Linear rolling guide has a wide range of applications in CNC machine tools and automation equipment. Compared to the sliding rails used in ordinary machine tools, it has the following characteristics:
Firstly, it has high positioning accuracy and is easy to obtain high walking accuracy
Rolling linear guides can reduce the friction coefficient to 1/50 of sliding guides. Due to the small difference in coefficient between dynamic friction and static friction, the motion is flexible, which reduces the driving torque by 90%. Therefore, the positioning accuracy of the machine tool can be set to the ultra micron level.
Secondly, the total cost is low, which significantly reduces the cost of machine tools and saves electricity, resulting in significant energy savings;
Machine tools using linear rolling guides are particularly suitable for repetitive starting and stopping reciprocating movements due to reduced frictional resistance. This can miniaturize the required power source and transmission mechanism, reduce weight, and lower the power required by the machine by 90%, resulting in significant energy savings.
Thirdly, it can achieve seamless and agile high-speed movement
Due to its low frictional resistance, the linear rolling guide has less heat generation performance and can achieve high-speed movement of the machine tool, thereby improving the work efficiency of the machine tool by 20-30%.
Fourth, it can maintain the high precision of the machine tool for a long time
For fluid lubrication of sliding guide surfaces, the motion accuracy error caused by the floating of the oil film cannot be avoided. Therefore, in the vast majority of cases, fluid lubrication is limited to the boundary region, and direct friction generated by metal contact is unavoidable. In this friction, most of the energy is wasted through frictional losses.
On the contrary, rolling contact has low frictional energy consumption, and the frictional loss of the rolling surface is correspondingly reduced in order to keep the linear rolling guide system in a high-precision state for a long time. Meanwhile, due to the relatively low use of lubricating oil, in most cases only grease lubrication is sufficient, which makes the design and maintenance of lubrication systems for machine tools very simple.

Fifth, all directions have high rigidity
The slider of the rolling linear guide rail has a slight or negative gap between it and the guide rail, which can greatly improve the overall rigidity and motion accuracy of the guide rail.
Sixth, a large allowable load
The slider and guide rail are tightly integrated into a large whole, with high rigidity and equal load in all directions, thus having a large load-bearing capacity. Better highlight the performance of applications and unleash their trend capabilities.
Seventh, simple and convenient maintenance, strong operability, high plasticity, and a good choice for industrial automation.
Eighth, efficient mechanical design
Due to the elastic deformation of the steel balls in the rolling linear guide rail, the installation surface error is absorbed, thereby reducing the flatness requirement of the guide rail installation foundation surface and lowering the processing cost in the mechanical industry.
