From a part number, Central checks DIN / ISO / EN standard, exact dimensions with tolerance class, dynamic and static load ratings, material grade, RoHS / REACH / ATEX, CAD references, and datasheet links — with sources attached.
They're built on the values engineers and procurement actually compare. Tolerance class, dynamic and static load, DIN / ISO / EN standard, material grade, cert body and number, CAD reference.
Your supplier row has the first three columns. Every other field is empty, vague, or copied from a marketing bullet.

The data engineers, procurement, marketplaces, and AI agents all rely on. Each field comes back with the source, confidence, and review state attached — no rounding, no invention.
Each job ships a verified output, not a draft. Sources attached, confidence per fact, marketing hype refused.
Stop publishing "47 mm OD". Central pins each dimension to its ISO tolerance class — bore 20 H6, OD 47 h7, width 14 — never rounded, never inferred.
"Industrial grade" isn't a field. DIN 625-1:2017 is. Central returns the full standard ID, edition year, and clause — sourced from DIN, ISO, or BSI, not a distributor.
Load ratings sourced from the manufacturer datasheet, with unit (kN) and basis (ISO 281). No rounded marketing figures, no copy-paste from a competitor row.
"Steel" isn't an answer. 100Cr6, 1.4401, A2-70, EPDM, NBR. Material grades come back to ISO/DIN designation with the source attached.
The compliance fields that decide whether a part can ship. Each one returned with the issuing body, declaration date, and document ID — never the supplier's "yes".
"Premium quality." "Industrial-grade." "Maintenance-free." Held until the record can anchor them to a verified spec, standard, or test result.
The same SKF 6204-2RS1. Sparse supplier import on the left. The Central record on the right — grouped by section, every fact cited, every hype claim held.
The same 6204-2RS1 record adapts into Google Merchant Center fields, ChatGPT Shopping JSON-LD, and a distributor-ready custom CSV — each tuned to its destination's character limits and field rules.

Central returns the full standard ID with edition year (e.g. DIN 625-1 : 2017, ISO 15 : 2017, EN 10088-3), sourced from the manufacturer datasheet or the standards body — never from a distributor row. Each is stored as a structured field with its source attached.
Yes. STEP, IGES, and 2D PDF references are captured as structured fields, with the manufacturer URL stored alongside. The same record exposes datasheet PDFs and declaration-of-conformity documents — each cited with confidence and source.
Dimensions are never returned as bare numbers. Bore, OD, width, and thread fields come back with the ISO tolerance class (H6 · h7 · k6 · M-fit), and GD&T form / position tolerances are captured where the datasheet provides them. Rounding is refused.
Each compliance field is anchored to the issuing body and a declaration document — RoHS 2011/65/EU, REACH SVHC, ATEX zone & category, UL file number. The supplier saying "yes" isn't enough; Central looks for the DoC or cert reference.
