DGBB Intake Fields

Launch Paths

Input path	Minimum fields	Meaning
Exact part number	identity.selected_part_number	Best path when the bearing designation is known.
Dimensions + manufacturer	dimensions.d, dimensions.D, dimensions.B, identity.manufacturer	Manufacturer-backed search from core geometry.
Dimensions + bore type	dimensions.d, dimensions.D, dimensions.B, bore.bore_type	Geometry-backed search when brand is unknown.

Core Parameters And Symbols

Field key	Label	Meaning	Example
identity.selected_part_number	Part Number	Exact bearing part number/designation.	6205-2RS1/C3
identity.manufacturer	Manufacturer	Bearing brand or manufacturer.	SKF, NSK
dimensions.d	Bore d (mm)	Inside diameter of the bearing bore.	25
dimensions.D	Outside Diameter D (mm)	Outside diameter of the bearing.	52
dimensions.B	Width B (mm)	Bearing width.	15
bore.bore_type	Bore Type	Bore geometry such as cylindrical or tapered.	CYLINDRICAL
series.series_code	Series Code	Bearing series code shown in the designation.	62, 63
closure.closure_category	Closure Category	Shield/seal style or protection family.	2RS, ZZ
clearance.clearance_code	Clearance Code	Internal clearance class.	C3
precision.precision_value	Precision Class	Precision class if known.	P6

Requirement Parameters

Field key	Meaning
requirements.operating_speed_rpm	Operating speed the replacement must support.
requirements.lubrication_mode	Lubrication context, for example grease.
requirements.clearance_required	Required internal clearance if application-specific.

Input Notes

• d, D, and B are the core bearing geometry symbols.
• A part number can encode suffixes for closure, clearance, and precision; still expose those fields when known.
• Dimensions alone are a partial anchor. Manufacturer or bore type makes the launch path strong enough.
• Closure, clearance, speed, precision, and snap-ring details often decide whether a row becomes DROP_IN, CONDITIONAL, or REJECT.
