Ball Screw Catalogue

Selecting and calculating a Hiwin ball screw involves several factors, including the application requirements, load conditions, speed, accuracy, and environmental conditions. Hiwin provides detailed catalogue information for their ball screws, and you can follow these general steps to make a selection and perform basic calculations, also Hiwin detailed Ballscrew catalogue download:

   - Determine the load requirements, both axial and radial.

   - Define the travel distance or stroke length.

   - Specify the desired speed and accuracy for your application.

   - Consider environmental factors such as temperature and contamination.

2. **Refer to Hiwin Catalog:**

   - Obtain the Hiwin ball screw catalogue from the official Hiwin website or your local distributor.

   - Navigate to the ball screw section and find the catalogue or datasheet relevant to your application.

3. **Identify Ball Screw Series:**

   - Hiwin offers various ball screw series, each designed for specific applications and performance requirements. Identify the series that best suits your needs.

4. **Select Ball Screw Size:**

   - Use the load and speed requirements to choose the appropriate ball screw diameter and lead (pitch).

   - Ensure that the selected ball screw can handle both axial and radial loads comfortably.

5. **Calculate Dynamic Load Rating (Life Expectancy):**

   - Calculate the dynamic load rating (C) using the formula:

     \[ C = \frac{{P \times (1000)}}{{\text{{Life Expectancy in millions of revolutions}}}} \]

     Where \( P \) is the applied load.

6. **Check Static Load Capacity:**

   - Verify that the static load capacity of the selected ball screw is sufficient for your application.

7. **Determine Critical Speed:**

   - Calculate the critical speed to ensure the ball screw operates within its safe speed range:

     \[ \text{{Critical Speed}} = \frac{{\text{{Resonant Frequency}}}}{{\text{{Number of Bearings}}}} \]

     Hiwin catalogues typically provide information on the critical speed and recommend operating speeds.

8. **Consider Mounting Orientation:**

   - Consider the mounting orientation of the ball screw, as this can affect its performance. Hiwin provides guidelines on mounting orientations.

9. **Check Environmental Factors:**

   - Ensure that the selected ball screw can withstand the environmental conditions of your application, including temperature and contamination.

10. **Consult Hiwin Support:**

    - If you have specific or complex requirements, it's advisable to consult with Hiwin's technical support or a local distributor. They can provide additional guidance and assistance.

Always refer to the specific catalogue and technical documentation provided by Hiwin for accurate and detailed information. Additionally, performing these calculations may require engineering expertise, and it's recommended to involve a qualified engineer in the selection process for critical applications.
