What Is A Linear Motion Guide

The THK Cross Roller Ring is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Because it has orthogonally arranged cylindrical rollers, it can bear loads in every direction.

The aerospace industry demands high-performance systems in unusual environments. THK's products developed for use in vacuums and other special operating environments are used in manufacturing equipment from spacecraft bodies to spacecraft seat mechanisms.We also provide ina bearing, KWE20-G3-V1, KWE35H-G3-V0, KWE25H-G3-V0, KWE20-G4-V0, KWE15H-G4-V0, KWE20H-G4-V0, etc.
 
What Is A Linear Guide Used For?

Aerospace

The aerospace industry demands high performance systems in unusual environments. THK's products developed for use in vacuums and other special operating environments are used in manufacturing equipment from spacecraft bodies to spacecraft seat mechanisms.

Seat sliding mechanisms
LM Guide Model SR are used in the seat sliding mechanism of small aircraft. Because the floors in aircraft are generally made from sheet metal, measuring errors relating to mounting sections are common, and mounting can be a lengthy ...

Industrial Robots

Robots are used in various industries to position workpieces very quickly and accurately. Some robots have multi-joint assemblies letting them simulate the movements of human arms. These joint sections must have a high swing accuracy and high rigidity ensuring that sudden stops do not put them off-track, THK's unique products are powerful and small enough to meet those demands.

Machine Tools

THK's linear motion systems help provide the guidance that makes this precision and speed possible. All the various parts used in machine tools are made by "mother machines" that produce machine parts themselves. Whether fine and complex or massive and heavy, the manufacturing precision of parts produced by machine tool is increasing at an accelerating pace. 

Machining centers
The leading player among cutting machines is the "machining center." Highly accurate and rigid, Caged Ball LM ...

Manufacturing Industries

Today, semiconductor and LCD panel manufacturing equipment is essential for the production of all kinds of electric and electronic appliances, including PCs, cell phones and flat-panel televisions. Advances in this equipment promote enhancements to PC performance and cell phone functions, and enrich people's lives by reducing the cost of flat panel TV sets. THK's products can meet this kind of high-technology need for fine movement control.

X-ray equipment
Our LM Guides and Cross Roller Rings are used for movement of X-ray receptors. This allows for the X-ray machine to move the ray transmitter and receiver units in any direction and take images from any angle, regardless of the position of the patient. When THK's products are used, the machine's vibrations and noise are also reduced, eliminating patient concerns.

How To Measure The Quality Of THK Linear Guide

MORE PRODUCTS >
There are more and more linear guide manufacturing industries in the market now. The things made by each manufacturer seem to be the same, but if you pay attention to it, you can tell the good or the bad. Now I will introduce a few points to you, which is very simple. It can be distinguished. When you plan to buy a linear guide last year, everyone’s first reaction is to push the slider and try to see if it can slide normally. Of course, everyone knows that as long as the sliding is smooth and there is no interval, this is good.

With the continuous development of society, urban industrialization is also developing rapidly. Of course, the machinery industry is indispensable in industrialized cities. In the machinery industry, most of the high-precision work is completed by relatively high-precision guide rails. So with these changes, the appearance of guide rails has given us a great help. The more guide rails appear on the market, the less we can distinguish its quality. Then we will analyze how to measure the quality of THK linear guide.
THK linear guide type machining process is a very important part. Therefore, it is necessary to pass the quality inspection, otherwise it will affect the component processing effect.
Below, we can analyze the internal structure of the linear guide to see how to measure the quality of the linear guide.
 
Generally speaking, linear guide rails are composed of guide rails, sheaths, collectors, hangers, connectors and other parts, and the expansion section can be configured according to different component requirements. First of all, we have to look at the service life of the guide rail carbon brushes. Generally, this component is a consumable, and the driving distance will affect the maintenance cycle of the equipment.

Secondly, we can look at the quality of the trolley wire shell. At this time, we need to pay attention to the temperature and environment. If the length exceeds 100 meters, we need to consider the expansion of the linear guide. The sheath is composed of engineering plastics with toughness, wear resistance, anti-aging and flame retardant properties, and has a good insulation protection effect on the guide rail to ensure personal safety.

The retainer directly limits the linear guide rail to the position of Zhijiachu, so that it can guide the other fixed sides to extend, thereby providing insulation protection for both ends of the guide rail.

As for how to measure the quality of THK linear guides, these will also be measured by practical experience in life. As long as everyone is careful about these problems, it will not become a problem. we also have HGL15CA hiwin bearing，HGL25CA hiwin bearing，HGL25HA hiwin bearing，HGL30CA hiwin bearing，HGL30HA hiwin bearing, and so on.
