INA spherical roller bearing lubrication quality importance to working conditions - bearing knowledge

As one of the import bearings, INA bearing in operation process, the usual how modest for bearing lubrication bearings in the maintenance and maintenance is also one of the important link that nots allow to ignore. Oil bath smooth, smooth is common in the bearing is suitable for low and medium speed bearing is smooth. Bearing a partial immersion in the slot, smooth oil by the spherical roller bearing parts of rotation, and then flow back to the oil level of oil tank should be slightly lower than the lowest in the middle of the roller. Drip smooth smooth oil bearing components, suitable for the need to ration the drops of oil every 3 - individually A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased. Walks in oil pump will be filtered oil to the INA bearing parts, through the bearing smooth oil filter cooling after use. Because circulating oil can take away heat, must make bearing cooling, therefore method suitable for spherical roller bearing components of high speed. In dry contraction by the sprayer and smooth air oil mixed oil mist, radial bearings, can effectively make the bearing cooling airflow and can avoid intrusion. This method is suitable for high speed and low temperature bearing parts is smooth. With oil pump nozzle shot into the bearing, the oil in the low pressure into the bearing of the bearing at the other end into the oil in the tank. When bearing at high speed, rolling body and maintain frame to match the rotation of the high speed air cause air flow around, it is hard to smooth the oil to the bearings in individual smooth way, then must smooth oil spray with low radiation to bearing, the status of the nozzle should be placed in the middle of the inner ring and maintain frame between. 1) Compared with the roller bearing, ball bearing has high limit speed, so the priority is at a high speed ball bearing. 2) In diameter under the same conditions, the smaller the diameter of the roller is small, the lighter when working roller bearings on their path and the smaller the centrifugal inertia force, as a result, more suitable for working under higher rotate speed. In high speed, appropriate chooses super light, light, and light series of bearings. Heavy and heavy series of spherical roller bearing, only for the occasions of low speed and heavy loading. If use a light series of INA bearings and bearing capacity can not meet the requirements, can consider to use wide range of bearings, or the two light series of bearing and used together. 3) Cage has enormous influence on the material and structure of bearing rotating speed. Entities cage than punching cage allows for a higher speed. 4) Bearing the access speed is very low. When work high speed, if the axial load is not very big, can use wheel angular contact ball bearing under pure axial force. 5) If the work speed is slightly more than the limit specified in the sample, can be used to improve tolerance grade of spherical roller bearing, or more appropriately bearing radial clearance, choose circulation lubrication or oil mist lubrication, measures such as strengthen the cooling of the circulating oil to improve the performance of high speed on the bearing. If the working speed exceed limit rotational speed is more, should choose a special high speed rolling bearing. Under the general speed, speed affects the choice of the type is not what happens, only if the speed is high, just can have more significant effect. INA bearings samples on the limit speed of various types, various size bearing nlim values. This speed is refers to the load is not too big, P≤0。 1 C, C as the basic dynamic load rating) Normal, cooling conditions, and the level of zero tolerance when bearing the maximum allowable speed. But, because of the limit speed is mainly restricted by working temperature rise, therefore, cannot think limit rotational speed is a absolutely not in the samples beyond boundaries. If the spherical roller bearing working speed exceed limit speed, can adopt the following article 5 of the measures are put forward.
