Heavy Load Type Linear Guide Slider For Smooth Movement And Perfect Alignment

Advantages of Arta linear guideway:

-High positioning accuracy, high repeatability

The ARTA linear guideway is a design of rolling motion with a low friction coefficient, and the difference between dynamic and static friction is very small. Therefore, the stick-slip will not occur when submicron feeding is making.

-Low frictional resistance, high precision maintained for long period

The frictional resistance of a linear guideway is only 1/20th to 1/40th of that in a slide guide.With a linear guideway, a well lubrication can be easily achieved by supplying grease through the grease nipple on carriage or utilizing a centralized oil pumping system, thus the frictional resistance is decreased and the accuracy could be maintained for long period.

-High rigidity with four-way load design

The optimum design of geometric mechanics makes the linear guideway to bear the load in all four directions, radial, reversed radial, and two lateral directions. Furthermore, the rigidity of linear guideway could be easily achieved by preloading carriage and by adding the number of carriages.

-Suitable for high speed operation

Due to the characteristic of low frictional resistance, the required driving force is much lower than in other systems, thus the power consumption is small. Moreover, the temperature rising efect is small even under high speed operation.

-Easy installation with interchangeability

Compared with the high-skill required scrapping process of conventional slide guide, the linear guideway can ofer high precision even if the mounting surface is machined by milling or grinding. Moreover the interchangeability of linear guideway gives a convenience for installation and future maintenance.

Static Safety Factor ( f s )

Due to the impact and vibration while the guideway at rest or moving, or the inertia from start and stop, the linear guideway may encounter with an unexpected external force. Therefore, the safety factor should be taken into consideration for efects of such operating loads. The static safety factor ( f s ) is a ratio of the basic static load rating (C 0 ) to the calculated working load. The static safety factor for diferent kinds of application is shown as Table.
