FEATURES
It also features the same load in four directions and self-aligning capability to absorb installation-error which can achieve high accuracy.Besides, the lower assembly height and the shorter length make the EG series more suitable for the high-speed automatic machines and the applications where space limit is considered.

APPLICATIONS
1. Automatic equipments
2. High speed transfer equipments
3. Precision measuring equipments
4. Semiconductor manufacturing equipment Woodworking machinery

Failure mode: denudation

EG Series Low Profile Ball Type Linear Guideway

Denudation failure is a kind of fatigue failure of materials. In general, it is due to the influence of the maximum shear stress, resulting in cracks under the surface of metal materials. Because of the continuous effect of the maximum shear stress, cracks under the surface will extend to the surface, resulting in denudation.

The main causes are as follows
The service life is inconsistent, the load is too heavy, the lubrication is poor, and the foreign body invades.

Failure mode: corrosion

EG Series Low Profile Ball Type Linear Guideway1

After the oil film is removed, the water, acid and alkali solutions will directly adhere to the exposed metal parts, which will reduce the lubricity and lead to rail corrosion, which will be the cause of early denudation.

The main causes are as follows
Poor storage condition, water-soluble coolant intrusion, high humidity environment.

Failure mode: water solution invasion

EG Series Low Profile Ball Type Linear Guideway2

With the invasion of water-soluble coolant, the lubrication and anti rust ability will decrease, resulting in the corrosion of linear slide rail. And then cause erosion.
The main causes are as follows
High humidity environment, water solution intrusion.

Failure mode: burn

EG Series Low Profile Ball Type Linear Guideway3

Because of the heat generated by friction, there will be discoloration, low hardness and poor lubrication of the rotating body, which will lead to most of the very small melting traces on the track, making the rolling surface uneven and eventually leading to denudation.
The main causes are as follows
Poor lubrication and overload

Failure mode: rupture

EG Series Low Profile Ball Type Linear Guideway4

Excessive load leads to poor circulation of the rolling element, which leads to abnormal wear and stress concentration of the track, resulting in fracture.

The main causes are as follows
The external impact force is too large and the rolling element circulation is poor.

Failure mode: indentation

EG Series Low Profile Ball Type Linear Guideway5

When the oil film disappears at the contact point of rolling body under micro inch motion, the relative sliding friction between metal and metal results in the generation of fine powder. The continuous friction of micro powder will cause the indentation between ball spacing and accelerated wear and micro powder. The indentation state will be affected by the roughness of rolling surface and the thickness of oil film.
The main causes are as follows
Micro inching, poor lubrication and overload
