The longitudinal groove or ridge on the guide rail surface is used to guide, fix machine parts, special equipment, instruments, etc. Guide rail, also known as linear guide rail, is used for linear reciprocating motion occasions, has higher rated load than linear bearings, and can withstand certain torque. It can realize high-precision linear motion under high load. With the improvement of people's living standards, cars as an important means of transportation have entered thousands of households. The production and sales of various automobile manufacturers increase every year. The guide rail on the car door glass is also needed, so a left front door glass upper guide rail is needed.
