Following are the composition of linear guide rails
1. Rail base
The base of the guide rail is the foundation of the linear guide rail, usually made of iron, aluminum and other materials, and there are mounting holes at the bottom for easy installation and fixing. In practical application, the shape and size of the rail base are designed according to different use needs and application places.
2. Slider
A slider is a moving part on a rail, usually made of metal or plastic. The slider is mainly divided into: ball slider, guide slider, sliding slider, etc., different types of sliders have different characteristics and scope of use.
3. Guides
The guide is mainly composed of two parts, one is the guide block fixed on the slider, and the other is the guide groove fixed on the guide rail. The function of the guide is to ensure that the movement trajectory of the slider is not offset, and has good stability and accuracy during the sliding process.
4. Rail slider
The guide rail slider is a sliding part on the linear guide and the core component of the linear guide. The quality and performance of the guide rail slider directly affects the use effect and life of the linear guide. Generally, the ball sleeve and the guide rail slider are generally used together, which can not only improve the accuracy and rigidity of the guide rail, but also reduce the wear of the slider and the guide rail.
5. Balls
The ball is an important part of the linear guide, which is used to reduce friction and improve the accuracy and speed of the guide. The number of balls and wear resistance are also among the key performance indicators of linear guides.
6. Contact belt
The contact belt is a special material on the linear guide rail, which is used to reduce friction and sound. The contact belt reduces the friction between the guide rail and the slide, which extends the service life of the guide rail and slide and reduces the generation of noise.
7. Stopper
The stop is a safety device on the linear guide, which prevents overtravel or deviation during the movement of the slide. The stopper is generally installed on the stop plate at both ends of the guide rail, and its structure and arrangement are also related to the application site.
8. Springs
The spring is an auxiliary accessory used in linear rail installation, which can adjust the verticality and friction of the rail slide. Springs are usually divided into two types: pressure springs and tension springs, and different springs are selected for use according to the actual situation.
