Gates 20-IDL-SPRK (7720-1600) Idler
Out of stock
This Gates idler sprocket is a precision drive component for maintaining correct belt tension and wrap angle in Gates belt drive systems. Using genuine Gates idler components ensures the drive geometry matches the published Gates drive design, maintaining belt life and power transmission efficiency.
Where this product is used
Gates idler sprockets guide and tension synchronous belt drives where additional belt control is required. Common applications include:
- Synchronous belt drive systems requiring an idler sprocket to maintain belt tension and wrap angle
- Gates Poly Chain and PowerGrip drive layouts where belt deflection without tooth engagement is needed
- Industrial drives subject to span flutter or layout constraints requiring additional guiding elements
Key specifications

Selecting the right option
Gates idler sprockets provide non-driven belt guiding and take-up in synchronous drive systems. Confirm the pitch and profile match the belt series — Poly Chain GT idlers are profiled differently from HTD. Not sure which idler suits your layout? Contact AIMS for assistance specifying idler components, or with full drive design.
