1, rust-proof performance
On the bearing grease must be rust, rust can best do not dissolve in water. Grease should have good adhesive strength, and can form a thin film on the surface of steel.
2, mechanical stability
Oil change when machining soft, resulting in leaks. During normal operation, grease will be thrown to the bearing block bearing. If the mechanical stability of fat enough, work process, mechanical oil SOAP structure collapsed, causing oil to be destroyed, and thus lose lubrication.
3, oil seal
Oil seal is required for protection from external bearings and lubricant contamination barrier, bearing operation process, whether debris or moisture cannot penetrate the bearing, in case the cause for its destruction.
Proper installation and maintenance are essential elements in play the maximum bearing service life. At the same time, must pay attention to cleanliness of bearings, bearing selection accuracy and selection of appropriate tools for installation and maintenance. In addition, the bearing must be protect against pollutants and moisture contamination and ensure a correct installation and lubrication. Bearing arrangement design, seal, lubricant and lubrication cycle, and even the specialized maintenance are important and plays the same role.
4, mixed oils
Never mix incompatible greases, if two incompatible greases mixture, its consistency is usually softened in may end up bearing damage caused by the oil easy to drain. If you don't know what kind of grease bearing the original use, you must first complete removal of bearings the old grease inside and outside, to add new oil.
5, oils of classification
Based primarily on temperature and operating conditions are case sensitive: oils can be classified according to their allowed operating temperature, consistency of grease and lubricating ability is affected by temperature, operating under a temperature of bearing must be under the same temperature to select the correct consistency and good results in oil. Oil is manufactured by different operating temperature ranges, Wen Yong can be broadly divided into low temperature use, and high-temperature grease. At the same time, there is a class of fats known as resistant to squeeze or extrusion and added molybdenum disulphide, while adding additives to enhance oil film strength.
6, the important factors in selecting oils
If error select grease the bearings of all prevention measures are also futile, select an oil, base oil viscosity at the operating temperature is that it can provide adequate lubrication is very important, mainly under the influence of temperature viscosity, as temperatures rise and fall, when the temperature is increased. Therefore, you must know the base oil viscosity at the operating temperature. Machinery manufacturers usually specify the use of certain fats, however most of the scope of application of the standard grease is very broad.
Here are some important factors to select grease: mechanical type bearing type and size operating temperature; the workload situation; speed; work, such as vibration and spindle orientation is horizontal or vertical; cooling; sealing effect; the perimeter.
