What is the difference between ball linear guide and roller linear guide?

In the linear transmission components of mechanical equipment, we commonly use ball linear guide, in addition, there is a linear guide called roller. What is the difference between the ball linear guide and the roller linear guide? Interested friends, the introduction of the small series, to understand the difference between the ball linear guide and the roller linear guide.

As the name implies, literally, the difference between ball linear guide rail and roller linear guide rail is the most direct medium in which they roll. The ball linear guide rail uses rigid beads and the roller linear guide uses steel columns. Ball linear guide rail and roller rail, the most important is the difference in bearing capacity.

Roller linear guide in the slider is the application of cylindrical roller bearings, touch the total area is large, can bear a large load, and ball linear guide in the slider is the application of spherical roller bearings, can bear the load relativity is small. The advantage is that the total area of the touch is small, and the corresponding frictional resistance is also small. In general, the ball linear guide is faster, the steel is slightly worse, the roller linear guide speed is slower, but its steel is good.
