Features of linear guides
There are many types of linear guides. The simplest classification is roller linear guides, cylindrical linear guides and ball linear guides. The function of the linear guide is to support and guide the parts that need to be moved, and perform repeated linear motions in a prescribed direction. Below, briefly introduce the characteristics of the linear guide.
(1) Self-aligning ability
The DF (45-°45)° combination from the arc groove, during installation, through the elastic deformation of the steel ball and the transfer of the contact point, even if the installation surface is somewhat deviated, it can be absorbed by the inside of the linear rail slider. Produces the effect of automatic centering ability and obtains high precision and stable smooth movement.
Due to the strict control of the manufacturing precision, the linear guide rail size can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off. Therefore, some series of precision are interchangeable. Customers can order guide rails or The sliding block can also be stored separately from the guide rail and the sliding block to reduce storage space.
(3) High rigidity in all directions
The use of four-row circular arc grooves and a 45-degree contact angle of four rows of steel balls allows the steel balls to achieve an ideal two-point contact structure, which can withstand loads from up and down and left and right directions; when necessary, preload can be applied to increase rigidity.
