Spare parts & industry: two characters set two parts apart
A 6204-2RS bearing and a 6204-ZZ bearing share the same number. They are not interchangeable.
The suffix that changes the part
In technical parts, the suffix carries the essential meaning — seal type, pressure class, nominal diameter (the detail of each attribute). A text engine sees a two-character variation and treats the references as equivalent. Your buyer, meanwhile, fits the wrong part on a production machine.
Part number and technical variant
The industrie rule pack activates when you pick this industry, at indexing time. It produces these annotations, each becoming a usable filter:
| Annotation | What it isolates |
|---|---|
RLT_6204 | the bearing number, series 6000 to 6399 |
ETANCH_2RS | rubber-gasket sealing |
ETANCH_ZZ | sheet-metal shield sealing, ZZ as well as 2Z |
PN16 | the pressure class, PN6 through PN40 |
DN50 | the nominal diameter, with or without a space after DN |
On top of those: the make — SKF, FAG, NSK, NTN, Timken, INA —, the profile of a V-belt (SPA, SPB, SPC or SPZ, followed by its length) and the size of an O-ring, “40x3” as well as “o-ring 40 x 3.5”. The sealing code then reattaches to the number whatever the order in the label: “6204-2RS” and “2RS 6204” both produce RLT_6204_2RS. That is what makes a supplier nomenclature usable without rewriting it.
Three parts, taken as they are
| Indexed reference | What the engine extracts |
|---|---|
| Bearing 6204-2RS SKF | RLT_6204 · ETANCH_2RS · MARQUE_skf · FAM_ROULEMENT |
| V-belt SPA 1200 | COURROIE_spa_1200 · FAM_COURROIE |
| Brass fitting PN16 DN50 | PN16 · DN50 · FAM_RACCORD |
Four spellings, one single part
The same part is ordered under four spellings: “6204 2RS”, “6204-2RS”, “6204RS”, “6204 2 RS”. Without structure recognition, each spelling returns a different result — and your catalog looks incomplete when it isn't.
The number separated from the variant
The industry pack separates the number from the sealing variant. You find the exact reference and can knowingly suggest neighboring variants — what a generalist engine merges or misses.
A term specific to your catalog that the pack still misses (an internal supplier codification, for example)? Add your own Custom Rule from the console, simply describing what it should recognize — no regex required.
Index your technical catalog
The getting started guide covers the full setup, from sign-up to your first indexed catalog. The documentation details every endpoint.
Watch the breakdown happen. The table above is the engine's output, not hand-written. The same mechanism runs on the home page, with no signup — on a hardware or fashion catalog, not spare parts. What you see there is the annotation mechanism itself, the one the industrie pack applies to your bearing references and nominal diameters.
