Similarities and differences between linear guide and plane guide

Linear guides and plane guides belong to one of the basic components, but their functions are completely different. We mainly talk about the difference between linear guide rail and plane guide rail.

The role of the linear guide is an important component of the guiding direction. It is fixedly installed on the equipment, but the plane guide is different. It is not fixed, but a basic element that can move freely. In addition, since the size and production standards of linear guides are standard production products, we can also divide linear guides into standard parts categories. Therefore, when manufacturers produce linear guide rails, they need to select and install the guide rail plane and guide rail for correction and adjustment, and ensure that the parallelism of the two guide rails is within an appropriate range.

When installing, whether it is a linear guide rail or a plane guide rail, the installation is relatively simple. However, since the cross-sectional shape of a linear guide presents a geometric shape, this shape carries more than the cross-sectional shape of a planar guide. The reason is that grooves need to be machined on the guide rail of the linear guide, so that smooth sliding of the sliding element can be achieved by means of these grooves.

Linear guide can withstand the force of a straight line, and can withstand the force in other directions. This design is also one of the big differences between linear guides and planar guides. Special attention is also required when choosing. From the appearance, the linear guide is a long metal shell, which is true in itself. The basic material of the linear guide is the profile, but what is the profile used to make the linear guide. Sorted out several common linear rail profiles for you:

Common types of linear guide steel:

1. Chromium-containing steel profiles

For example GCr15, pay attention to the quenching process.

2. Carburized bearing steel profiles

For example, g20crmo, pay attention to the quenching process.

3. Industrial aluminum profile

Industrial aluminum profiles are usually used where the load carrying capacity is low. As we all know, industrial aluminum profiles are alloy materials with aluminum as the main component. The aluminum alloy material is light, the hardness can meet the requirements of the guide rail, and the weight of the equipment can be reduced to a certain extent. The aluminum profile has a bright surface, silvery white, strong luster, good corrosion resistance, and is suitable for medical equipment and equipment. Some linear modules will also use high-strength aluminum alloy materials as the base and aluminum alloy sliding seats.

4. Stainless steel profile

Some Japanese linear guide rail brands, such as the upper silver guide rail, use stainless steel profiles, usually represented by the letter M.

5. Carbon steel profiles

Carbon steel profile is also a linear guide profile that many well-known brands will choose.

In summary, the linear guide profile is generally a metal profile, usually an aluminum profile. Linear guide profiles and linear guide slider profiles generally use industrial aluminum profiles, because industrial aluminum profiles can generally meet the requirements of guide profiles in terms of accuracy and carrying capacity.
