Bearing selection of lubricant

Bearing selection of lubricant in the bearing, the choice of lubricant is a very important factor. For uniformity, friction torque, select service life, noise, dust, heat, cooling and rust, etc. , the performance of the ball bearing has a significant impact. Ball bearing lubrication is generally adopt sealed, so few for replacement of lubricant. Lubricant used oil or grease injection mode, generally longer than oil lubrication grease life, so the sealed ball bearing lubrication grease way as the standard form. Grease lubrication life longer than oil is the combination of the thickener fibers or interweave, can keep oil ( The base oil) And the release of oil, so which has the function of maintain lubrication performance. In addition, the torque is small or not allowed to have the purpose of the friction torque fluctuation, lubricant used oil as appropriate. Lubricant, when using the oil to the service life of the point of view, sometimes with the user's specifications. Also contains prevent grease base oil oxidation of antioxidant, improve critical lubricity oily agent, to prevent the high temperature erosion of high pressure additives and rust inhibitors and other additives, these additives added makes all kinds of grease has different features. Therefore, even in a range of grease, because the manufacturer is different, the performance will be completely different. Because of the reason of the above characteristics of grease, sealed ball bearing grease life calculation, related factors of complex crisscross, so now the comparison has no practical significance. And in recent years, the proportion of the bearing assembly part use the plastic material, and grease chemical change is increasing. When choosing grease is very necessary to carefully considering the conditions of use, the use of environment.
