Free Industrial Parts Tools
Free, no-signup tools for identifying and cross-referencing industrial parts — no fabricated data. Some are instant, standards-based lookups; obsolete-part cross-referencing is researched by our order desk since there's no reliable way to automate it honestly.
Bearing Interchange Lookup
Type in a deep-groove ball bearing designation from SKF, FAG, NSK, NTN, or Koyo (60xx, 62xx, or 63xx series) and get the equivalent part number from every other brand instantly. Covers open, sealed (-2RS), and shielded (-ZZ) variants — the cases where the equivalence is a published, mechanical fact, not a guess.
Bearing Life Calculator
Enter the basic dynamic load rating C from the bearing's datasheet, the equivalent dynamic load P on it, and the shaft speed — this returns the ISO 281 basic rating life in million revolutions, operating hours and years, using the correct life exponent for ball or roller bearings and the published a1 factor for reliabilities above 90%. Everything here is the standard formula; nothing is looked up from a table of our own.
Sensor Finder
Pick a sensor type and housing size (M8/M12/M18/M30 — a real ISO thread standard shared by every brand) to see matching real, currently-published sensors across our catalog. This tool filters live products by their own published specs — it never claims one brand's part number "equals" another's.
Obsolete Part Lookup
Manufacturers replace part numbers constantly — a superseding model, a form-fit-function equivalent, or a straight discontinuation with no direct replacement. Checking a part's lifecycle status tells you whether it is still made; it does not tell you where to get one. Send us the part number and any details you have (nameplate photo, the equipment it's in, when it was purchased) and our order desk researches the real cross-reference before quoting, rather than guessing.
