Let's study the comparison between the cross roller guide and the linear slider roller guide.

The advantages of cross roller guide rail include: 1. stable positioning; 2. good resistance to external impacts and self-locking; 3. good cyclic load fatigue; 4. small impact of system linearity error.

Comparison of advantages and disadvantages between cross roller guide rail (hereinafter referred to as A) and roller linear guide rail (hereinafter referred to as B) (taking commercially available products as an example):

Linear accuracy: Generally, A is higher than B, but the highest accuracy of A is not as good as B;

Specification and size: The available specification A is smaller than B, which means that product A on the market does not have a large specification, while product B does;

Rigidity: Similar size A is greater than B. This is more difficult because the minimum specification of brand B is generally greater than the maximum specification of brand A;

Maximum length: The entire length (not connected) B is much greater than A. The maximum length of A is generally below 1000, while B is usually 4000;

Travel: B of the same length is much greater than A. The reason is that A is the same length as the moving part and fixed part, while B's moving part (slider) size can be much smaller than the fixed part (slide rail);

Protection: B is better than A. Because B's moving parts are equipped with dust prevention devices, while A generally does not;

Life: Equivalent or B higher than A. Poor lubrication or improper use is equivalent, otherwise B is higher than A. The vulnerable part of B is the slider, and if the length is large, the cost of replacing the slider is very low (achieving similar original performance with low cost can be considered as extending the service life).
