Linear guide bearings are mechanical components used in linear reciprocating motion. Their rated load is higher than that of linear bearings. Their structure can withstand high-load environments and achieve high-precision linear motion.
The self lubricating bearing guide system can provide sufficient and appropriate lubricating oil to the guide groove through a high-oil-content oil storage block and an optimized oil film forming design to lubricate the equipment, thereby reducing friction and wear, improving overall work efficiency and life, and achieving environmental protection, extending the lubrication cycle, and saving resources.
1.The Necessity of Self Lubricating Bearing
The purpose of adding lubricant to the linear bearing is to prevent metal contact between the track surface and the rolling element inside the linear guide, reduce friction and wear, and thus prevent heating and sintering. When a sufficient oil film is formed on the contact surface between the track surface and the rolling element, it also has the effect of reducing the contact stress caused by the load. Ensuring that the oil film is fully formed is very important to ensure the reliability of the linear guide.
2. Working Principle
The normal operation of the self lubricating bearing module mainly depends on its internal lubricating material and design, so that the lubricant can be automatically released during movement, thereby reducing friction and wear. The specific working process is as follows:
- The self-lubricating module usually uses composite materials containing lubricants, which are embedded in the structure of the guide rail or slider during the manufacturing process.
- When the guide rail and the slider start to move relative to each other, friction will be generated on the contact surface.
- During the friction process, the lubricating material will gradually release the lubricant to form a thin lubricating film. This lubricating film can effectively reduce friction and wear and protect the surface of the guide rail and the slider.
- The design of the self lubricating bearing allows the lubricant to be continuously released for a long time, ensuring that the guide rail is always lubricated during operation. Under high temperature or high load conditions, the release rate of the lubricant may be accelerated, thereby providing better lubrication and ensuring the stability and reliability of the guide rail.
3. Replenishment Interval of Self Lubricating Bearing
Even high-quality grease will age with the running time, so it must be properly replenished (generally, the grease sealed in the factory state will be exhausted after running for about 600km). The grease replenishment interval varies depending on the conditions, generally once every 6 months. For machinery with long-distance reciprocating motion, it is recommended to add grease every 3 months. The linear guide bearing with built-in self lubricating module achieves long-term maintenance-free, eliminating the indispensable oil supply device and refueling time for the linear guide, which can greatly reduce maintenance costs.
Summary
The self lubricating bearing module is an efficient, low-maintenance linear motion solution that can provide reliable lubrication in various harsh environments. Through the reasonable selection of lubricating materials and design structures, the self-lubricating module can effectively reduce friction and wear and extend the service life of the equipment. With the continuous advancement of technology, the application areas of self-lubricating modules will be further expanded, providing better solutions for all walks of life.
