2025-02-14

The most significant feature of the THK SRG series linear guide slider is that it is a roller series. Because roller series guide sliders have line contact with the guide rail, compared to ball guides, the contact area is larger, resulting in a stronger load carrying capacity. The following is a detailed introduction:
 
Model Classification
 
- Classified by size: SRG15 series, SRG20 series, SRG25 series, SRG30 series, SRG35 series, SRG45 series, SRG55 series, SRG65 series, SRG85 series, SRG100 series, etc.
 
- Classified by structural features: Includes standard types such as SRG-C type; extended types such as SRG-LC type and SRG-SLC type; narrow types such as SRG-R type; narrow extended types such as SRG-LR type and SRG-SLR type; top-mounted types such as SRG-A type and extended LA type, etc.

                

              
 
Product Features
 
- High Rigidity: Uses high-rigidity rollers; the roller length is more than 1.5 times the roller diameter. Compared to ball-type guides, the contact area between the roller and the guide rail is larger, allowing it to withstand higher loads.
 
- Four-Directional Equal Load: Each roller row is arranged at a 45° contact angle, giving the LM slider the same rated load in the radial, anti-radial, and lateral directions. It has high rigidity in all directions and can resist forces from different directions.
 
- Smooth Movement: The roller retainer evenly spaces and circulates the rollers, preventing roller offset when the slider reaches the load zone, minimizing fluctuations in rolling resistance.
 
- Long-Term Maintenance-Free: The roller retainer eliminates friction between rollers and improves grease retention, reducing maintenance costs and downtime.
 
- Standard Size Design: The size is based on the all-steel ball LM rolling guide HSR type, offering interchangeability and universality, facilitating system design and component replacement.
 
- Abundant Accessories: End seals, internal seals, side seals, multi-layer contact scrapers LaCS, dust covers, side scrapers, GC hole covers, and other components are available.
 
Application Scenarios
 
Due to its high rigidity and four-directional equal load characteristics, it is suitable for large-scale machinery or heavy industrial applications with high load capacity requirements, such as large machine tools, heavy processing equipment, and industrial robots. It can also be used in automated production lines and precision measurement equipment that require high motion accuracy and stability.

Linear guide rail - stainless steel guide rail

sj2025-01-08

Linear guide rail - stainless steel guide rail

Due to different working environments, there are different requirements for linear guides. Let's talk about stainless steel linear guides. Although not widely used, common brands such as THK, HTPM, and HIWIN all offer stainless steel linear guides, but only a few models are made of stainless steel. There are many short videos online introducing linear guides. These videos are short and fast-paced, requiring multiple viewings to fully understand. While they may seem informative at first glance, upon closer examination, they lack significant in-depth knowledge (personal opinion). Let's discuss the advantages and disadvantages of stainless steel guides. The advantages of stainless steel guides mainly include: 1. Strong corrosion resistance: They maintain stable performance in humid and corrosive environments, resisting oxidation, reduction, and acid-base erosion. 2. Good wear resistance: The surface is specially treated, providing high wear resistance, suitable for high-load, high-speed operation, and extending the service life. 3. High precision and stability: They enable precise sliding and positioning, improving production efficiency and product quality. 4. Strong load-carrying capacity: They can withstand significant loads and impact forces, meeting the needs of various applications. 5. Wide range of applications: They are widely used in chemical, marine engineering, food processing, CNC machine tools, automated equipment, and industrial robots. However, there are also some drawbacks: 1. Higher cost and price: The high cost of stainless steel leads to relatively expensive guides. 2. Heavier weight: The high density and weight of stainless steel increase overall equipment weight and cost. 3. Difficult to process: The high hardness and toughness of stainless steel require special processing techniques and equipment, increasing processing difficulty and cost. In summary, stainless steel guides excel in corrosion resistance, wear resistance, precision, and stability, but are relatively costly and difficult to process. Selection should be based on specific application scenarios and requirements.

Linear guide rail replacement and repair case

Linear guide rail replacement and repair case

The following is a case study of replacing and repairing a linear guide rail: Customer feedback: "The equipment suddenly stopped moving left and right, so it needs repair." Therefore, we went to the site to replace the linear guide rail installed on the equipment. On-site confirmation: A device for processing profiles is installed above the linear guide rail. This device moves left and right using the linear guide rail to process the profiles. However, the guide rail on site could no longer move left and right, preventing it from working. It was visually apparent that the linear guide rail was damaged. When the equipment on the guide rail was lifted with a crowbar and the slider was removed, it was found to be damaged. Due to severe rusting at the mounting points of the slider and rail, it was difficult to remove the slider when disassembling it, which may have caused the damage to the linear guide rail. When we tried moving it again after replacing it with a new slider, the movement was still very poor. It is estimated that simply replacing the slider would not only cause it to be damaged again, but may also damage the rail and rack. Therefore, we informed the customer of the current condition of the equipment, the repair method and the quotation, and persuaded the customer to carry out further repairs. Repair process The equipment was lifted with a crowbar, and wooden blocks were placed under the workbench to prevent the equipment above from falling, and then the slider was removed. When trying to remove the slider, it was quite difficult to move it due to severe rust on the rail. Since the slider could not be removed smoothly, we first removed the rust using sandpaper and rust remover. (The rust on the rail made it difficult to move the slider; if the slider was forcibly moved, it could be damaged.) After the repair and test run, the workbench of the profile processing equipment ran smoothly. Suggestions on how to prevent recurrence of faults Regular inspection of transmission parts is very important to prevent unexpected damage. As a preventive measure, it is recommended to lubricate the guide rail regularly. If not dealt with in time, this kind of rust will occur, which may lead to equipment failure. (Construction site: Gunma Prefecture, Japan) The above is the main content of the repair report. This is a very common after-sales service scenario. Therefore, the questions are: 1. The report believes that the main cause of the failure is rust on the guide rail. Do you agree with this reason? 2. The corresponding measures in the report are: replacing the slider and removing rust from the rail. Is this OK? If you have better suggestions, please leave your comments and suggestions.
