EGH25CA--EG series Linear Guideways
High-quality linear guide rails should meet the following requirements: 1) High Motion Sensitivity and Positioning Accuracy
Positioning accuracy refers to the capability of the moving component to stop at the specified position as required. Motion sensitivity denotes the minimum stroke that the moving component can achieve smoothly.
2) Superior Accuracy Retention
Accuracy retention is the ability of the guide rails to maintain their original geometric precision during operation. This primarily depends on the wear resistance of the guide rails and their dimensional stability.
3) High Rigidity
Since the guide rail surfaces bear the external forces applied to the moving components, the guide rails must have sufficient rigidity. Thus, increasing the width of the guide rail surfaces to reduce specific pressure and installing auxiliary guide rails are common practices to bear external loads.
4) Smooth Operation
The smoothness of linear rail movement refers to the performance that prevents crawling phenomena during low-speed motion or micro-displacement.
5) Excellent Wear Resistance
Wear resistance of the linear guide ensures that it can maintain the specified operational accuracy after long-term use. Although wear is inevitable, the design should minimize wear and enable automatic compensation or easy adjustment of wear-induced deviations.
6) Strong Vibration Resistance
Vibration resistance refers to the capability of the linear guide pair to withstand forced vibration and impact, while stability denotes the performance of avoiding self-excited vibration under given operating conditions.
7) Resistance to Deformation under Load
Deformation can affect the relative positions and guiding accuracy of components, which is particularly critical for precision machinery and instruments.
