One of the best ways to move things through the manufacturing process with great precision and with little friction is using linear rails. A linear system is specifically designed to support the movement linearly. The linearführung have different names such as linear slides, linear guide rails, linear rails, and linear guidance systems. But all name indicates the same function that linear rail moves loads either in horizontally or vertically. The system is used in various industrial applications due to its efficient functions.
How does it work?
In a linear guides system, there are two parts namely linear block and linear rail. Both the parts support the motion of an application. The linear block moves along the straight linear rail backward and forward. Linear blocks are connected to the moving components by mounting to support the motion for the specified components. Through recirculation ball bearings the motion is created along the rails within the blocks. In industries, these days two most basic types of linearführung are used. One type is known to be sliding contact linear motion ad rolling element linear motion. The difference between the two types is how the motion of the linear block occurs along the rail.
Sliding contact:This type of linear guide is considered the oldest type used within the industry. It is due to its simplicity. However, low manufacturing companies use this technique. The major drawback of this linear rail system is its high coefficient of friction compared to other types.
Rolling element:It is one of the mostcommonly used linear guides for most applications. The rolling motion of the block is created using the elements rollers or ball bearings. It is widely preferred linear guide type because of its accuracy, speed, and precision for guide. Also, the manufacturing companies customize it according to your industrial applications.
