Select the bearing selection of experts: deep groove ball bearing grease on the significance of stability

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn to choose deep groove ball bearing grease on the significance of stability. 1, rust resistance, rust inhibitor is best can not soluble in water, has the good adhesion, can form a layer of oil film on the surface of steel. 2, mechanical stability, if the mechanical stability of the oil is not enough, in the process of operation, the structure of the soap grease causes mechanical disruption of oil by damage, thereby losing lubrication. 3, oil seal oil seal is necessary to protect deep groove ball bearings and lubricant from contamination from barrier, HRB bearing operation process, regardless of debris or moisture can penetrate bearings, in case of causing damage to it. 4, oil mixture of mixed oil don't put the incompatible, if two incompatible oil mixture, usually will soften its consistency, might end up bearing damage caused by oil easy to loss. 5, the classification of grease lubrication grease consistency and ability is affected by temperature, at a certain temperature operating HRB bearings must choose under the same temperature has the correct consistency and good lubrication effect of oils and fats. In general, in the deep groove ball bearing grease filling amount, always exceeds the actual requirements, directly involved in the lubrication of the rack and HRB bearing cover of the cavity, and forms an outline in rolling around in vitro. In this process, due to excess grease resistance, bearing temperature rise quickly. Although most redundant grease at the beginning of the operation is being squeezed out, and squeezed in the raceway attachment grease could still be turning into the groove between roller. Most of these in the early stages of the bearing grease quickly ( Less than a minute) Is being squeezed out of raceway and the accumulation in the grease in the bearing rotation of systemic circulation at the same time, have a small amount of discharge. When the bearing temperature continues to rise, until all redundant grease were out, may be called the grease running-in stage, according to the structure of the bearing grease factors such as quality, filling quantity, this paragraph of time may last ten minutes, or even a few hours. Bearing grease is completely after discharge, the rest of the rest of the small amount of grease in the rolling element and raceway, keep contact with each other, cadastral wedge formed by a thin film of grease, so as to enter the bearing of the normal phase. The temperature decrease and balance. That is to say, the long-term lubrication, mainly rely on the film of grease. In addition, in the process of long-term operation of HRB bearing, rolling element and raceway profile near detachments and keep on the shelf to atrophy and grease base oil, flow into the race, between supplement to lubrication also to have certain effect. Different HRB bearing grease in the bearing form outline to traffic is not the same, must form the contour comparison is, running-in time is short, in the long-term operation of HRB bearing temperature is low, and smooth, this is a kind of ideal grease, so is especially important for into the canal of grease. Some so-called vortex type grease is not, is not easy to form the outline, even form the contour is easy to collapse, then roll back to the redundant grease in the tiny repeatedly chronically stirred by strong column, bearing torque is big, high temperature, and uneven, also may produce noise, grease also easy metamorphism and erosion.
