Hiwin Linear Guideway Load Calculator

Hiwin linear guide size calculator

To calculate the size and selection of a Hiwin linear guide, you must consider various factors such as load, speed, accuracy, and environmental conditions. The steps below outline the basic process:

1. Load Calculation:

Dynamic Load (F): The load applied to the linear guide during operation.

Static Load (P0): The maximum load applied to the guide when stationary.

2. Moment Loads:

Consider the three moments (Mₓ, Mᵧ, M𝓏) based on how the load is applied to the linear guide system.

3. Life Expectancy:

Basic Dynamic Load Rating (C): This is provided in the catalogue and helps calculate the guide's life.

Life Calculation (L):L=(CF)3×50 kmL=(FC )3×50 km. This formula is commonly used for life expectancy in kilometres.

4. Load Factor:

Apply a safety factor (Fs) to account for varying operating conditions (vibration, impact).

5. Accuracy Class:

Choose the accuracy class based on the precision requirement (e.g., Normal, High, Precision).

6. Environmental Considerations:

Consider if the guide will be exposed to dust, water, or high temperatures, and choose an appropriate sealing and lubrication system.

7. Size Selection:

Once all factors are considered, select the guide size from Hiwin's catalogue that meets your load, moment, and life requirements.
