The function and working reason of linear guide

linear slider can be divided into: roller linear guide, cylindrical linear guide, ball linear guide, three kinds, is used to support and guide the moving parts, according to the given direction to do reciprocating linear motion. According to the friction properties, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and so on.

Definition of linear guide


Linear guide rail, also known as line rail, slide rail, linear guide rail, linear slide rail, used for high precision or high-speed linear reciprocating movement occasions, and can bear a certain torque, can achieve high precision linear motion under high load. In the mainland called linear guide rail, Taiwan is generally known as linear guide rail, linear slide rail.


Linear guide classification


It is divided into square ball linear guide, double axis core roller linear guide, single axis core linear guide.


Linear guide action


The function of linear guide motion is to support and guide the moving parts to make reciprocating linear motion in a given direction. According to the friction properties, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide, fluid friction guide and so on. Linear bearings are mainly used in automatic machinery, such as machine tools imported from Germany, bending machines, laser welding machines and so on. Of course, linear bearings and linear shafts are matched. For example, linear guide is mainly used in mechanical structures with high accuracy requirements. The moving components and fixed components of linear guide are not medium, but rolling steel balls.


Automatic aligning linear guide


The DF(45- 45)° combination from the arc groove, in the installation, that is, by the elastic deformation of the steel ball and the transfer of the contact point, even if the installation surface is somewhat deviated, can also be absorbed by the inner rail slider, produce the effect of automatic aligning ability and obtain high precision and stable smooth motion.


It has interchangeability


Due to the strict control of manufacturing accuracy, the linear guide size can be maintained within a certain level, and the slider has the design of reholder to prevent the steel ball from falling off, so part of the series accuracy is interchangeable, customers can order the guide or slider according to need, can also be stored separately guide and slider, to reduce storage space.


High rigidity in all directions


Four rows of circular arc grooves, with four rows of steel ball contact Angle of 45 degrees, so that the steel ball to achieve the ideal two-point contact structure, can withstand the load from up and down and left and right directions; When necessary, preloading can be applied to improve rigidity.
