Description
TSUBAKI RS120-2B1 — Sprocket RS120-2B, genuine TSUBAKI product.
Overview
The TSUBAKI RS120-2B sprocket is a double-strand sprocket with a hub on one side, built for RS120 duplex roller chain. Two rows of teeth share the load, so the drive can carry roughly double the power of a single strand at the same pitch. It is used in heavy-duty conveyors, mixers, crushers and industrial drive trains.
Key Features
- Double-strand tooth rows for duplex chain
- Single-side hub for keyway and set screws
- Hardened teeth on many tooth counts
