Comparison between cross guide rail displacement stage and linear guide rail displacement stage

In optical displacement stage products, there are two common guide rails: cross guide rail and linear guide rail, which have different functions in different occasions. Next, let's take a look at the differences between different guide rail displacement stage products with PDV displacement stage manufacturers.

The cross guide rail type displacement stage uses a unique method to increase the effective contact length of the roller and shorten the roller pitch. After special heat treatment, it is combined with the precision machined special V-shaped track. It has the characteristics of high rigidity and high precision. This type of track is widely used in optical worktable, optical tester and other products, including displacement stage products.

Considering the cost, accuracy, installation space and other factors, many manufacturers prefer to replace the linear installation with the cross guide rail. So, what's the difference between the two kinds of displacement platform tracks?

1. The installation height of the cross guide rail is lower, and the stability of the machine in operation is much higher than that of the linear guide rail;

2. The displacement stage with cross guide rail has longer service life and high rigidity. Because of its unique roller holding method, the cross guide rail displacement stage extends the effective contact length and makes the track have a longer service life;

3. The displacement stage of cross guide rail has better corrosion resistance. The cross guide rail is often made of stainless steel, which has excellent corrosion resistance.

It is precisely because of the above advantages of cross guide rail that more and more displacement stages are used. When selecting displacement stages, manufacturers prefer to choose cross guide rail.
