.:: HOW TO READ DIAGRAMS ::.  
 

The joint capacity to transmit a regular torque at a constant load with no shocks, for a more or less long period, mainly depends on the number of revolutions per minute and the inclination angle ° of the two axes. The diagrams of this section have been conceived on the base of this criterium.

Each curve corresponds to the joint size (outside diameter "D") and represents the torque that the joint can transmit depending on speed and working angle °.

The diagrams can be directly read if angle ( °) is 10°. For wider angles, torques are reduced, therefore the values are to be corrected using the correction factors (F) relating to the angle shown in the table.

  

   
  IMPORTANT:
Diagrams' values are merely indicative and are referred to the single joints only.

When chosing a double joint, you have to consider that this one can transmit a torque about 10% lower than the same sized single joints.

Each application has its own particular motion characteristics, such as:shock loads, motion reversals, connected masses, kind of starting, presence of elastic joints, stops and starts, etc.,that have to be considered by the user when chosing the joint.
