The decision this case can inform
Use this record when building a predictive-maintenance operating system that includes people, data review, bearing stores, work execution, and production accountability.
SKF supplier case spanning several years and multiple simultaneous changes. The availability trend is reported, but no controlled attribution isolates one intervention.
What the public record actually establishes
- F1
Before 2005, the plant reportedly lacked an effective predictive-maintenance system and held inconsistent or damaged bearing stock.
- F2
Plant staff collected vibration data for specialist analysis in South Africa, supported by machinery mapping and annual training.
- F3
The program also rationalized bearings and introduced an air-conditioned, controlled bearing store.
- F4
SKF reports rotary-kiln availability above 96% in 2010 versus below 83% in 2004; 2010 output was just under 900,000 tonnes.
Facts and reported results are kept separate from the lesson a plant may choose to test.
Operating context
Plant reportedly lacked an effective predictive-maintenance system and had breakdowns, low availability, high cost, and inconsistent bearing stores.
Intervention or finding
Vibration monitoring, specialist analysis, staff training, bearing rationalization, and improved storage were implemented.
Documented result
Supplier reports rotary-kiln availability rose from below 83% in 2004 to above 96% in 2010.
Plant interpretation
Build predictive maintenance as a capability and work-management system, not a sensor purchase.
Transfer boundary
Multiple changes occurred over six years; contribution of any one intervention is not isolated.
Questions to verify at your plant
These are decision checks, not operating instructions. Resolve them through local risk assessment, technical review, and authorization.
- 01
Is there a governed route from condition observation to diagnosis, planned job, post-repair verification, and learning?
- 02
Are collection quality and analysis competence controlled, including for low-speed and variable-load assets?
- 03
Do storage, handling, interchangeability, and contamination controls protect the spare before installation?
- 04
Can availability change be separated from production demand, outages, rebuilds, and other concurrent improvements?
