What material are linear guide rails generally made of?

Generally speaking, there are two kinds, medium carbon steel and stainless steel. Generally speaking, stainless steel is austenitic. According to different applications, medium carbon steel can be coated to prevent rust and corrosion. Stainless steel is generally a miniature guide rail, which is widely used in electronic industry. Medium and large guide rails can also be customized, but the price is very high.

TTW linear slider can be divided into three types: roller linear slider, cylindrical linear slider and ball linear slider, which are used to support and guide the moving parts to make reciprocating linear motion in a given direction. According to the different nature of friction, linear motion guide can be divided into sliding friction guide, rolling friction guide, elastic friction guide and fluid friction guide. Linear guide rail, also known as line rail, slide rail, linear guide rail and linear slide rail, is used for linear reciprocating motion. Compared with linear bearing, it has higher rated load, can bear certain torque, and can realize high-precision linear motion under high load. It is divided into square ball linear guide, double-axis core roller linear guide and single-axis core linear guide. It is called linear guide rail in Chinese mainland and linear guide rail and linear slide rail in Taiwan Province Province.
