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

(1)GB/T 32562-2016:Rolling bearings - Measuring methods for friction torque

(2)JJF1137-2024:Calibration Specification for Bearing Friction Torque Measuring Instruments

Feature

(1)High-Precision Testing: Utilizes electromagnetic analytical balance technology to achieve high-precision measurement of miniature bearing friction torque.

(2)Multiple Measurement Modes: Supports various measurement modes including real-time, peak, first peak, and average.

(3)Intelligent Monitoring: Features intelligent quality monitoring and rapid calibration functions, allowing for measurement results to be processed on a PC without disassembling the sensor.

(4)Data Storage and Reporting: Automatically stores test data and generates test reports, facilitating user analysis and record-keeping.
