How to choose the size of the linear guide rail?

When choosing the perfect linear guide for your application, one of the key factors in determining its overall performance and efficiency is size. Each linear guide component, such as the guide and slide, is available in a variety of sizes to suit different load, speed and accuracy requirements. PYG, as an industry pioneer with 20 years of experience in making guides, will give professional guidance on how to choose the right size linear guides to ensure smooth and accurate movement in your application equipment.

1. Determine the maximum carrying capacity:

The first step in choosing the right linear guide size is to understand the maximum load capacity required for the application equipment you are using. The second is to consider the weight of the moving object, including any additional forces or vibrations that may be encountered during operation. Ensure that you choose a linear guide that can carry the total load without compromising performance or safety, so that your application equipment can achieve the highest performance during use.

2. Analyze the desired velocity and acceleration:

The speed and acceleration of the linear guide are the key factors to determine the appropriate size of the guide. Faster application speeds or rapid changes in direction and acceleration require larger tracks to handle higher dynamic loads and maintain stability throughout the motion.

3. Consider stroke length:

For longer strokes, a linear guide that can withstand the relevant forces must be selected. Longer tracks provide greater high rigidity, reducing any potential bending or deflection due to changes in gravity or load. When choosing the size, be sure to consider the entire stroke length to maintain consistent performance.

4. Assess precision and accuracy:

Linear guides are available in a variety of different precision and accuracy levels, such as ordinary, high precision and ultra-high precision. Therefore, the level of accuracy required in your application equipment determines the appropriate size of the linear guide. Keep in mind that higher precision application devices may require larger dimensions to maintain the desired accuracy.

5. Consider available space:

Finally, consider the available installation space for the linear rail system. Make sure that the selected size does not exceed the allotted area to facilitate installation and provide adequate clearance for installation and maintenance.

In any application, choosing the right size linear guide is critical to ensuring optimal performance and service life. By carefully considering factors such as its maximum load capacity, speed, acceleration, stroke length, accuracy requirements and available space, you can make the most precise choice.
