Working Principle:
The Sprag clutches get automatic released (because of change the contact point due to specially formed cam) and the unit becomes free (wheel) and when the same race is rotated in the opposite direction, These Sprag clutches, often provide the simplest and effective solutions for many applications, comparatively to clutches based on the ratchet and pawl type. Extensive range of cam, contact free – Centrifugal lift of sprag clutches have wide selection options for unidirectional drive – Sprag clutches.

In the simplest application, Sprag clutches connect and disconnect two rotating shafts (drive shafts or driven shaft).

In these devices, one shaft is typically attached with an prime mover unit and the other shaft provides output power for work.

The Sprag made of a special alloy steel and precision formed will provide high wear and fatigue life.

Sprag clutch races are precision ground, provide high concentricity and surface finish to obtain smooth Sprag rotation and manufatured from high-quality alloy steel achieving high surface hardness & core toughness.
