As a commonly used motion system in various machinery, it is a very important component, so it needs to be maintained frequently during the daily use period, otherwise it will affect the efficiency of the machine. Next, I will tell you Share the maintenance methods of metal linear bearings and plastic linear bearings to help you normal production in the process of using machinery.
As we all know, anti-corrosion oil is often injected into the metal linear bearing. If grease is used for lubrication, it is necessary to use kerosene or an organic solvent to remove the anti-corrosion oil stains inside. Add new grease inside. During the lubrication process, if the anti-corrosion oil stain is not removed, the user can use other grades of lubricating oil according to the temperature change. When adding lubrication, it can be supplied by the oil supply pipe or from the oil hole of the outer bearing housing part. Because the sealing ring will scrape the lubricating oil away, it is not suitable for the five-hole bearing with oil lubrication. Parts.
Since the sliding film inside the plastic linear bearing is made of self-use and plastic, you do not need to provide additional lubricating oil and maintenance during the process of using the plastic linear bearing, and because it also carries a drain groove inside, It can perform self-cleaning, and the dust from the outside world can be automatically discharged during the movement. Only when the sliding friction of the plastic linear bearing is worn, its lubricating effect and cleaning effect will be lost. At this time, only the inside The sliding film can be replaced, and the maintenance is quite simple.
The linear bearing adjustment type will have some elastic deformation at the cutting opening. At this time, the matching clearance should be installed in the bearing to measure the existence of the game. The adjustment direction of the linear bearing can be adjusted to be perpendicular to the direction of the bearing groove to ensure that It's even. The structural feature of linear bearing is that it can't do rotating motion, and it also requires good guiding performance. Therefore, the general bearing is based on two shafts and four sets of bearings or two shafts and two sets of extended bearings. Use a combination. . The two shafts must be kept parallel during the installation process. After the entire assembly is installed, the user can push and pull by hand. At this time, feel flexible and unimpeded to install the rotating mechanism. The rotating mechanism must be able to overcome the resistance caused by the friction of the bearing.
After the linear motion bearing series is decomposed into various parts, it may cause foreign matter to enter, or the assembly accuracy of each part is not enough to cause adverse effects, so it cannot be disassembled at will. The falling or knocking of the linear bushing may cause damage to the parts, so when the product is impacted, the function may be damaged.
The quality of our company's linear bearings, ball screws, roller guides, linear guides, bearings, guides and other products are guaranteed, and they are trusted by customers. Welcome to contact.
