Materials and classifications used for linear guides

An expert in the field of linear guides - Shandong Jingrui Transmission Technology Co., Ltd. Today, we will introduce to you the materials and classifications used in linear guides.
Our series of products represented by Mgn12h Mini Linear Rail Guide have become models and benchmark products in the industry, and have won the favor of the majority of buyers.
1. Materials used for linear guides

1. Many linear guide materials use chromium bearing steel, common ones such as GCr15, and carburizing bearing steels such as G20CrMo can also be considered. Structural design should pay attention to the quenching process requirements, otherwise there will be cracking and deformation.

2. Linear sliders can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts and perform reciprocating linear motion in a given direction. Depending on the nature of the conflict, linear motion guides can be divided into sliding conflict guides, rolling conflict guides, elastic conflict guides, and fluid conflict guides.

Second, the classification of linear guides

1. The linear guide pair is generally composed of guide rails, sliders, reversers, rolling bodies and stickers, etc. It is a new type of rolling support for relative reciprocating linear motion, which can roll with the steel ball between the slider and the guide rail. Instead of a direct sliding touch, the rolling body can complete an infinite loop in the raceway and the slider with the help of a reverser, with a simple structure,

2. The advantages of small dynamic and static conflict coefficient, high positioning accuracy and good accuracy persistence. Linear guides, also known as fine tumbling linear guides, slide rails, linear guides, linear slides, and tumbling guides, are used in linear reciprocating motion occasions that require accurate control of the parallelism of the table, and have a higher rated load than linear bearings. It can bear a certain torque and can complete high-precision linear motion under high load conditions.

3. The function of the linear guide is to support and guide the moving parts. Relying on the two or four rows of balls on both sides of the guide, the cyclic tumbling drives the worktable to move smoothly in a given direction to make a reciprocating linear motion. Depending on the nature of the conflict, linear motion guides can be divided into sliding conflict guides, rolling conflict guides, elastic conflict guides, and fluid conflict guides.
