Key Features
Measures Both Static and Dynamic COF
The system automatically determines:
- Static Coefficient of Friction (COF)
- Dynamic Coefficient of Friction (COF)
allowing users to evaluate material slip characteristics throughout the entire movement process.
High-Precision Force Measurement
Equipped with a high-resolution force sensing system, the tester delivers reliable friction measurements with a resolution of up to 1/500,000 and force accuracy of ±0.5%.
This ensures consistent and repeatable results for research, quality control, and production verification.
Wide Speed Adjustment Range
The testing speed can be freely adjusted from 0.01 to 1000 mm/min, making it suitable for different material specifications and testing standards.
Users can simulate actual material movement conditions encountered during packaging and manufacturing operations.
AC Servo Motor Drive System
A precision AC servo motor provides smooth motion control, stable speed performance, and excellent repeatability throughout the testing cycle.
Compared with conventional drive systems, servo control minimizes speed fluctuations and improves measurement consistency.
High-Resolution Displacement Control
The displacement system provides a resolution of 0.001 mm with ±0.5% accuracy, ensuring precise travel control during every test.
Flexible Sled Weight Configuration
The tester supports multiple sled weights to accommodate different material types and testing requirements.
Standard weight options include:
- 5 g
- 10 g
- 20 g
- 200 g
- 500 g
Additional custom weights can be supplied upon request.

What Does a COF Test Measure?
A coefficient of friction test evaluates the resistance encountered when one surface moves against another.
The RS-8030G measures:
- Static Coefficient of Friction (μs): the force required to initiate movement.
- Dynamic Coefficient of Friction (μk): the force required to maintain movement.
These values help manufacturers predict material behavior during production, packaging, storage, transportation, and end-use applications.
Reliable friction data can reduce production issues such as feeding errors, sticking, slipping, unstable stacking, and packaging line downtime.
