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.

Hiwin also provides software and online calculators to help with precise selection based on these criteria.
