Today, the evaluation of linear guide system is no longer limited to technical indicators such as bearing capacity, stiffness and accuracy. Equally important are the maintenance requirements with the least ability to prevent pollutant intrusion and the reliability of continuous shift operation. In order to meet such requirements, it is necessary to have proper sealing system, lubricant storage chamber and long-term lubrication unit.
The traditional linear guide system can not meet all the above requirements. Some of them cannot be realized due to technical reasons, while others are due to the consideration of production costs. Therefore, people have designed various linear guideway systems to meet the requirements in some specific application fields. For example, in some situations where standard linear guide rails are used, the insufficient amount of lubricant will directly lead to a significant decline in the life of the guide rails. Here, lubricant is a key factor for reliable operation of guide rail. Therefore, a shorter lubricant replenishment cycle should be selected to prevent the life of the guide rail from being damaged due to insufficient lubrication.
For some seriously polluted applications, the design has to face completely different problems. If not properly designed
For the dirt protection of the raceway and rolling element, the wear phenomenon will be very serious.
The standard linear guideway system is not suitable for all applications
The use of the standard linear guide system can be summarized as two points or its scope of use can be limited; It is difficult to refit the proper sealing and lubricating system for it in some applications. In order to have sufficient configuration options for various specific applications
Therefore, the concept of modular design must be introduced into the design of relevant equipment components.
SOMA series ball rolling body linear guide system produced by SMG linear guide factory in Japan and China is a good example of modular design concept. This is a four row roller linear guide system, which is suitable for various existing linear guide applications in the machine tool manufacturing field. This linear system includes a sliding block with a ball circulating bearing and a guide rail. The sliding block passes through the pre loading before installation.
According to different sizes and designs, this linear system can replace the traditional wedge guide rail and sliding guide rail systems.
The various improvements in design enable SOMA linear guide system to have excellent performance beyond the traditional linear guide system, while maintaining a good cost performance ratio. Now this maintenance free linear guide system can be used in various applications after selection.
