Every supplier link is checked
Each candidate page is fetched and read before it is shown. A listing is only presented as verified when the part number is found on the page itself.
Engineering investigation assistant
What is this component? Identify it from a photo.
Component Detective reads markings, geometry and connectors, compares candidates and shows you the evidence — then helps you find the exact replacement. Built for engineers, technicians, maintenance and procurement teams.

- ✓Evidence & uncertainty
- ✓What to check next
Sample output
Deep groove ball bearing, double-sealed
Probable — one check outstanding
- ✓ Series digits legible on outer ring

Identify by component type
Full library →How an investigation works
Five stages, in the order an engineer actually works.
- 01
Identify
Photograph the component from several angles. Every view is analysed together, along with any manual or datasheet you attach.
- 02
Verify
See the evidence behind the identification, what is uncertain, and exactly which checks to complete before you rely on it.
- 03
Understand
Function, how it works, where it is used, specifications with their source, and the failure modes to inspect for.
- 04
Replace
The specifications a replacement must match, interfaces and ratings, equivalent types and the questions to put to a supplier.
- 05
Find
Where can I buy the exact part? Manufacturer and authorised distributor listings, each link checked, with availability, lead time and price side by side.
Identify it. Verify it. Find it.
Need to replace an unknown component?
Upload a photo or enter a part number. Component Detective helps you identify it, verify it, find the exact replacement and compare suppliers.
Stop searching supplier catalogues manually. Once a component is identified, Exact Part Sourcing looks for that exact part at the manufacturer and authorised distributors, checks each link, and tells you plainly when an exact match cannot be verified — with the closest verified alternatives instead.
Availability and lead time, honestly
Price, stock and lead time are shown only where the supplier publishes them, with the time they were last checked. Nothing is estimated.
Evidence, not a shopping result
Each result explains why we believe it is the exact part — part number, manufacturer, specification and documentation matches — and says plainly when it is not verified.
Built for field conditions
Multi-photo investigations
Up to eight photos per component. Add another angle after the first result and the whole set is re-analysed.
Document-grounded answers
Attach manuals, schedules or datasheets. Anything drawn from them is labelled as document-sourced.
Honest uncertainty
Confidence is explained, not asserted. When the evidence does not support a specification, the report says so.
Your data stays yours
Photos are stripped of location and device metadata before analysis. Reports and projects stay on your device.
Accuracy over confidence
An identification is only useful if you can trust what it does not know. Component Detective states the evidence behind every conclusion, labels each specification with where it came from, and refuses to invent part numbers, ratings or compatibility. Where the photographs cannot answer the question, it tells you which photograph would.
Reports are an engineering aid, not an authority. Always verify against the manufacturer’s documentation before ordering, installing or working on equipment.
