    What is Linear Guideways?

    Linear guideways, also known as line rails, are used in high-precision or high-speed linear reciprocating motion applications. They can bear a fixed torque and can achieve high-precision linear motion under load.
    Linear rails can be divided into roller linear guides, cylindrical linear guides, and ball linear guides. According to the nature of friction, linear motion guideways can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc. 300mm ~ 1500mm CNC linear rails with a guide block are available on

    It can be understood as a kind of scroll guide. It is an infinite rolling cycle of steel balls between the slider and the guide rail so that the load platform can easily move linearly with high precision along the guide rail, and the friction coefficient is reduced to one-fifth of the ordinary traditional sliding guide, which can easily achieve high positioning accuracy. The design of the final unit between the slider and the guide rail enables the linear guide rail to bear the loads in all directions such as up, down, left and right at the same time. The patented return system and simplified structure design make the linear guides move more smoothly and with low noise.

    3 functions of linear guide rails

    It is well known that there are various forms of CNC linear rails, and there are quite a number of applications industries, but in fact, the working nature is roughly the same. The moving parts of CNC machine tools on specific rails are equivalent to trains traveling along the rails to each station. We can clearly see from the way the two movements that the linear guide has the following three functions:

    • To guide the movement of the carrier
    • Provide a smooth moving surface for the carrier
    • The force generated by the movement of the train or the cutting of the machine tool is transmitted to the foundation or the bed to reduce the impact of the resulting impact on passengers and passively machined parts.

    The function of the linear guide is to support and guide the moving parts and rely on the two or four rows of balls on both sides of the guide to roll and drive the table to move smoothly in a given direction to make a reciprocating linear motion. Most of the movement along the guide rail system is linear movement, and a few are arc movement.
