Guideways QE

Development of the linear motion systems of QE series by HIWIN company is based on creation of a larger contact area of the rolling elements and circulation paths. The guide paths are made in an arc shape, so the contact with the balls occurs at four points. The SynchMotion technology was applied here as in the linear guideways of QH series, thereby the series has the quiet operation, smooth motion, excellent lubricant ability and therefore, a long service life. The guideways of QE series got all features of EG series, so they can be used in high-tech technologies. QE and EG series use identical rails, therefore the carriages of this series can be used interchangeably.

Accuracy classes

Accuracy classes of QE series are classified into:

  • - normal (C),
  • - high (H),
  • - precision (Р),
  • - super precision (SP),
  • - ultra precision (UP).
The choice depends on the equipment requirements.

Preload

Preload QH

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 Condition
Very Light Preload Z0 0-0.02C Certain load direction,low impact, low precision required
Light Preload ZA

0.03C-0.05C

Low load and high precision required
Medium Preload ZB

0.06C-0.08C

High rigidity required, with vibration and impact

 

Note: The "C" in the preload column denotes basic dynamic load rating.

Class Interchangeable Guideway Non-Interchangeable Guideway
Preload classes Z0, ZA Z0,ZA,ZB
