A comprehensive engineers' reference source for radial ball bearings and thrust ball bearing




An analysis of continuous rotating torque over 360 or more can be a powerful tool in determining a variety of application-related bearing problems. MicroTorqueTM testers manufactured by Measurement Research, Inc. have torque resolution to 10 mg-mm (0.000014 oz-in) and can show raceway damage, contamination, misalignment and lubricant issues in small bearing assemblies.
