About Partmatch

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.

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:

1
Geometry — bore diameter, outer diameter, and width must be exact matches.
2
Sealing— seal type is mapped across brand naming conventions (SKF “2RS1” = NSK “DDU” = NTN “LLU”).
3
Load ratings — dynamic and static load ratings are compared against tolerance bands.
4
Speed — maximum operating speed (grease/oil) is verified for compatibility.

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.
