Bearing reliability Chesterton® Lubri-cup EM and 615 high-temperature greases


The vertical bearing of the hydra pulper often failed due to severe conditions (water and chemicals). Lack of lubrication was also a large concern due to limited space available to access the bearing nipple and the subsequent safety issue for grease application, which often led to frequent equipment failure.
