Cross roller guides and linear guides are both types of linear motion systems used in various applications.However,there are some key differences between them:
Cross Roller Guide
Linear Guide
From the structural,cross guide rail is a split structure,which is more complicated than the linear guide rail when assembled.Functionally,cross guide rail is suitable for short stroke,high frequency,high precision occasions.
The linear guide rail can achieve a single length of 6000mm,but also can butt longer,the transmission mode is Goethe groove structure, the middle is the steel ball transmission,but the service life is not as good as the cross guide rail;
In terms of sealing,the linear guide rail is much better than the cross guide rail,and the linear guide slide block itself has a lubricating oil nozzle.
Cross guide rail is a kind of limited linear motion system with high rigidity,high precision and compact.The effective contact length of the roller cylinder is increased by using the unique roller retention mechanism of R-type roller retainer,which shorens the distance between the roller cylinders.
Different from the linear guide rail,the installation height of the cross guide rail is lower,because it is a parallel installation combination of two guides into a set,making the machine integrity of the cross guide rail is better than the linear guide rail, the overturning moment is higher than the linear guide rail,so the stability of the machine is much higher than the linear guide rail.
