Comparison between Cross Rail Displacement Stage and Linear Rail Displacement Stage

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

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

PDV instrument displacement stage manufacturers have stated that many manufacturers, considering factors such as cost, accuracy, and installation space, tend to replace linear installation with cross guide rails. So, what is the difference between these two types of displacement stage guides?

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

2. The moving platform of the cross guide rail has a longer lifespan and high rigidity. The displacement stage manufacturer has extended the effective contact length and extended the service life of the track due to its unique roller retention method;

3.The displacement stage products with cross guide rails have better corrosion resistance. Cross guide rails are often made of stainless steel material and have excellent corrosion resistance.

It is precisely because of the above advantages of cross guide rails that more and more users tend to choose cross guide rails when purchasing displacement stages.
