Product Details

When machine that vectoring by linear guide ,the friction coefficient will be 1/50 of sliding friction coefficient, there will be no slipping phenomenon and the positioning.

Arc groove design of the front combination makes the linear guideway has the ability to automatically adjust the center, even if to give preload it can absorb installation error.

Linear guides are mainly used in mechanical structures with line adapter, detector, office machine, transmission machine, semiconductor machinery etc.

Introduction to linear bearings:

Linear bearings are linear motion systems used for linear strokes in conjunction with cylindrical shafts. Since the bearing ball is in contact with the bearing shell, the steel ball rolls with the minimum frictional resistance. Therefore, the linear bearing has small friction and is relatively stable, and does not change with the bearing speed, and can obtain high sensitivity and high smooth linear motion. Linear bearing consumption also has its limitations. The most important thing is that the bearing impact load capacity is poor, and the bearing capacity is also poor. Secondly, the linear bearing has large vibration and noise during high-speed motion. Linear bearings are widely used in sliding parts of industrial machinery such as precision machine tools, textile machinery, food packaging machinery, and printing machinery.

Introduction to linear guides:

The function of the HIWIN linear guide motion is to support and guide the moving parts to make a reciprocating linear motion in a specified direction. Depending on the nature of the friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. The linear guide rail is mainly used on a mechanical structure with high precision requirements. The intermediate medium is not used between the moving component and the fixed component of the linear guide rail, and the rolling steel ball is used.

 

Flexure bearings rely on elastic properties of material.Flexure bearings bend a piece of material repeatedly. Some materials fail after repeated bending, even at low loads, but careful material selection and bearing design can make flexure bearing life indefinite.
