## About the Roll Stability Tester

Ducom Roll Stability Tester is used to simulate the changes in consistency of lubricating grease between rollers and outer race of a bearing. 

The test cylinders are loaded with grease uniformly on the inside wall and a weighted roller is placed inside the cylinder. The test cylinders mounted horizontally upon a set of driving and guide wheels which rotate the cylinder at the set rpm. The temperature in the test area is controlled precisely  using a closed loop temperature controller.

## Technical Specifications

- **Rotational speed:** up to 300 rpm
- **Temperature range:** up to 200°C
- **Preset timer:** 1 minutes to 100 hours
- **Temperature control accuracy:** ±1°C

## Features

- Designed for long duration test at high temperature
- Uniform heating arrangement with good thermal insulator chamber
- Bench top model integrated with electronic controller
- Automated cut-off when upper chamber hood is removed

## Test Standards

- **ASTM D1831:** Standard Test Method for Roll Stability of Lubricating Grease
- **ASTM D 7342:** Standard Test Method for Prolonged Worked Stability of Lubricating Grease in Presence of Water (Water Stability Test)
