In general, deep groove ball bearing brand are factory has its own specialized design personnel external packaging design, and arrange for clearance of the plant production conditions of production, so the packaging from the line to the blocks of color are very clear, unambiguous, and package part of brand and specifically with the unique design in order to protect their intellectual property.
To be printed on the brand ", label in SKF bearing body. Font is very small, but it is mostly used plants Chupin stamping technology, but without the heat-treatment is carried out before the embossing, so the font is small, but the concave too deep, very clear. The font counterfeit products not only fuzzy, due to the printing technology of rough, fonts, floating on the surface, some even can be easily wiped off by hand.
The left hand holds the bearing SKF bearing inner sleeve, the right hand toggle coat make its rotation, listen to whether there are miscellaneous ring. As most of the backward condition of counterfeit products, completely hand-workshop-type operations, in the production process will inevitably be an impurity in the sand type, hidden in the deep groove ball bearing the body, so the rotation will be issued when the noise. This is the biggest and strict implementation of production standards, and used the machine operation is plant of different brands.
This should pay particular attention to the purchase of SKF bearings. Because of the current anti-rust technology is not the special home, very easy to leave a thick layer of oil, so the bearing body for rust prevention processing, get in the hands of sticky stiff, and bearing the original abroad almost can not see the traces of rust preventive oil, pour is particularly careful experts said bearing smells a taste, certainly the anti-rust oil, just impossible to see.
The so-called deep groove ball bearing chamfer, also is the horizontal and the vertical surface junction, counterfeit bearings due to restrictions on production technology, processing satisfactorily in these corners.
Vibration damage to the SKF bearings can be said to be quite sensitive, spalling, indentation, rust, crack, wear will be reflected in the measurement of bearing vibration. So, through the use of special bearing vibration measuring device ( frequency analyzer etc) can measure the size of the vibration, through frequency cannot be inferred from abnormal situation. The measured values, and different bearing conditions of use or sensor installation location, therefore require prior to each machine measurement comparison criteria.
High temperature often SKF bearings in an abnormal situation. High temperatures may also be harmful to the bearing lubricant. Sometimes overheated bearings can be attributed to the bearing lubricant. If the bearings at the temperature higher than 125 DEG C long-term even would reduce bearing life. Cause of high temperature bearings causes include: insufficient or excessive lubrication lubrication, lubricant. Contains impurities, heavy load, bearing damage, lack of space, and oil have high friction and so on.
Therefore continuity SKF bearing temperature monitoring is necessary, whether measured or other important parts of the bearing itself. If it is in operation under the same conditions, any temperature changes may have trouble.
Regular SKF bearing temperature can be measured with the help of the thermometer digital thermometer, for example, can be accurately measured bearing temperature according to C or Fahrenheit temperature display unit. The importance of the bearing, means when it is damaged, will cause the equipment downtime, so this type of deep groove ball bearings preferably should be equipped with a temperature detector.
