Introduction
In the steel industry, particularly in cold rolling operations, roll neck bearings operate under some of the most demanding lubrication conditions in heavy engineering. Within a Steel industry environment, the Cold Rolling Mill is a critical asset where production continuity, dimensional accuracy and surface finish quality directly impact plant profitability.
The roll neck bearing, positioned at the interface of the work roll and drive system, is subjected to:
Extremely high radial loads
Shock loading and vibration
Water ingress
From a lubrication engineering perspective, these conditions demand a grease capable of maintaining robust film thickness under boundary and mixed lubrication regimes, while simultaneously offering superior sealing capability and mechanical stability.
