Component Asset
A component asset is a maintainable item recorded separately beneath a parent asset because it requires its own history, work, cost, or risk control.
What this term means in maintenance
A component asset is a maintainable item recorded separately beneath a parent asset because it requires its own history, work, cost, or risk control.
Examples of component assets
Examples include:
- Motor
- Gearbox
- Pump
- Control panel
- Instrument
- Drive
- Safety device
- Bearing housing
Practical example
A motor is stored as a child component of a conveyor so its failures, repairs, parts, and costs remain traceable.
When to create a component
Create a separate asset when the item needs independent maintenance history, PM, meter, cost, criticality, or replacement tracking.
Component versus spare part
A component asset is installed and maintained.
A spare part is inventory until issued or installed.
Common mistake
Creating every nut and bolt as a component makes the asset hierarchy difficult to use.
How this term differs
Component Asset is a separately maintained child item with its own history or control. It is related to Parent Asset, Asset Hierarchy, and Asset Register, but these terms describe different records, measures, roles, strategies, or decisions and should not be used interchangeably.
