Is the bushing or roller in the sliding bearing? TwentyIs the bush or roller in the plain bearing? How do I search the "sliding bearing" in the Baidu picture, and some of the sliding bearings also have cylindrical roller, which is not cylindrical roller bearings?
Antirust function is used in the grease inside the bearing, need to have antirust effect, antirust agent best can not dissolve in water. Grease should have good adhesion. It can form an oil film in the name of steel. What kind of bearing is good, even if the grease is filled with water, it can also keep it. Mechanical stability. Grease will soften during machining and cause leakage. When an example of vibration is applied, the grease is thrown from the bearing housing into the bearing. If the mechanical stability of the grease is not enough, the grease will always be thrown out of the bearings, which will lead to mechanical disintegration of the soap structure and the use of grease. The oil seal is required to maintain bearings and lubricants to avoid external contamination, regardless of debris or moisture, which can not penetrate the bearings to prevent damage. Proper device maintenance is an important factor in using the longest life of the bearing.
Therefore, it is essential to know the base oil viscosity at the operating temperature. The manufacturer usually specifies the use of some kind of grease, and most of the scale grease can be used in a wide range. The following is a number of important factors in selecting grease: - Mechanical variety - working conditions, such as vibration and axis horizontal or vertical - bearing type and size - temperature - cooling case - work load - sealing effect - speed range of peripheral equipment - machine environment if you want to play to the best condition of bearing must be to work properly, and prevent the high temperature, moist and polluted environment. Lubrication and covering the appropriate plan, and bearing condition monitoring is the key to play the long-life bearing. When the bearing is damaged, it may cause unexpected equipment to stop. Even an hour of downtime, because the bearing in advance, may cause great loss of production. In order to ensure the healthy operation of the equipment, in addition to relying on high-quality bearings, but also pay attention to operating environment, proper installation and regular protection.
At the same time must pay attention to the cleanliness of bearings, bearings selection accuracy and the use of appropriate installation and maintenance tools. Bearings must be protected against contamination and moisture, and must be properly installed and lubricated. The design and arrangement of the state seal bearing and lubricant type and lubrication cycle, bearings, and even specialized Yang are performing similar roles. Mixed oils do not mix incompatible oils. If two incompatible oils are mixed, the consistency is usually soft and may eventually be destroyed by the loss of grease. If you do not know what kind of grease the bearings should have used, then remove the old grease from the inside and outside of the bearings before you add grease. According to the classification of oil temperature and identify the premise: the oil can according to their allowable working temperature to classification, oil viscosity and smooth to be affected by the operating temperature, bearing the operation at certain temperature will need to have accurate choice consistency and good lubrication result at the same temperature grease. Oils are made from a range of work temperatures that can be identified as low temperature (LT), medium temperature (MT), and high temperature (HT) oils. At the same time, there is a kind of grease called EP (extrusion resistance) or EM (extrusion and increase molybdenum disulfide), plus additives to enhance the strength of the lubricating film. If you choose the oil grease selection fault bearing damage to all defenses in vain, choose a grease base oil viscosity at the temperature when it can supply sufficient lubrication effect is very important, important is the viscosity affected by the temperature, with the temperature rise and fall, when the temperature is decreased when it is picked up.
