When we use a linear guide, we generally only know that it is steel, but we don't pay much attention to specific materials. Observe it carefully, we will also find that the color of some linear rails is different from the naked eye. In addition to the surface coating, there will be different colors, different materials and different colors. What materials are made of linear rails?
Let's first understand what linear guide is. Linear guide rails, also known as TTW linear guide rails, can be divided into three types: roller line -line guide rails, roller line -line guide rails and rolled beads. It is used to support and guide load -bearing components in the specified direction. If the nature of the rubbing is defined, the straight -line guide rail can also be divided into sliding friction guide rails, rolling friction rails, elastic friction rails, fluid friction guide rails and other types.
Of course, we also know that the straight -line guide can also be called line rails, slide rails, linear guide rails, linear slide rails, and line -up movement. Its rated load is higher than the linear bearing. At the same time, it can withstand a certain torque and achieve high -precision linear movement under high load. It is divided into a square ball linear guide rail, a double -axis roller line -up guide rail and a single -axis straight guide rail. It is called a linear guide in mainland China, and it is called a linear guide in Taiwan.
After understanding this, we knew the application of the linear guide. It is necessary to know what materials it uses. There are two kinds of materials in the linear guide rail. The first is medium -carbon steel and silver -plated steel, also known as ordinary steel. In the model, it is usually marked as HC (ordinary steel+hard chrome) or NC (ordinary steel+chemical black chromium). The second is stainless steel, which is marked as M, and is generally Austeen stainless steel. According to the different uses of medium carbon steel, rust -proof and corrosive coating can be performed. Stainless steel guide rails are generally small and are widely used in the electronics industry. Of course, large and medium -sized rails can also use stainless steel, but the price will be very high.
