ROLL STABILITY APPARATUS

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.
