Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
SupportFunction ⊑ DesignedFunction
Realized in
SupportingProcess ⊑ PlannedProcess
The identity-giving function is to support and locate mechanical elements, which is a specific type of mechanical support that enables relative motion while maintaining positional control and reducing friction
2 Genus DeterminationDeterminação do Gênero
MaterialArtifactbfo:Object (BFO_0000030)
While ISO 15926 suggests SUPPORT as a parent, this is not available in our enriched classes. CFIHOS places it under 'other mechanical equipment' which is too vague. Bearings are typically monolithic or simple assemblies that function as single causally unified artifacts designed for support, fitting MaterialArtifact. They lack the complex assembly structure that would require Assembly classification.
3 Differentia SpecificaDiferença Específica
∃bearerOf.SupportFunction ⊓ ∃participatesIn.FrictionReductionProcess

A bearing is distinguished by its designed function to support mechanical elements while reducing friction in the connection.

The SupportFunction is the core identity-giving function inherited from the genus level. The participation in friction reduction processes is what distinguishes bearings from other support components like brackets or foundations.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

The supporting surface is the minimal essential part common to all bearing types. Specific subtypes will have additional parts (balls, rollers, races, bushings, magnetic elements) but the supporting interface is universal.

TransformationTransformação
mechanical load transfer with friction reduction and motion constraint
Bearings receive mechanical loads and transform them into controlled, low-friction support that enables or constrains relative motion between mechanical elements
Disjoint WithDisjunto com
Valve Pump HeatExchanger Compressor
C4: Valve, Pump, HeatExchanger, Compressor. Bearings have incompatible process signatures with fluid handling equipment - they handle mechanical loads rather than fluid streams
