There are many kinds of precision and grades of THK agent guide rails, and the prices are also different. When we choose THK agent guide rails, we can choose according to the size of the load, the direction of the load, the size of the impact and vibration, etc. Now basically all mechanical products need to use linear guide rails, and the function of linear guide rails is to run, so linear guide rails are necessary in the entire industry, but now it is equally important that THK linear guide rails are a small part for supporting linear guide rails. The quality of this part will directly affect the work of the machine, so special attention should be paid when choosing linear guide rails to avoid unnecessary losses. The same is true in use. What should be paid attention to when THK linear slide rails are driven off the rails?
If it is a ball cage THK agent guide rail slider product, the steel ball will not fall off even if the THK slider is removed. For other models, there are two cases of ball holding fixing function and no ball holding fixing function. For products without ball holding function, when the THK agent linear guide rail slider is removed, the steel ball falls off, which can be solved by using false rails and plugs.
Different models of THK linear guide products show different allowable loads in different load directions. For radial guides, pay attention to the radial and anti-radial rotor load values. It is recommended to use four-way equal-load guides. Also, pay attention to the installation strength of the bolts. If the load is heavy, it is recommended to halve the spacing of the mounting holes. If it is a wall-mounted installation, the installation reference is required to prevent the bolts from being subjected to shear loads.
Can I use THK linear guides on rough surfaces? The requirements for the mounting surface flatness of THK linear guides and THK slider models are shown in the THK product catalogue. In comparison. What do you need to pay attention to when using the LM guide alone? If the LM guide alone is used, the load distribution in the local area will be larger when subjected to torque load, thus shortening the service life. When the THK linear guide has a deflected load, the ball screw may be affected by radial force and cause damage. Ideally, two LM tracks are used in parallel. However, due to space constraints, you need to use the guide. You can choose wide SHW or HRW; or you can increase the number of sliders to withstand torque.
1. The size of the load
Rolling linear guides of different specifications have different load-bearing capacity and can be selected according to the load-bearing size. In order to make each pair of linear rolling guides have a relatively ideal service life, the rated life and rated hourly life can be calculated according to the approximate formula provided by the selected manufacturer, so as to give a reasonable repair and replacement cycle.
2. Preloaded options
According to the shock, vibration and accuracy requirements of the design structure, the appropriate preload value is selected.
3. The direction of the force
Because there are usually four rows of circular raceways on the slider and the guide rail of the rolling linear guide pair, it can bear the load and turning moment in four directions. The bearing capacity of the guide rail increases with the increase of the center distance of the raceway.
Step 4 Save costs
The machine itself is not high, so we can choose a general guide rail, which can reduce costs.
