All directions have high rigidity, using a four column circular arc groove, combined with four columns of steel balls and a 45 degree touch viewpoint, allowing the steel balls to reach the desired two-point touch structure, which can accept loads from up and down and left and right directions; When necessary, preloading can be applied to improve rigidity.

Linear guide can be understood as a rolling guide, which is an infinite rolling cycle of steel balls between the slider and the guide rail, allowing the load channel to easily move linearly along the guide rail with high precision, and reducing the friction coefficient by one-fifth of traditional sliding guide. It can easily achieve high positioning accuracy.

The final unit planning between the slider and the guide rail allows the linear guide rail to simultaneously receive loads in all directions, including up, down, left, and right. Its return system and simplified structural planning enable the linear guide rail to move more smoothly and with lower noise. The planning of the guide rail system strives for a large touch area between the fixed and moving components, which not only improves the load-bearing capacity of the system, but also allows the system to withstand the impact force generated by intermittent cutting or gravity cutting, spreading the effect force widely and expanding the area of force reception. To achieve this, there are various shapes of grooves in the guide rail system, with two representative ones. One is called the pointed arch type, which is an extension of a semicircle with a touch point as the pole;

Another type is circular arc shape, which can also achieve the same effect. Regardless of the structural form, the goal is only one, striving for more rolling steel ball radius and rail contact (fixed components). The key factor determining the functional characteristics of the system is how the rolling element touches the guide rail, which is the crux of the problem.

1. Active centering can only come from the combination of circular arc grooves. During installation, even if there is some deviation on the device surface, it can be absorbed by the interior of the track slider through the elastic deformation of the steel ball and the handling of the touch point, resulting in high-precision and stable smooth motion through active centering.

2. Interchangeability is achieved due to strict control over production and manufacturing accuracy. The linear guide rail scale can be maintained within a certain level, and the slider has a planned retainer to prevent steel balls from falling off. Therefore, some series of precision are interchangeable. Customers can order guide rails or sliders as needed, and they can also be stored separately to reduce storage space.
