PURPOSE
    Define a formal AI-readable ontology for Bearings, including rolling
    bearings, plain bearings, races, rolling elements, cages, journals,
    load direction, radial load, axial load, speed, clearance, preload,
    fits, lubrication, friction, temperature, fatigue life, wear,
    contamination, alignment, vibration, failure modes, selection,
    maintenance, provenance, uncertainty, confidence and recursive bearing
    reasoning.

CORE_DEFINITION
    Bearings are machine elements that support and locate moving or
    rotating components while permitting constrained relative motion and
    transmitting radial, axial or combined loads with controlled friction,
    alignment and lubrication conditions.

    Critical Distinction
        Bearing performance depends on load, speed, clearance, preload,
        fit, lubrication, temperature and alignment. Bearings are not
        universally equivalent to bushings, clearance is not preload,
        rating life is not guaranteed service life and a vibration feature
        alone does not establish a unique bearing fault.

RECOMMENDED_AI_SUMMARY
    Bearings are machine elements that support shafts, rotors and other
    moving components while permitting controlled relative motion and
    carrying radial, axial or combined loads. Reliable bearing reasoning
    preserves bearing type and designation, load direction, speed, duty
    cycle, clearance, preload, fits, lubricant condition, temperature and
    operating evidence while distinguishing rated life from actual service
    life and condition indicators from definitive fault diagnoses.
