Abstract: A locking nut for installation on a cylinder, including a nut body defining a nut engagement surface and a directional coupling mechanism associated with the nut body, for locking the nut body with the cylinder in response to relative rotation between the nut body and the cylinder in a locking direction. The directional coupling mechanism may include a plurality of recesses, a plurality of rolling members contained within the recesses, and a retaining device for retaining the rolling members in the recesses. A method of installing the locking nut on the cylinder, including engaging the nut engagement surface with a cylinder engagement surface, inserting the rolling members in the recesses, threadably connecting the nut body with the cylinder in order to install the locking nut on the cylinder, and connecting the retaining device with the nut body in order to retain the rolling members within the recesses.
