What is a centrifugally lift off sprag?

A centrifugally lift off sprag freewheel is a precision mechanical component designed to transmit torque between a rotating shaft and a stationary part. It operates on the principle of centrifugal force, allowing the sprags — or wedging elements — to disengage from the raceway at high speeds. This unique feature ensures wear-free operation above a certain speed threshold, making it an ideal solution for applications that require high-speed rotation with minimal maintenance.

 

Why choose a centrifugally lift off sprag?

Choosing a centrifugally lift off sprag freewheel offers numerous advantages. Its wear-free characteristic above a given speed extends the component's lifespan and reduces downtime for maintenance. The design accommodates high speeds with low lubrication requirements, further simplifying system design and upkeep. Specifically tailored for gear reducers, motors, pumps, ventilators, and turbines, this type of freewheel excels in demanding environments. Additionally, it comes in various support configurations to suit different applications: non self-supported types such as RSBI, RSCI, and RSBF/CR for compact installations, and the bearing supported RIZ for scenarios requiring robust support. Opting for a centrifugally lift off sprag ensures reliability, efficiency, and adaptability in critical power transmission applications.
