20% reduction in grease consumption and reduction of roll failure frequency through an increase in relubrication interval
Castrol's expert team faced multiple challenges in run-out roll bearings due to adverse weather conditions. To overcome the issue Castrol suggests 860/220-2 molub alloy.
Mollub Alloy | 860/220-2 Heavy Duty Grease |
The challenge:
A renowned manufacturer faced multiple challenges in run-out roll bearings due to adverse weather conditions, constant uptime, and heavy load. This resulted in 6 roll failures every 14 days, increasing operational costs by $3900 due to frequent replacements. Regular inspections displayed that previously used grease was unsuitable for adverse climatic conditions and had softened and run off from the bearing cavity. The water-cooled bearings also required daily lubrication to function.
The solution:
We recommended Castrol’s Molub-Alloy 860/220-2 ES Heavy Duty Performance Grease with the following criteria
- Decrease roll failures to 3 every 14 days
- Adequate lubrication for the bearing cavity
- Increase relubrication interval for water-cooled bearings
- Reduce lubrication usage
The business benefit:
- Annual roll replacement savings of 78 units = $50, 700
- Decreasing lubricant costs by 20%
- Reduction in roll replacement labour by 20%
