Bearing friction torque is an important factor affecting bearing noise, vibration, and lifespan, and is a key indicator for measuring the dynamic performance of bearings.
Application
The bearing friction torque tester is a precision instrument specifically designed for measuring the friction torque of bearings. Its main purposes include, but are not limited to, the following aspects:
Bearing Quality Assessment
By measuring the friction torque of bearings, the quality level of bearings can be evaluated, including their manufacturing precision, material properties, and lubrication effects, etc.
Bearing Optimization Design
Friction torque data is an important basis for bearing optimization design. By testing the friction torque of bearings with different design schemes, their performance can be compared, and thus the best design scheme can be selected.
Standards
GB/T 32562-2016:Rolling bearings - Measuring methods for friction torque
JJF1137-2024:Calibration Specification for Bearing Friction Torque Measuring Instruments
Feature
High-Precision Testing: Utilizes electromagnetic analytical balance technology to achieve high-precision measurement of miniature bearing friction torque.
Multiple Measurement Modes: Supports various measurement modes including real-time, peak, first peak, and average.
Intelligent Monitoring: Features intelligent quality monitoring and rapid calibration functions, allowing for measurement results to be processed on a PC without disassembling the sensor.
Data Storage and Reporting: Automatically stores test data and generates test reports, facilitating user analysis and record-keeping.

Drive mechanism, etc.
Test Procedures
Bearing Installation: Install the bearing to be tested on the test equipment, ensuring that the installation is secure and the concentricity error does not exceed ±0.05 mm.
Preloading: Apply the specified axial and radial preload according to the type of bearing and its application.
Starting the Bearing: Start the bearing at the specified speed. After the rotational speed stabilizes (generally no less than 5 minutes), begin the measurement.
Recording Friction Torque Values: During the measurement process, record the friction torque value every 1 minute for 10 consecutive times, and take the average value as the measured friction torque value under this operating condition.
