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.
