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.
Challenge
- Frequent bearing change outs
- Grease drying issue
- Frequent smearing and surface distress issue
- Premature roll surface cracks
- Increased roll grinding frequency
Expectation
- Higher relubrication interval
- Grease film should not break down which protect the bearing surface from smearing & surface distress isssue
- Grease should not get dry out
- No frequent bearing change outs & should have increased roll grinding frequency
Recommendation
MOSIL RBG 400
Application Benefits
- Customer application related challenges like frequent bearing failure, frequent roll grinding issue and premature roll surface crack issues got resolved by offering superior quality grease along with price benefit
