HIWIN HGW20HB HGW20CB HGW20 Precision Linear Guide

Structural features

Slider structure: The slider of HGW20HB linear guide usually adopts a four-row arc groove design, which enables the contact point between the steel ball and the groove to form a 45-degree angle. This structural design can provide high load capacity in all directions, including radial, reverse radial and lateral loads, and can effectively cope with complex force conditions to ensure that the slider runs smoothly on the guide rail.

Guide rail structure: The HGW20HB guide rail body is usually made of high-carbon steel, which has high hardness and wear resistance after a special heat treatment process. Its surface is precisely ground and has extremely high straightness, which can provide precise guidance for the movement of the slider and ensure high-precision positioning of the slider during movement.

Circulation system: HGW20HB linear guide is equipped with a smooth steel ball circulation system. The steel balls circulate in the slider, reducing the friction and wear between the steel balls and the track, and improving the movement efficiency and service life of the linear guide. At the same time, this circulation system can effectively evenly distribute the load borne by the steel balls, further improving the overall performance of the linear guide.
