THK Linear Rails

THK linear rails have a higher rated load than linear bearings and can withstand a certain amount of torque, enabling high-precision linear motion under high load conditions.

Product Details

       THK linear rails are divided into square ball linear railss, double-axis core roller linear rails, and single-

axis linear rails.


       The function of the THK linear motion rail is to support and guide the moving parts to make a

 reciprocating linear motion in a given direction. Depending on the nature of the friction, THK linear

 motion guides can be classified into THK sliding friction rails, THK rolling friction rails, THK elastic friction

 rails, and THK fluid friction rails. Linear bearings are mainly used in automation machinery, such as

 machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear

 bearings and linear shafts are used together. Like THK linear rails are mainly used in mechanical structures

 with high precision requirements.


      1.Application areas for THK linear rails:


      1). THK linear rails are mainly used in automatic machinery, such as machine tools imported from

 Germany, paper bowl machines, laser welding machines, etc. Of course, linear rails and linear axes are

 used.


      2). THK linear rails are mainly used on mechanical structures with relatively high precision 

  requirements.


 Rolling steel balls are used instead of intermediate media between moving parts and fixed elements of

 linear rails. Because the rolling steel ball is suitable for high-speed movement, small friction coefficient

 and high sensitivity, it can meet the working requirements of moving parts, such as tool holders and

 carriages of machine tools. If the force acting on the steel ball is too large, the steel ball is subjected to

 the preloading time for too long, resulting in an increase in the kinematic resistance of the bracket.


     2. Note on the use of THK linear rails:


     THK linear rails are precision parts, so they require a very careful attitude when used. Even if high-

performance linear rails are used, if they are used improperly, the expected performance will not be

 achieved, and the linear rails will be easily damaged. Therefore, the following matters should be noted

 when using THK linear rails:


     1). Prevent corrosion:


     When taking the THK linear rail directly, remove the sweat from your hands and apply high-quality

 mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer.


     2)Keep the environment clean:


     Keeping the THK linear rail and its surroundings clean. Even if the smiling dust that is invisible to the

 naked eye enters the guide rail, it will increase the wear, vibration and noise of the guide rail.


     3)Installation should be careful:


     THK linear rails should be carefully and carefully used during installation. Strong stamping is not

 allowed. It is not allowed to directly hit the guide rails with a hammer. It is not allowed to transmit

 pressure through the rolling elements.


     4)The installation tool should be suitable:


     THK linear rails use special tools with appropriate and accurate installation tools, and try to avoid the

 use of cloth and short fibers.


     5)Cleaning the rail:


     The guide rail and the linear shaft are one of the core components of the equipment, and its function is

 to guide and support. In order to ensure the machine has high machining accuracy, the guide rail and

 straight line are required to have high guiding precision and good motion stability. During the operation

 of the equipment, due to the large amount of corrosive dust and smoke generated during processing, the

 smoke and dust are deposited on the surface of the guide rail and the linear shaft for a long time, which

 has a great influence on the processing precision of the equipment. An etch point is formed on the

 surface of the linear axis of the guide rail to shorten the service life of the device. In order to make the

 machine work stably and ensure the quality of the products, it is necessary to carefully carry out the daily

 maintenance of the guide rails and linear axes.


      NOTE: Please prepare the cleaning rails - dry cotton cloth, lubricating oil.


      The guide rail of the engraving machine is divided into a linear guide rail and a roller guide rail.


      1)THK linear guide cleaning: first move the laser head to the far right (or left side), find the linear

 guide, wipe it with a dry cotton cloth until it is bright and dust-free, plus a little lubricant (can use sewing

 machine oil, do not use oil ), slowly push the laser head a few times to allow the lubricant to be evenly

 distributed.


      2)Cleaning the THK roller guide: Move the beam to the inside, open the end cover on both sides of the

 machine, find the guide rail, wipe the place where the guide rails on both sides are in contact with the

 roller with a dry cotton cloth, then move the beam to clean the remaining place.

     

     3.Development overview of THK linear rails


     The sustained and rapid growth of China's economy has provided a huge market space for THK linear

 guide products. The strong temptation of the Chinese market has made the world focus on the Chinese

 market. In the short period of reform and opening up, China's linear guide manufacturing The huge

 production capacity formed by the industry has made the world look impressive. With the continuous

 expansion of China's power industry, data communication industry, urban rail transit industry, automobile

 industry and shipbuilding industry, the demand for linear guides will also grow rapidly. In the future, the

 linear guide rail industry has great potential for development.
