What is Guide Rail

Date:2022-10-18 

Guide Rail: A groove or ridge made of metal or other materials that can withstand, fix, guide and reduce friction of moving devices or equipment. Longitudinal grooves or ridges on the surface of a rail used to guide and secure machine parts, special equipment, instruments, etc. Guide rails, also known as slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion occasions. They have a higher rated load than linear bearings, and can bear a certain torque at the same time, and can achieve high-precision linear motion under high load conditions. Guide rails are mainly divided into two categories: roller guide rails and ball guide rails.
The application of guide rails in our daily life is also very common, such as the slip of sliding doors, the chutes on the upper part of curtains, and the rails of trains, etc., which are all specific applications of guide rails. Guide rails can also be used on any machine or equipment that requires sliding, such as elevator guide rails.

Most of the industrial guide rails are made of steel or cast iron. During the long-term use, due to the friction between the two contact surfaces of different degrees, the surface of the guide rail will be scratched and strained to different degrees, which will seriously affect the machining accuracy of the equipment. and production efficiency. Traditional repair methods usually use metal plate affixing or replacement, but require a lot of precise manufacturing and manual scraping, repairing requires many processes and a long construction period. For the scratches and strains of machine tool guide rails, polymer composite materials can be used to solve them. Due to the material's excellent adhesion, compressive strength, and oil and wear resistance, it provides a long-lasting protective layer for components. It only takes a few hours to repair the scratched part of the guide rail and put it into use. Compared with the traditional method, the operation is simpler and the cost is lower.
