Hiwin HG Series Linear Rails

feature

1. Automatic centering ability

The DF (45- ° 45) ° combination from the circular arc groove, during installation, is absorbed by the interior of the track slider due to the elastic deformation of the steel ball and the transfer of the contact point. Even if there is some deviation in the installation surface, it can produce the effect of automatic centering ability and achieve high-precision and stable smooth motion.

2. Interchangeability

Due to strict control over production and manufacturing accuracy, the dimensions of linear guides can be maintained within a certain level, and the slider is designed with retainers to prevent steel balls from falling off. Therefore, some series of precision are interchangeable, and customers can order guides or sliders as needed, or store them separately to reduce storage space.

3. High rigidity in all directions

By using a four column circular arc groove and a 45 degree contact angle with four columns of steel balls, the steel balls achieve an ideal two-point contact structure that can withstand loads from up and down and left and right directions; When necessary, preloading can be applied to improve rigidity.

Application field

1. Linear guides are mainly used in automation machinery, such as machine tools imported from Germany, bending machines, laser welding machines, etc. Of course, linear guides and linear axes are used in conjunction. 

2. Linear guides are mainly used in mechanical structures with high precision requirements. There is no intermediate medium between the moving and fixed components of linear guides, but rolling steel balls are used. Because rolling steel balls are suitable for high-speed motion, have low friction coefficients, and high sensitivity, they meet the working requirements of moving parts such as tool holders and drag plates in machine tools. If the force acting on the steel ball is too large, the steel ball will withstand the preload for too long, resulting in an increase in the resistance of the bracket movement.
