Precision in every rotation.
The Roll Stability Tester offers reliable, repeatable, and accurate measurement of grease shear stability under controlled thermal and mechanical conditions.
With flexible configurations, microprocessor PID control, and optional high-temperature operation, it’s the preferred choice for laboratories focused on lubricant quality, consistency, and performance assurance.

• Determination of shear stability of lubricating greases

• Quality control and specification compliance testing in lubricant production

• Evaluation of grease mechanical performance under prolonged working

• R&D and formulation optimization for industrial and automotive greases

• Study of thickener stability and additive retention under mechanical stress
