Guideways QW

The guideways of QW series with SynchMotionTM technology by HIWIN company have all the properties of rail guideways of WE series with a wide profile, which show a high level of rigidity of the system for use in a limited space. With SynchMotion technology QE series provides the quiet motion, excellent lubrication and long service life.



 

Accuracy classes

Accuracy classes of QW series are classified into:

  • - normal (C),
  • - high (H),
  • - precision (P),
  • - super precision (SP),
  • - ultra precision (UP).

The choice depends on the equipment requirements.

Preload

Preload for QW series

Definition

The preload can be set for each profile rail guideway. For this purpose oversized balls are used. Usually a negative clearance between the rolling surface and balls is used in the profile rail guideways for increase of the rigidity and accuracy. The curve shows that rigidity doubles with the strong preload. To avoid premature wear of the system, the preload over ZA type is not recommended for profile guideways, size of which is less than 20.

 

Preload classes

There are three types of standard preload for different application conditions.

Class Code Preload Examples of application
Light preload Z0 0-0.02C Certain load direction, low impact, low precision required
Medium preload ZA

0.03C-0.05C

Low load and high precision required
Heavy preload ZB

0.06C-0.08C

High rigidity required, with vibration and impact

 

"C" means the dynamic load capacity in the column "Preload".

Class Interchangeable guideway Non-interchangeable guideway
Preload classes Z0, ZA Z0, ZA, ZB

Dust proof

 

Standard and maximum rail length

 

Hiwin offers a standard rail length to the needs of the client. For non-standard length E recommended size should not exceed 1/2 of the pitch (P). It prevents the instability of the rail end.

 

 

L=(n-1)*P+2*E

L - total length of guideway (mm)
n - number of mounting holes
P - distance between the two holes (mm)
E - distance from the center of the last hole to edge (mm)
