Industrial parts data for your systems
Integrate verified cross-reference data into your ERP, CMMS, or procurement platform. Bearings, V-belts, sheaves, and roller chain. One API call returns verified equivalents across all major brands.

Quick start
curl -H "X-API-Key: pm_live_your_key_here" \ "https://api.partmatch.io/api/v1/public/bearings/search?q=6205-2RS"
Same pattern for every category — see Endpoints below.
Response format
Responses come in two shapes depending on the category.
Flat — bearings & V-belts
One row per (part × brand). Each result is a self-contained equivalent with full specs; search returns up to 20, the detail endpoint returns the single best match.

}Nested — sheaves & chain
A canonical base (geometry/dimensions) plus a brand_skus[] array of equivalents across brands. The detail endpoint returns one base object; search wraps a list of them under results.

}The equivalence_state trust signal
Every equivalent carries an equivalence_state so you can gate substitutions by confidence:
verified_equivalent— confirmed interchangeable against a manufacturer-published cross-reference.cross_reference— listed as a cross-reference; verify fitment before substituting.geometry_match— dimensional match only (bearings); no published interchange.
It's present on bearings, sheaves, and chain. V-belts don't carry it — when a belt query resolves through the Continental cross-reference table, the provenance is returned in a top-level alias_match block instead.

Use cases
CMMS Integration
Auto-suggest replacement parts when a work order is created. Verify equivalents before procurement approves a substitution.
E-Commerce Enrichment
Add cross-reference data to product pages. Show customers which parts from other brands fit their application — across bearings, V-belts, sheaves, and chain.
Catalog Normalization
Map your existing inventory to a canonical part database. Identify duplicates across brands. Clean up your parts catalog.
