·Linear guide rail: The V-shaped roller guide rail is made of high carbon bearing steel AISI 52100, and the V-shaped surface has undergone hardening treatment, with a hardness of up to HRC58-HRC62 and a surface roughness of Ra of 3.2 μ m. Other areas undergo chemical blackening surface treatment using cold drawing forming technology to ensure consistency in material density. The surface quenching process is used to harden the V-shaped surface to improve its wear resistance. At the same time, the core still maintains good softness and has a good buffering effect when subjected to impact loads; The material of the flat guide rail is high-carbon steel, and all surfaces have undergone hardening treatment. The hardness can also reach HRC58-HRC62, and the surface roughness Ra is 3.2 μ m. The unpolished surface has undergone black surface treatment, which is aesthetically pleasing and corrosion-resistant;

·The sliding seat plate is made of high-strength aluminum alloy with a surface of 15 μ M Elimination of anodizing treatment;

Linear roller guides are the unsung heroes of many mechanical systems, responsible for ensuring smooth and highly precise linear motion. These remarkable components, often underestimated in their importance, are indispensable in a wide range of applications across various industries. In this article, we will explore the role of linear roller guides, their key functions, and their significance in today's engineering landscape.

Linear roller guides are engineered to facilitate linear motion by minimizing friction and providing accurate guidance to moving components. They typically consist of a rail and a carriage, where the carriage houses cylindrical rollers. The rail, usually made of hardened steel, serves as the fixed reference surface, while the carriage with rollers allows for smooth motion along the rail with minimal resistance.

Key Functions and Benefits:
