Product Description

The rail system consists of a combination of rails and sliders. Guide rails are also known as linear guides, slide rails, linear guides and linear slides. The slider transforms the motion from a curve to a straight line. The linear guide slider system is known in the mainland. Taiwan is often referred to as linear guides and linear slides.

It is used to support and guide moving parts and perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides and fluid friction guides.

Products Features

Due to the strict control of production and manufacturing precision, the size of the linear guide slider system can be maintained within a certain level, and the slider has a retainer design to prevent the steel balls from falling off. Therefore, some series of precisions are interchangeable, and customers can Order rails or sliders and store rails and sliders separately to reduce storage space.

High rigidity in all directions
The four rows of circular grooves match the 45 degree contact angle, such as four rows of steel balls, so that the steel balls reach the ideal two-point contact structure and can withstand the load of up, down, left and right. The correct direction; if necessary, it can apply a preload to increase rigidity.

Prodcut types and details of Linear guide rail and block bearing:

Ball Rail Systems
Ball Rail Systems from Rexroth are ball-bearing linear guides. They are available in eight common sizes. Our customers use them in machine tools, industrial robots and various special machines.

Roller Rail Systems
Roller Rail Systems from Rexroth are compact, roller-bearing linear guides with incredibly high load-bearing capacity and extreme rigidity.
They are used successfully in many areas in sizes 25 to 125, for example in machine tools, print and paper machinery, injection molding machines, industrial robots as well as presses and heavy-duty machinery.

Miniature Ball Rail Systems
These products are used wherever extremely small ball-bearing linear guides with high load capacity are needed, for example in medical technology and the semiconductor industry.

Principles of use

The rail slider system is one of the core components of precision parts equipment. In order to ensure the machine has high machining accuracy, it is required to have high guiding precision and good motion stability. If used improperly, it will not achieve the expected performance, and it is easy to damage the rail slider system and related equipment. During the operation of the equipment, due to the large amount of corrosive dust and smoke generated during processing, the smoke and dust are deposited on the surface of the guide rail and the linear shaft for a long time, which has a great influence on the processing precision of the equipment. An etch point is formed on the surface of the linear axis of the guide rail to shorten the service life of the device. In order to make the machine work stably and ensure the processing quality of the product, we must conscientiously do the daily maintenance of the guide rail slider system and the linear shaft.Therefore, the following should be noted when using the rail slider system:

Prevent corrosion

When taking the linear guide directly, wash off the sweat from your hands and apply high quality mineral oil before handling. Pay special attention to rust prevention during the rainy season and summer.

Keep the installation environment clean

Keeping the linear guide and its surroundings even if the tiny dust that is invisible to the naked eye enters the guide rail, it will increase the wear, vibration and noise of the guide rail.

Should be carefully installed

The linear guides should be used carefully and carefully during the installation process. Strong stamping is not allowed. It is not allowed to hit the rail directly with a hammer. It is not allowed to transfer pressure through rolling elements.

Should use the appropriate installation tool
Linear guides use special tools and appropriate and precise installation tools, and try to avoid the use of fabrics and staple fibers.


Guide rail slider system is mainly used in automation machinery, spraying equipment, CNC machine tools, machining centers, electronics, automation machinery, textile machinery, automobiles, medical equipment, printing machinery, packaging machinery, woodworking machinery, mold opening and many other fields.
