Selection According toTorque ® The maximum starting torque of the driver or driven machine must not exceed the maximum torque capacity of SITEX . With uniform loading and well aligned ® ® shafts, SITEX can be operated at all torques up to the maximum. In case of irregular torque, consider that the SITEX coupling can bear peak loads up to 3 times the nominal torque indicated. The values shown in the table for radial and angular misalignment, must be adjusted in cases where they are simultaneously acting on the coupling. The sum of the admissible value (A) and the respective values shown in the table must be lower or equal to 1. Mounting Instructions » Attach the hubs to the shafts, taking care to align the inner surfaces with the corresponding shaft ends. » Insert the sleeve on the two hubs adjusting the distance (dimension “b”) of the same ones trying at the same time to align the two shafts as much as possible. » Tighten into position the two elements to be coupled. » Before rotating the coupling, be sure the sleeve is free to move axially. 3 T Coupling nominal torque Nm KN T Coupling maximum torque Nm Kmax W Weight kg J Coupling moment of inertia kgm2 ΔK Maximum axial misalignment mm a ΔK Maximum radial misalignment mm r ΔK Maximum angular misalignment ° w n Maximum rpm min-1 max
