When in use requires a fairly cautious attitude, that is, change is the use of INA bearings with high performance, if used improperly, can achieve the expected performance results, and it is easy to make the INA bearing damage.
INA bearing most of the smoking bad for many reasons -- beyond the original estimate of the load, the non effective sealing, tight fit as a result of too small INA bearing clearance. Any of these factors has its special type of damage and will leave the special signs of damage.
Therefore, to examine the damage to the shaft bearing, in most cases it may cause can be found, generally speaking, there are 1/3 INA bearing damage due to fatigue damage, the other 1/3 is due to poor lubrication, the other 1/3 pollutants into the INA bearing caused by improper handling or installation.
So, we talk about how to protect it, prolong its service life, who is not willing to let INA bearing wear, durability. The use of INA bearings should pay attention to the following matters:
First, to maintain the INA bearing and its surrounding environment clean, even invisible dust into the INA bearings, also can make the INA bearing wear.
Second, use the installation carefully and accurately installed
The most important is not to allow powerful punch, does not allow direct percussion INA bearing with a hammer, and is not allowed to pass through the rolling pressure.
Third, the use of appropriate, accurate installation tool
As far as possible the use of special tools, the use of fabric and fiber or something to avoid.
Fourth, to prevent the INA bearing corrosion, do not use bubble
INA bearings are precision made of steel, but also afraid of the water, hands to take the INA bearings, to fully wash hands sweat, and coated with high quality mineral oil before operation, during the rainy season and summer with particular attention to anti rust.
INA bearing life are a certain number of years, if we make good use of the normal, attention to the above 4 points when using, INA bearings will play its role fully!
