Bearing in running a little negative clearance maximum bearing life. But actually to maintain the bearing this best state is very difficult to change once certain conditions of use, the negative clearance is increased, thereby incurring a significantly reduced bearing life or fever. Usually select the initial clearance, the running clearance is taken to be only slightly greater than zero.
Bearing operation if used improperly, it will produce a series of problems, so we should pay attention to these issues, in order to detect the problem and solve the problem in order to guarantee the normal use of the bearing. General bearing in operation, pay attention to the following three matters.
First, check the status of the running machine monitoring, in order to avoid equipment downtime.
Second, if the bearing lubrication is insufficient or excessive lubrication, a lubricant containing a magazine, an excessive load, bearing damage, lack of space, and the Seal, the heat generated by friction, etc..
The high temperature repeatedly said in an abnormal situation. Bearing high temperature is also harmful to the lubricant in the bearing. Sometimes bearing overheating can be attributed to the bearing lubricant if bearing long-term operation at temperatures over 125 degrees Celsius, will reduce bearing life.
Third, it is best to open the bearing box, check the bearings and periodically check the oil seal. Check the situation near the bearing at the oil seal, to ensure that they are adequate to prevent hot liquid or corrosive liquids or gases infiltration along the axis of the bearing, bearings good lubrication, and correct the barrier debris and moisture, oil seal should not wear. oil seal If you wear should be replaced as soon as possible.
Oxidation Stability refers to the use of the grease in the long-term storage or long-term high temperature resistance to the role of the heat and oxygen, and the ability to maintain its nature does not occur permanent change. Reduce free alkali content or free organic acid content increases, the dropping point decline, appearance become darker in color, a different smell, consistency, strength limit, similar to the viscosity decreases, generate corrosive product and destruction grease structure, often occur because the oxidation substances, soap oil separation. Therefore, in the the grease long-term storage, it should be stored in dry and ventilated environment, prevent sun exposure, and should regularly check the free base or free organic acids, corrosive and other changes to ensure its quality and performance.
