Performance Note: The torque capacity of keylessclamped hubs is governed by many factors, includingshaft hub bore diameter, clamp size, and otherinstallation variables. Keyless coupling hubs with boresizes less than approximately one-half the maximum bore listed may not transmit the torque rating of the disc pack. Consult factory if your application is of high torque/small shaft variety.
