Master the correct method of installing the THK Linear Motion Guide to improve the service life and accuracy of the guide. Next, let's take a look at the installation of the THK Linear Motion Guide. Here are some answers.
Here is the content list:
Installation method using an installation reference surface.
Installation of THK Linear Motion Guide on the driven side.
First, use the assembly screws to fix the bottom reference surface of the THK Linear Motion Guide to the bottom assembly surface of the bed. And then use a vise to press the side reference surface of the slide rail against the side assembly surface of the bed to determine the position of the slide rail. Finally use torque to tighten the fixing screws with a spanner and a certain torque to press the bottom reference surface of the slide rail against the assembly surface of the bottom of the bed.
Straight-line block method
Place the linear gauge between the two THK Linear Motion Guides, and use a micrometer to calibrate the linear gauge so that it is parallel to the side reference surface of the reference side slide rail. Then calibrate the driven side slide rail according to the linear block gauge, start calibration from one end of the driven rail, and tighten the assembly screws with a specific torque in sequence.
Mobile platform law
Fix the two sliders on the reference side on a measurement platform, and install only one slider on the driven side. The slide rail and the sliding block are not fixed to the bed and the platform, and the micrometer scale attached to the top surface of the driven side sliding block is used. Measure the side reference surface of the driven side slider, start calibration from one end of the driven THK Linear Motion Guide, and tighten the assembly screws with a specific torque in sequence.
Imitate the reference side slide method
Fix one of the two sliders of the reference side THK Linear Motion Guide and the driven side rail to the platform. Then the slide rail on the driven side and the other slide rail are approximately respectively fixed to the bed and the platform, and the platform is moved based on the reference side slide rail. Starting from one end of the slide rail, while confirming the rolling resistance of the linear guide on the driven side, tighten the assembly screws with a specific torque in sequence.
Special tool method
Using professional tools to install the THK Linear Motion Guide means to use professional tools to determine the position of the driven side slide rail, and to tighten the assembly screws with a specific torque in sequence.

The lock nut for THK Ball Screw can fasten the screw shaft and bear very easily and accurately. The use of an anti-loosening mechanism composed of a hexagon socket head fixing screw and a mounting piece can prevent the locking nut from loosening and ensure a firm connection. Next, let's take a look at the accuracy and manufacturing method of the THK Ball Screw. Here are some answers.
Here is the content list:
The accuracy of THK Ball Screw.
The manufacturing method of THK Ball Screw.
According to GB classification, THK Ball Screws are classified into P and T, namely transmission and positioning. The accuracy grades are 1, 2, 3, 4..Foreign THK Ball Screw products generally do not distinguish between transmission or positioning, and all use C0~C10 or specific numerical representation. Generally speaking, general-purpose machinery of ordinary numerical control machinery choose C7 or below, high-precision numerical control machinery choose C5 (±0.018) above C3 (±0.008) below, optical or detection machinery choose C3 above. In particular, it is important to note that accuracy and price are highly correlated, and the concept of accuracy is combination and maintenance. That is to say, the lead error of the screw cannot explain the error of the whole set of screws, and the factory precision cannot mean that this accuracy is maintained within the rated service life. This is a reliability issue, which is related to the manufacturer's production process.
There are two main manufacturing methods of THK Ball Screw: rolling and grinding. The former is also called rolling manufacturing or transformation, and is generally denoted by F. The latter is also called grinding and manufacturing, and is generally represented by G. Due to the difference in technology, the two can achieve different levels of accuracy. At present, the highest accuracy that can be achieved by the rolling method is the C5 level. Grinding can produce products with higher precision. However, please note that there is no reverse inevitability between the two manufacturing methods and accuracy and performance. In other words, if the accuracy you choose is C7, it has nothing to do with how it was made.
I have encountered many professional sales staff of manufacturers who may not know the detailed difference between the two. So a few more words: rolling belongs to batch manufacturing, and grinding belongs to precision manufacturing. The production efficiency of the former is much higher than that of the latter, but the cost of manufacturing equipment of the former is also much higher than that of the latter. In other words, the entry barrier for ground THK Ball Screw is low, and the entry barrier for rolling production is higher. Manufacturers that can produce rolled screws generally can also produce ground screws, while manufacturers that can produce ground screws may not necessarily be able to produce rolled screws. Therefore, if the THK Ball Screw with the same precision can buy rolled products, don't buy grinding products. The reason is simple: cheap. Another point is that rolling and grinding only refers to the screw, and the nut is all manufactured by grinding.

IKO C-Lube Linear Way ML is a product that has a built-in lubrication component C-Lube self-lubricating tube on the slider of the small linear guide series, which can achieve long-term maintenance-free products. Next, let us know about the information on IKO C-Lube Linear Way ML. Here are some answers.
Here is the content list:
IKO C-Lube Linear Way ML has different lengths for the sliders of the same cross-sectional size. There are three types: short, standard, and high-rigidity extended. Users can choose the appropriate type according to the application. In addition, IKO C-Lube Linear Way ML has products that can be freely combined. The size of the slider and the slide rail is managed separately, and each can be added or replaced freely. The C-Lube self-lubricating tube does not directly contact the slide rail, so it does not increase the sliding resistance and achieves smooth and light sliding. The lubricating oil in the C-Lube self-lubricating pipe maintains long-term lubrication performance, which can reduce labor costs required for tedious lubrication management, and can be maintenance-free for 5 years or 20,000km.
First, the simple structure of IKO C-Lube Linear Way ML can achieve an extremely small size. IKO C-Lube Linear Way ML is an ultra-small linear guide device created by the simple structure of the 2-row 4-point contact method and the original "Small-Sizing" technology. And IKO C-Lube Linear Way ML is a built-in C-Lube self-lubricating tube on the small series linear guide, so the external dimensions remain unchanged, small, and lightweight.
Second, IKO C-Lube Linear Way ML is a rich product series that meets diverse needs. IKO C-Lube Linear Way ML has two types of sliders: standard type and wide type suitable for single-row slide rails. The length of the slider has four different types under the same cross-sectional size. In addition, the slide rail also has standard specifications and internal thread specifications with threaded processing. Users can choose the most suitable product according to the specifications of the machine and device.
Third, the IKO C-Lube Linear Way ML has a ball fixed type that is easy to assemble. The ball fixed slide block is equipped with a steel ball retainer, so even if the slide block is removed from the slide rail of the IKO C-Lube Linear Way ML, the steel ball will not fall off, the structure is safe and reliable, and it is easier to install on the machine.
Fourth, the IKO C-Lube Linear Way ML is made of stainless steel with excellent corrosion resistance. Therefore, IKO C-Lube Linear Way ML is suitable for use in places where grease is hated and anti-rust oil needs to be controlled, as well as in clean rooms.

Among the linear transmission components of mechanical equipment, we commonly use THK Caged Ball LM Guide. In addition, there is also a Caged Roller LM Guide. What is the difference between THK Caged Ball LM Guide and Caged Roller LM Guide? I Interested friends can follow me to learn about the difference between THK Caged Ball LM Guide and Caged Roller LM Guide. Here are some answers.
Here is the content list:
The main difference between THK Caged Ball LM Guide and Caged Roller LM Guide is the bearing capacity.
The biggest difference between Caged Roller LM Guide and THK Caged Ball LM Guide is that they have different rolling methods.
Caged Roller LM Guide uses cylindrical roller bearings in the slider, which has a large total contact area and can bear a large load. The THK Caged Ball LM Guide uses ball roller bearings in the slider, which can bear a relatively small load. The advantage is because the total contact area is small, and correspondingly, its frictional resistance is also smaller. In general, THK Caged Ball LM Guide is faster and less rigid, while Caged Roller LM Guide is slower, but its rigidity is better.
The most direct difference between THK Caged Ball LM Guide and Caged Roller LM Guide is the medium they roll. THK Caged Ball LM Guide uses rigid beads, and Caged Roller LM Guide uses steel columns. Therefore, the rolling elements of the THK Caged Ball LM Guide are balls, and the contact with the slideway is point contact, which is divided into two-point and four-point contact. Of course, the more contact points, the better the rigidity, the higher the manufacturing accuracy, and the higher the cost.
The support body of the Caged Roller LM Guide is a roller, and the contact with the slide is line contact. Compared with the ball type, it is characterized by higher rigidity and greater bearing capacity, but there is a problem that its stroke is limited, unlike most Ball-type, the stroke can be spliced very long and the length is not limited. Relatively speaking, THK Caged Ball LM Guide will have lower cost, faster speed, and longer splicing. The roller type has the greater bearing capacity and better rigidity under the same volume.
