In order to understand how a linear rail benefits homes, businesses and the society as a whole, it's important to understand what the device is. A linear rail is also known as a linear slide. It's a channel that helps convey materials in an efficient fashion.

One way to understand how a linear rail does its thing is to imagine it as a skateboard. In order for the board to work, there is a platform upon which to skate on. Also, the wheels of the board are necessary to help steer the user in the right direction and in a speedy fashion.

One big difference, conceptually speaking, is that the board isn't attached to the platform. This enables the skateboard operator to go away at any time. A linear rail, however, rarely has this luxury.

Although it is not glued to the platform, the conventional slide is held in place on both sides of the platform by means of a curvature. This way, the slide cannot detach from the platform by accident. Eventually, however, the device would evolve into a velocipede or pump-trolley-like function as it runs through a platform.

Therefore, by their construction and design, this type of rail is nothing but a conduit for giving almost anything a smooth ride. Food, raw materials, machine parts, and an endless array of things all benefit from being conveyed in this linear fashion. An automated car wash system follows the same principle.

A new transportation concept recently unveiled by the Chinese government harnesses the principle for solving the traffic issue. With slide-like formations coasting along a busy highway, more vehicles can travel through the road, thus easing congestion. Tesla Motors also introduced a similar prototype recently, which enables cars to travel in the same fashion at top speed while avoiding a collision.

These are examples of the linear slide concept from the macro point of view. It is in manufacturing where micro applications of the same principle can be found in an assembly line fashion. One example is a 20mm linear rail with a 30-inch-long ramp. With a square slide unit, it's guaranteed to run smoothly. High repeatability is a requirement for this rail. This device cannot work alone.

It needs an equally reliable roller-ball or bearing in order to make it move on a straight path. As a whole, the contraption can be used for display, demonstration, lab experiments, and intensive manufacturing runs. The makers stake their reputation on the longevity, durability, and efficiency of their brands. They must run a straight line without fail or they can affect the quality of the finished product that they are putting on the line.

When they come with balls rather than bearings, this army of assembly line conveyors is called roller slides. Otherwise, the champions of linear motion are associated with all types of bearings such as dovetail, linear, magnetic or fluid. Roller slides are likewise commonly used in clean instead of dusty production environments because by nature, they are not self-cleaning, unlike their bearing counterparts.

What's the similarity between a sober man and a working linear motion bearing? Answer They could both walk a straight line. In the final analysis, a roller slide that can't travel on a straight line isn't drunk--it's simply defective.
