Bi-directional clutch The Hilliard Corporation

Hilliard Bi-Directional overrunning clutches replace expensive shifting and drive train assemblies. These clutches provide positive engagement automatically in either direction.

Manufactured exclusively by The Hilliard Corporation, these unique clutches feature rugged, field-proven components and are easy to service in the field. Because they can overrun in either direction, Hilliard Bi-Directional overrunning clutches are ideal for such functions as bi-directional and dual-source drives.

A specially designed unit was recently used by Polaris Industries to produce the first 4-wheel drive, all-terrain vehicle capable of providing automatic front-wheel drive engagement in both forward or reverse models.
