KRL Tapered Roller Bearing Shear Tester


KRL Tapered Roller Bearing Shear Tester


● Using a tapered roller bearing test machine, under the test conditions similar to the gearbox, the lubricating oil is subjected to mechanical shear stress, resulting in permanent viscosity loss, and according to the rate of decline of kinematic viscosity before and after the test lubricant test. Indicates the viscosity shear stability of the lubricating oil.
