Outer Circumference} = \pi \times \text{coixinets de ceràmica 8X22X7mm Especificacions i dimensions}Outer Circumference=π×OD
   • Volume: The amount of space inside the bearing, excluding the inner cylindrical hole. Calculated using the formula: Volume=π×((OD2)2−(ID2)2)×Length\text{Volume} = \pi \times \left( \left(\frac{\text{coixinets de ceràmica 8X22X7mm Especificacions i dimensions}}{2}\right)^2 – \left(\frac{\text{coixinets de ceràmica 8X22X7mm Especificacions i dimensions}}{2}\right)^2 \right) \times \text{Length}Volume=π×((2OD​)2−(2ID​)2)×Length
3. View Results:
   • After entering the values and clicking the “Calculate” button, the calculator displays:
     • Bearing Size: Shows the inner diameter, outer diameter, and length as entered.
     • Inner Circumference: The circumference of the inner part of the bearing.
     • Outer Circumference: The circumference of the outer part of the bearing.
     • Volume: The calculated volume of the bearing in cubic millimeters.

Example Calculation:

Let’s say you enter the following values:

• Inner Diameter (coixinets de ceràmica 8X22X7mm Especificacions i dimensions): 10 mm
• Outer Diameter (coixinets de ceràmica 8X22X7mm Especificacions i dimensions): 20 mm
• Length: 50 mm

The calculator performs these calculations:

• Inner Circumference: π×10≈31.42 mm\pi \times 10 \approx 31.42 \text{ mm}π×10≈31.42 mm
• Outer Circumference: π×20≈62.83 mm\pi \times 20 \approx 62.83 \text{ mm}π×20≈62.83 mm
• Volume: π×((202)2−(102)2)×50≈2,356.19 mm3\pi \times \left(\left(\frac{20}{2}\right)^2 – \left(\frac{10}{2}\right)^2\right) \times 50 \approx 2{,}356.19 \text{ mm}^3π×((220​)2−(210​)2)×50≈2,356.19 mm3

The results will be displayed, showing the calculated circumferences and volume based on the input dimensions.
