INA one-way bearing using noise impact on the running - bearing grease
INA bearing running clearance in slightly negative, the biggest one-way bearing life.
But actually should keep bearing the best condition is very difficult, once some using conditions change, then the negative clearance, to incur a significant reduction in the bearing life or fever.
Therefore, often requires choosing initial clearance, running clearance off for only a slightly greater than zero.
INA bearings in operation if use undeserved, can produce a series of problems, so we should pay attention to these problems, in order to find problems and solve problems in time, to ensure the normal use of the one-way bearing.
Usually outside the spherical bearing in the operation should pay attention to the following three items.
First, check the status of the operation of the machine, monitoring, lest cause the equipment downtime.
Second, if the bearing lubrication is insufficient or excessive lubrication, lubricants containing magazine, heavy load, outside the spherical bearing damage, clearance, and the oil seal of high temperature and friction and so on.
High temperature often said bearing is in abnormal situation.
High temperature also harmful to within the bearing lubricant.
Sometimes bearing overheating can be attributed to the INA bearing lubricant.
If a one-way bearing in more than 125 degrees Celsius temperature operation for a long time, will reduce the bearing life.
Third, the best when open the bearing box, check the bearing and periodically check the oil seal.
Check of the condition of the near the bearing oil seal, in order to ensure that they are enough to prevent hot corrosion along the axis of the liquid or gas into liquid or outside the spherical bearing, bearing if get good lubrication, and cut off the right moisture and debris, said oil seal should not wear.
, if oil seal was worn, it should be replaced as soon as possible.
Oxidation stability is refers to the grease when used in long-term storage or long-term high temperature resistance to heat and oxygen, permanent changes in their ability to maintain its nature will not occur.
Due to oxidation, are often free alkali content reduced or free organic acid content increases, drop point drop, dark appearance, appear different smell, consistency, ultimate strength, similar viscosity decreased, generated corrosive product and destroy the material of grease, soap oil separation.
In long-term storage of grease, therefore, should be stored in dry and ventilated environment, prevent sun, and shall regularly check free base or free change of the project such as organic acid, corrosion resistance, to ensure its quality and performance.
