Indexing clutch The Hilliard Corporation

Intermittent Drive Unit (IDU)
The Hilliard Corporation’s IDUs are packaged mechanical assemblies that produce precise intermittent motion – on demand – from a constantly rotating input.

IDUs feature a self-contained lubrication system, making them ideal for dusty, dirty, steamed or washed-down applications. The heart of these units is a Hilliard single revolution clutch. They are designed to provide up to 40 million cycles, with no accumulation of error in the stopping position.

When combined with an acceleration-deceleration unit (ADU), our IDUs provide smooth acceleration and deceleration through 360º - on demand.



Intermittent Drive Assembly (IDA)
Hilliard’s new IDA provides automatic control of intermittent motion from a constantly rotating power source.

This easy-to-install, self-contained package includes a solenoid-operated, single revolution clutch with anti-rollback and anti-overrun features. The rugged and proven, round-roller/cam-flat, single revolution clutch provides positive engagement at any point of revolution of the driving sleeve without slip, lag, or cumulative error.

Designed to replace and to provide greater life than wrap-spring assemblies, the Hilliard IDA is built to last through millions of cycles.
