Today, PYG will give you a popular science about the four characteristics of linear guide rails, in order to help some new people in the industry and guide users have a quick cognition and outline concept of guide rails.
Linear guide has the following characteristics:
1. High rigidity in all directions
The four-row circular arc groove and the 45-degree contact Angle of the four-row steel balls are used to make the steel balls reach the ideal two-point connection
The contact structure can withstand loads from up, down and left and right directions and can apply prepressure to improve rigidity if necessary.
2, with interchangeability
Due to the strict control of manufacturing accuracy, the size of the linear track can be maintained within a certain level, and the slider has a guarantee
The device is designed to prevent the ball from falling off, so some series accuracy is interchangeable, and customers can order guides or sliders as required
Guide rails and sliders can also be stored separately to reduce storage space.
3, automatic aligning ability
The DF(45-°45)° combination from the arc groove, through the elastic deformation of the steel ball and the transfer of the contact point at the time of installation, even if the mounting surface is somewhat deviated, it can be absorbed by the inside of the line rail slider, resulting in the effect of automatic aligning ability and obtain a high precision and stable smooth movement.
4, the linear guide rail is composed of steel balls in the infinite rolling cycle between the slider and the guide rail
Thus, the load platform can easily move along the guide rail with high precision, and the friction coefficient can be reduced to one-fiftieth of the usual traditional slide guidance, and high positioning accuracy can be easily achieved.
