A linear shaft is a type of mechanical component used in various industrial and commercial applications. It is typically a long and straight rod made of steel or other materials, and is used to support and guide a linear motion system.
Linear shafts are used in a wide range of applications, including robotics, automation, CNC machines, and packaging equipment. They are also used in linear bearing systems, where they provide support for the bearings and guide the linear motion of the machine.
One of the most important features of linear shafts is their precision. They are designed to be straight and have a consistent diameter along their entire length, which ensures smooth and accurate linear motion. They are also available in various sizes and lengths to accommodate different applications and requirements.
Linear shafts can be made from different materials, such as steel, stainless steel, and aluminum. Each material has its own set of advantages and disadvantages, and the choice of material depends on the application and the environment in which it will be used.
In addition, linear shafts can be coated or treated with different finishes to improve their performance and durability. For example, some shafts are coated with chrome to improve corrosion resistance and increase wear resistance.
