Of course, if the working speed of the imported bearing is very low and needs to work in a polluted and humid environment, fill the SKF bearing seat with grease.
The standard products provided are more than 20000 kinds of bearings. In addition to rolling bearings, the group also manufactures linear bearings, sliding bearings, bearing housings, ball and roller lead screws, textile machinery parts, retaining rings, machine tools and various precision machinery parts.
With extensive experience in the above fields, we have the Skf Bearing Operation indispensable knowledge and expertise to develop, manufacture and apply various advanced engineering products. The smaller ones are micro bearings weighing only 0.003 g and giant bearings weighing 34 tons each.
In addition, a series of bearing maintenance tools, grease and Skf Bearing Operation bearing monitoring instruments (bearing heater, puller, etc.) are also provided to enable bearing users to obtain higher benefits and achieve worry free operation.
Bearings are precision components, SKF bearings and grease Skf Bearing Operation contamination, will not be able to run. In addition, among all bearings that have been sealed with grease and maintenance free, at least 14% of the pollution
is significantly caused by the use of bearings only in a small part of the early failure of all bearings. The bearing has excellent manufacturing and design capabilities and can provide sealing solutions for various harsh working conditions.
The chemical reaction between lubricating grease and oxygen in the air produces acidic substances. Firstly, it consumes the antioxidant additives in the grease. However, to a certain extent, the generated organic acids will corrode the metal components and destroy the structure of the grease,
reduce its dropping point, increase the viscosity of base oil and deteriorate its fluidity. A large number of tests show that the higher the temperature, the more obvious the decline of grease life. For example, when the temperature is 90 ~ 100 degrees, the service life of grease will be reduced by about half for every 19 degrees of temperature increase,while when the temperature is 10 ~ 150 degrees, the service life of Skf Bearing Operation grease will also be reduced by half for every 15 degrees of temperature increase.
which the grease is used are also important factors for its Skf Bearing Operation deterioration. For example, if the grease is mixed with wear particles such as copper, iron, lead and bronze, it will catalyze the oxidation of grease.
In short, there are many reasons for the failure of lubricating grease, sometimes caused by one reason, but it is more the result of the interaction of multiple factors, or take one reason as the breakthrough, and then other reasons work together.
In use, the lubricating grease will be subjected to mechanical shear and Skf Bearing Operation centrifugal force at the same time. Under the action of mechanical shear and centrifugal force, the lubricating grease will be thrown out of the friction interface to separate the oil,
resulting in the reduction of lubricating grease content and cone penetration and hardening. To a certain extent, the lubricating grease will be completely ineffective; Under the action of mechanical shear, the structure of lubricating grease will be damaged (such as the separation or orientation of soap fiber),
resulting in softening, decrease of Skf Bearing Operation consistency and increase of oil precipitation, which will eventually lead to failure. Under normal circumstances, if the transmission speed of lubricating grease is increased by 2000r / min,
its service life will be reduced by about half. Under high shear stress, the rotating speed is doubled and the service life is only 1 / 10 of the original life.
Free base refers to the excess base that does not interact with fatty Skf Bearing Operation acids in the manufacturing process of soap based grease;
Free organic acid refers to the fatty acid that is not saponified in the manufacturing process, or the acid contained in the alkyl fat itself (naphthenic acid), or the oxidation or saponification decomposition product of mineral oil in the fat.
Although you can install “free” all kinds of SKF Bearing seals, 36% of the early failure of bearings are still due to incorrect grease technology and improper use. Any bearing with improper lubrication will inevitably fail in normal life.
Machinery and equipment bearings are usually difficult parts of the work, and there will be a problem without fixed lubrication. In the case of manual maintenance, it is Skf Bearing Operation impossible to realize the automatic lubrication system,
which can be developed to achieve the lubrication effect. The need for grease, tools and effective lubrication technology will help to significantly reduce downtime.
