The name of the linear optical axis and the linear guide are very similar, and the function is also very similar, so that many people will not be able to tell the difference between them. Both the linear optical axis and the linear guide have a good development in the field of machinery manufacturing and are loved by many users. They are mainly responsible for support and guidance. The main difference is the installation location. So today, let's take a look at the difference between a linear optical axis and a linear guide. If you are interested, let's take a look!
Straight optical axis
The main difference between the linear optical axis and the linear guide rail is the installation location, and the shape is also different. The optical axis is circular, and the linear guide rail is generally square and has a fixed installation slider on it. The linear optical axis is generally fixed at both ends, and the middle suspended connecting part covers all or most of the radial direction of the optical axis. Linear guide rails generally have one side all closely attached to the equipment mounting base and are fixed with bolts.
The linear optical axis is a product with the guiding function of the sliding bearing, which enables the implementation of linear motion. The necessary conditions required for these linear motion systems are: simple design, best execution capability, low maintenance costs, and strict selection of sturdy and durable use. material, high frequency heat treatment, accurate outer diameter, roundness, straightness and surface treatment. Linear optical axes are widely used in many linear motion systems such as cylinder rods, automatic precision printers, automatic cutting machines and industrial robots.
The linear guide refers to the rolling guide, which is the kind used in the linear modules often used in the machine tool industry. The linear guide itself is divided into two parts: the slide rail and the slider. There are balls or rollers with internal circulation in the slider, and the length of the slide rail can be customized. It is a modular component, and is a standardized and serialized separate product produced by a specialized manufacturer. It can be installed on the machine tool. After wear and tear Can be removed and replaced.
The linear guide can be understood as a kind of rolling guide, which is an infinite rolling cycle of steel balls between the slider and the guide rail, so that the load platform can easily move linearly with high precision along the guide rail, and the friction coefficient is reduced to the usual traditional sliding guide. It can easily achieve high positioning accuracy.
