Product Description:
The linear slide rail is a kind of rolling guide, and the load
platform can easily move linearly along the slide rail with high
precision by means of steel balls making an infinite rolling cycle
between the slider and the slide rail.
Compared with the traditional sliding guide, the friction
coefficient of the rolling guide can be reduced to 1/50 of the
original. Since the starting friction is greatly reduced,
relatively less invalid motion occurs, so it can easily achieve
μm-level feed and positioning.
Coupled with the design of the bundling unit between the slider and
the slide rail, the linear slide rail can bear the loads in all
directions such as up, down, left, right, etc.
The above display characteristics are not comparable to the
traditional slide guide, so if the machine can match the ball screw
, The use of linear slides for guidance will greatly improve the
accuracy and mechanical efficiency of the equipment.

Characteristics:
1. High precision: The manufacturing precision of the guide rail is
extremely high, and can reach the precision of micron level, so
that it can well maintain the linear motion and stability of the
moving parts.
2. Good wear resistance: guide rail materials are usually made of
high hardness, high toughness and wear-resistant materials, such as
steel, copper, aluminum, titanium, etc., which can ensure the
long-term service life of the guide rail.
3. Strong load resistance: the guide rail can withstand large axial
and radial loads, and can meet the requirements of various
specifications of machinery and equipment.
4. High rigidity: The rigidity of the guide rail is good, which can
effectively resist external torque and bending force and ensure the
stability of moving parts.
5. Smooth movement: The surface of the guide rail is specially
treated, the friction coefficient is small, the movement is stable,
and it is not easy to cause stagnation and friction loss.
In short, the guide rail has the characteristics of high precision,
wear resistance, strong load resistance, high rigidity and smooth
movement, making it an important part of various precision
mechanical equipment.
