Description:
The roller freewheel operates on the principle of wedge or cam action. When torque is applied in the desired direction, the rollers roll along the ramps or inclined surfaces, causing them to wedge between the races and transmit rotational motion. This engagement allows torque to be transmitted from the outer race to the inner race.

Attributes:
• Designed to handle high torque loads.
• Compact and space-efficient.

Applications:
A roller freewheel, also known as a roller clutch or roller one-way bearing, is a type of one-way clutch that allows rotational motion in one direction while preventing motion in the opposite direction.
