1、Strong Performance: Linear guide rail has high rigidity and high accuracy. High speed does not card. With the characteristics of high standard, high hardness, wear resistance, more stable quality and more durable. 2、High Accuracy: The guide rail adopts for Goethe style four point contact design, which can bear load evenly in all directions(up and down, left and right), which can absorb the assembly error of the mounting surface, and high accurate under high load. 3、Internal Design: The internal ball distribution is reasonable, the gap is uniform, can be use for long time, and the performance is stable. The surface gap is rigorous and smooth, the speed is high, and not easy to be scalded. 4、Wide Application: Guide rail is widely used in machine tools, construction machinery, robots, reducer, iron and steel, metallurgy, textile, mining, printing, aerospace and other industrial fields. 5、Excellent Material: The guide adopts excellent bearing steel, using tempering technology, has long term wear resisting, with super stability, strong bending resistance, not easy to deform and distortion, to ensure linear movement. 1 x Linear Guide Rail Item Type: Linear Guide RailMaterial: Bearing steelModel: HGH25Use: Widely used in machine tools, construction machinery, robots, gear reducers, steel, metallurgy, textiles, mining, printing, aerospace and other industrial fields
