JF0428Z Automatic High Temperature Grease Life Tester

Product Introduction
The JF0428Z Automatic High Temperature Grease Life Tester is designed to evaluate the high-temperature life performance of lubricating grease in bearings according to SH/T 0428 and ASTM D3336.
The tester uses computer-controlled automatic operation and automatically determines the test result. After the test bearings and grease samples are installed, the instrument performs the intermittent test procedure according to the applicable standard without requiring continuous operator supervision. This reduces manual workload and improves testing efficiency.
The JF0428Z also incorporates automatic fault detection and shutdown functions. Test data can be automatically stored, queried and displayed as curves and numerical results, providing an integrated solution for high-temperature lubricating grease evaluation.

Performance Features
• Fully automatic computer control: Automatically executes the test procedure after sample installation.
• Automatic result determination: The system automatically evaluates the test results.
• High-speed DC motor: Motor speed reaches 10,000 r/min ±200 r/min.
• Digital speed display: Real-time motor speed display with adjustable speed and overload protection.
• Standard-compliant bearing fixture: Test bearing tooling is designed according to the applicable test requirements.
• High-temperature heating: Electric heating supports temperatures up to 371°C.
• Precision PID temperature control: Digital PID controller with Pt100 sensor provides ±1°C temperature control accuracy.
• Fixed loading system: Stable radial and axial loading helps reduce loading deviation.
• Automatic fault protection: The system detects faults and automatically stops operation to help protect the equipment.
• Automatic data recording: Test time, curves and results are automatically recorded and stored.
• Windows-based operation: Computer control with a Chinese-language interface.
• Easy fixture replacement: Bearing fixtures are convenient to install and remove.
• Durable heating chamber: Insulated heating chamber with a long-life dry-heating electric heater and stainless-steel housing.

Working Principle
The JF0428Z evaluates the high-temperature service life of lubricating grease by operating a specified test bearing under controlled temperature, speed and load conditions.
After the bearing is filled with the test grease and installed in the fixture, the computer-controlled system starts the test according to the programmed procedure. A high-speed DC motor drives the bearing while the electric heating system maintains the specified test temperature.
The bearing is subjected to the specified loading conditions, while the Pt100 temperature sensor and PID controller continuously monitor and regulate the temperature. The system records the test time and operating data automatically.
When a specified test condition or fault occurs, the system can automatically identify the condition and stop the equipment. Test data are stored and presented numerically and graphically for subsequent analysis.
