Low profile linear rails are a type of guide used in many industrial automation equipment. The so-called low-assembly guide means that the track plane height of the guide is lower than that of other traditional guides. This article will introduce in detail the application advantages of low-assembly linear guides and the difference between high-assembly and low-assembly.
1. Advantages of Low Profile Linear Rails
The main characteristics of low-profile guides are easy installation and simple maintenance, as well as high stability and positioning accuracy.
Easy installation: Low profile linear rails adopt modular design, and the installation process is simple and fast, reducing installation time and cost.
High precision: Precision manufacturing process is used to ensure the matching accuracy between the guide rail and the slider, providing stable linear motion.
High reliability: The selection of high-quality materials and advanced surface treatment technology improves the wear resistance and service life of the guide rail.
Low friction: The optimized ball or roller design reduces friction during movement and improves movement efficiency.
Strong adaptability: Suitable for a variety of working environments, including high temperature, low temperature, humidity and other harsh conditions.
2. Application Fields of Low Profile Linear Rails
- Optical Detection and Positioning
In optical detection equipment, it is often used for optical path positioning and focal length adjustment. By providing precise and smooth linear motion, it ensures accurate alignment and stable position adjustment of optical components, thereby obtaining high-quality optical measurement and imaging results.
- Automatic Test Equipment Field
It can be used for sample delivery and mobile platform control. By providing stable translational motion, the sample is accurately delivered to the test position to ensure the accuracy and reliability of the test. In addition, in test scenarios that require high-speed movement and rapid response, low-assembly linear guides can also meet the requirements of rapid positioning.
- 3C Electronic Equipment
It is used for positioning and movement control during the assembly and splicing of various components, providing smooth and stable movement, ensuring the precise docking and assembly quality of parts, thereby improving production capacity and production efficiency. In addition, low-assembly linear guides can also be used in the adjustment and calibration of mechanical structures.
3. Low Profile Linear Rails VS High-Assembly Linear Rails
3.1 Low Profile Linear Rails
The combined height of low profile linear rails (from the bottom of the slide to the top of the slider Q) is lower. It has the characteristics of high rigidity, high load, four directions and other loads, and has automatic centering function, which can absorb the assembly error of the installation surface and achieve high precision requirements. Combined with reducing the combination height and shortening the length of the slider, it is very suitable for high-speed automation industries with small mechanical and space requirements.
Suitable for use in environments with small installation space and small load, such as: engraving machines, packaging machinery, semiconductor machinery, etc.
3.2 High Assembly Linear Rails
The combination height of high assembly linear guides is higher, and the difference is between 2~7mm depending on the size of the specification. The reason for this difference is the different slider height specifications. It is a four-row single arc tooth contact linear guide, and it is also a heavy-duty precision linear guide with a good structural design. Compared with other linear guides, it improves the load and rigidity capacity, and the four-way load characteristics and automatic centering function can absorb the assembly error of the installation surface to achieve high precision requirements. The concept of high speed, high load, high rigidity and high precision has become the development trend of industrial products.
Suitable for use in environments with large installation space and large load, such as: grinders, milling machines, lathes, boring machines, drilling machines, integrated processing machines, etc.
In general, the height of the linear guide slider combination determines whether it is a high assembly or a low assembly, and the determining factor is the allowable height of the use plane. The same size, different slider heights, high assembly is the assembly of the guide and slider together, and the relatively low assembly will be slightly higher.
Summary
The compact design and high-precision characteristics of low profile linear rails make them an important part of various industries. They are an ideal solution that can provide efficient and precise linear motion in space-constrained situations.
