How often should shafts be turned to maintain spares?

Turning shafts periodically is essential in maintenance practices as it helps prevent issues like corrosion, deformation, or seizure due to prolonged inactivity. The choice of quarterly maintenance aligns with recognized best practices in reliability engineering. By turning the shafts every three months, you ensure that lubrication is distributed evenly and that any potential wear or material fatigue is identified early before it leads to equipment failure.

In many industries, quarterly intervals are manageable and frequent enough to mitigate risks without imposing excessive labor or downtime on operational processes. This cadence allows for regular inspection of the components and maintenance actions that might be necessary, supporting overall asset reliability.

Other intervals, such as monthly or annually, might not be as effective. Monthly might introduce unnecessary wear or be impractical for all assets, while annually could lead to unacceptably high risks of failure during longer non-operational periods. Therefore, quarterly maintenance represents a balanced approach in supporting asset reliability while being resource-efficient.
