| Abstract: | A complex lithium based bearing grease used in motors of electric locomotives wasdeveloped by a new technology called Tribasic Acid One-stage Process- The results from the performancetest and road test indicated that the grease has high drop point and high anti-oxidation properties with longservice life. It can be used to replace imported motor greases, such as Aeroshell grease No. 7, with a ser-vice period of two years. The quality specifications of the bearing grease reach the world level of the samekind. The product has passed appraisal by the Ministry of Railways. |
