ISO 606 Short-pitch roller chains, A and B series

Is ISO 606 still current?

Yes, but a revision is coming. It is still in use, but a revision is in progress. The current reference is ISO 606:2015 (MechAtlas review: 23 October 2026). Check the publisher before you specify it.

What it covers

Short-pitch roller chains, A and B series

Equivalent and related standards

“Similar” never means interchangeable without an engineering check.

Parts that use ISO 606

• Roller chain (ISO / EN, main)
  Short-pitch steel chain of pins, bushes and rollers that drives sprockets; used on conveyors, feeders and drives.
  Grades: A series (from ANSI) and B series (European)
  Includes chains, attachments and sprockets; revision in progress.
• Chain sprocket (ISO / EN, main)
  Toothed wheel that engages a roller chain to transmit power; used on chain drives and conveyors.
  Sprocket tooth form is part of the chain standard.
