Analysis of IKO import bearing grease deterioration reasons and measures - bearing knowledge

Use within IKO import bearing grease must have antirust effect, rust inhibitor is best can not dissolve in water. Grease shall have good adhesion, and can form a layer of oil film on the surface of steel, oil in machining will become soft, cause leakage. During normal operation, oil will from IKO bearing to IKO import bearings. If the mechanical stability of the oil is insufficient, operation process, the structure of the soap grease causes mechanical disruption of oil was damage, and thus lose lubrication, if the wrong choice grease all import bearings IKO prevention measures is useless, choose a grease, its oil viscosity in working temperature is it is important to be able to provide adequate lubrication effect, viscosity is mainly affected by temperature, it with the temperature rising and falling, is that it increased when the temperature decreases. Therefore, you must know when working temperature of the oil viscosity. Machinery manufacturers are usually specified use some grease, however most of the standard grease applicable range is very wide. In the process of using IKO import bearings, grease is critical. If bad grease, used, don't effect not only, also can damage IKO import bearings. (1) take oil flow observation two cups, one of them need to be checked out of the lubricating oil, empty on the desktop, the other will leave the measuring cup with lubricating oil for high 30 - desktop 40 cm and tilt, let oil flow slowly to the empty cup, to observe the flow situation, good quality lubricant oil flow should be long and thin, uniform, continuous, if appear oil flow fast and slow, and sometimes has a large flow, the said lubricating oil has deteriorated. (2) hand twist to lubricating oil lay between the thumb and index finger grinding, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced. (3) illumination method on a clear day, use a screwdriver to lubricating oil lifted, and horizontal Angle of 45 degrees. Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, can continue to function, if excessive wear debris, lubricating oil should be changed. (4) oil droplets trace method in a clean white filter paper, number of oil drops on the filter paper, after waiting for lubricating oil leakage, if the surface is black powder, touch resistance acerbity feeling, is the lubricant inside has many impurities, good oil powder, with the hand feels dry, smooth, and yellow.
