Ducom Roll Stability Apparatus for High Temperature is used to determine the roll stability and wet shear stability of lubricating grease in accordance to ASTM D1831 and D7342.
Reliable and Robust
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.
