KOYO linear bearing the basic performance remaining when maintenance is required

1. Trunnion avoid direct contact with bearing friction compatibility attack adhesion and constitute a border smooth performance. Affect the friction pair friction compatibility of data element is: ( 1) As deputy information on metallurgical alloy difficulty levels. （ 2) Data and affinity to smooth agent. （ 3) As a deputy data in the condition of no smooth friction factor. （ 4) The microstructure of materials. （ 5) Thermal conductivity of materials. （ 6) Data can appearance size and characteristics of the oxide film. 2. Embedding information allows smooth agent in foreign pliers and avoid scratch or hard particle ( And) Abrasive wear ability. For metallic materials with low hardness and elastic modulus, embedding, and nonmetallic materials are not necessarily, carbon graphite, for example, low elastic modulus, but the embedded sex is bad. KOYO bearing usually use soft material and hard material forming friction, ordinary do bearing shell with soft materials. 3. In the diameter of axle and bearing bush of the running-in process, reduce the diameter of axle and bearing shell processing error, alignment error, surface roughness parameter values, make contact with average, thereby reducing the friction and wear rate. 4. Friction compliance data on the surface of sliding friction appearance initial elastic-plastic deformation compensation to match the performance of the poor and shaft deflection. Low modulus of elasticity of material compliance is good. 5. Abrasion resistance into vice materials can resist abrasion. Under the condition of the rules of wear, wear rate or amount of wear, wear the reciprocal of abrasion resistance. 6. The fatigue resistance under cyclic load data can resist fatigue damage. The use of temperature, the strength of the bearing shell material, hardness, resistance to impact strength and organization average opposite tiredness is very important. Running-in, the embedded data, usually poor fatigue resistance. 7. Corrosion resistant materials can resist corrosion. Smooth oil used in atmosphere will gradually oxidation, produce acidic substances, and in most smooth oil also contains extreme pressure additives, KOYO bearing all corrosion data, therefore, KOYO bearing information requirements have corrosion resistance. 8. Cavitation resistance motion state, the related to the liquid when the bubble in liquid solid appearance full break, a part of the impact high pressure or high temperature part, will cause cavitation and wear. Data against cavitation and wear can be referred to as cavitation resistance. Usually, the copper lead alloy, KOYO bearing alloy and aluminium zinc silicon alloy cavitation resistance is better. 9. Accept unidirectional compressive strength load without being crushed or size does not change. Discriminant standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, KOYO bearings shall not to use, must change. 1) Linear bearing fracture and defect of the parts. 2) The raceway surface material on the surface of the rolling strip. Bearing fault identification method without disassembly check, can identify or predict the linear bearing any operation problem, consumption rate of progress and economy is very important. The major identification method is as follows: 1) Through voice stop identification through a voice stopped to identify the demand has a rich experience. Must arrive after vigorous exercise can recognize voice bearing with the KOYO bearing. Therefore, we should try to stop by the work. With listening gear or listening bar on the shell can be clear to hear the sound of the bearing. 2) After work stop to recognize the way to compare identification method, the temperature is limited to use in running condition doesn't change. Therefore, it is necessary to stop the continuous temperature records. Not only will the present problem, temperature rise, will also present irregular change. 3) After smooth agent state of stop identification for smooth agent sample analysis, through its purity level can be mixed with foreign matter or metal powder, etc. Stop judging. The way to can't close to see KOYO bearings or large bearings are particularly effective.
