The Lubricating Grease Roller Stability Tester is designed to evaluate the mechanical stability of lubricating greases under rolling shear conditions. It complies with the Chinese petrochemical standard SH/T0122 "Grease Roller Stability Determination Method". This instrument is essential for predicting how a grease will perform in bearings and other rolling-element applications.
| DFYF-314A | Roller Stability Tester – basic configuration for standard testing |
| DFYF-314B | Grease Stability Tester – enhanced version with additional features |
Direct drive speed control – A speed-regulating motor directly rotates the roller, ensuring a stable speed of 165 ± 15 r/min without belt slippage.
Integrated air bath – Raises the ambient temperature around the roller (from room temperature up to 80°C), allowing tests under realistic thermal conditions.
Compact and attractive design – Small footprint, stainless steel construction, and a clear front cover for easy observation.
