From a safety perspective, the various designs of one-way bearings are often used in many situations. In order to ensure that one-way bearings can also operate in a safe and stable state, some aspects must be considered, such as their load, conversion accuracy, friction torque, and bearing seat design.

In order to prevent overload of the one-way needle roller clutch bearings, the inertia of the entire system must be considered, and the accuracy of the conversion depends on the vertical spring load borne by each needle roller to ensure continuous contact between the shaft, needle roller, and slope locking surface.

For one-way bearings, their conversion accuracy depends on factors such as conversion frequency, lubrication, fit tolerance, surrounding structure, elastic deformation of adjacent components, and driving mode. Therefore, ideal accuracy can be achieved through shaft driving.

Transmitting torque requires a rigid bearing seat. Therefore, the transmitted torque is related to the materials of the shaft and bearing seat, the hardness of the shaft, the wall thickness of the bearing seat, and the tolerances of the shaft and bearing seat. It is important to consider the driving torque and the mass inertia moment during acceleration when calculating the torque.

When a one-way bearing is idling, its frictional energy consumption depends on whether the shaft is rotating or the outer ring is rotating. If the outer ring is rotating, the frictional energy consumption will first increase with the speed, but it will gradually decrease due to the centrifugal force of the needle rollers. At this speed, there is no longer frictional contact between the needle roller and the shaft, and with the increase of centrifugal force, the needle roller separates from the shaft.

Due to the fact that the accuracy of the one-way bearing positioning hole fundamentally determines the geometric accuracy of the stamped outer ring and the function of the clutch, it is necessary to chamfer the bearing seat hole to 15 ° in order to meet the requirements.
