Linear Guide
Linear guides are motion guides commonly used in industrial automation applications to help components move in an accurately and precisely controlled manner without requiring large amounts of energy or effort. Linear guide systems are built up from a variety of components, most notably bearing blocks, carriages, and rails. These components are manufactured by many of the world’s most respected linear products companies and come in many configurations that can be tailor-made for any application.
Types of Linear Guides
There are several different types of linear guides available on the market. The most common are screw, roller or belt driven systems. Screw driven systems use a lead screw or ball screw to move the component along the rail. Roller or belt driven systems move components along the rail with the help of a belt or roller bearing. Each type of system has its advantages and disadvantages and it is essential that you product is specified for the right application.
Choosing Linear Guides
When selecting linear guides, there are many factors that need to be taken into account. These include, load capacity, accuracy requirements, and speed. It is also important to consider the environment in which the system will need to operate, such as temperature, humidity, and other environmental limitations. In addition, there are a wide variety of different components that can be added to the guide such as bearing seals and protective covers, as well as additional features that can be added to the system, such as friction control, preset stops and dampers.
