The intelligence layer for industrial replacement parts
When a part fails on a production line, someone needs to find the right replacement — fast. The problem is that every manufacturer uses different part numbers for the same physical part. Partmatch solves this by verifying equivalents against manufacturer specifications, not guesswork.
Why Partmatch exists
I started Partmatch after running into the same problem too many times — trying to find an equivalent industrial part and getting either no answer or one that didn't match. The data was scattered across manufacturer catalogs, distributor PDFs, and forum threads, none of which agreed with each other. Partmatch is the tool I wanted: one place where part numbers cross-reference reliably, with sources visible.

What we do
Partmatch is a cross-reference verification tool. You enter a bearing part number — from any major manufacturer — and we tell you which bearings from other brands are verified equivalents.
Unlike standard cross-reference charts that match by series number alone, Partmatch checks four dimensions before confirming a match:
If any dimension doesn't match, we don't return a result. The “no verified equivalent” answer is the most important feature — it means we won't guess when we're not certain.
Where our data comes from
Every equivalence in our database is sourced from manufacturer specification data — not from user submissions, not from AI, and not from unverified third-party databases.
What we cover today
We started with deep groove ball bearings — the most commonly replaced bearing type in the world. Our database currently covers:
- 39 base bearings (6000, 6200, 6300 series, sizes 00–12)
- 926 base V-belts (Classical A/B/C, Narrow 3V/5V)
- 5,800+ brand SKUs across 10 manufacturers
- 830+ product pages with full specs
- 147 brand comparison pages
Where we're going
Bearings and V-belts are live today. The cross-reference problem exists across all industrial replacement parts — seals, filters, chains, and more. Each category gets its own database, normalizer, and matching engine.
Our goal: become the canonical source of truth for “what replaces what” across all industrial replacement parts.
