Bearing friction torque measuring instrument
►Product description of Bearing friction torque measuring instrument:
The friction torque is an important factor affecting the noise, vibration and life of the bearing and also a main index to measure the dynamic performance of the bearing.
We developed series of bearing friction torque measuring instruments according to relevant standards and user requirements.
The bearing friction torque measuring instruments are suitable for measuring dynamic friction torque (maximum friction torque, average friction torque and torque fluctuation) of various bearings, such as deep groove ball bearings, angular contact bearings, single row tapered roller bearings, etc.
►Application of Bearing friction torque measuring instrument:
It is suitable for testing the precision bearing rotation flexibility in the measuring room of bearing manufacturing workshop and quality identification of the bearing submitted for inspection by the testing institution.
►Features of Bearing friction torque measuring instrument:
Axial loading, synchronous drive, reduce of basic friction torque with air bearing, and dynamic measurement of bearing friction torque variation with integral torque sensor.
The measured curve of friction torque can provide reliable basis for users to analyze the bearing quality and further complete the optimization design of bearing and improve the processing technology. The bearing friction torque measuring instrument has obtained national patents and won the third prize for Mechanical industry science and technology progress award.
