* Type A/B/C is automatically assigned by Miki Pulley according to the bore diameter combination you select and cannot be specified by the customer.

* Check the list of standard bore diameters as the rated torque may be limited by the holding capacity of the shaft connection.

* Max. Rotation speed does not take into account dynamic balance. * The torsional stiffness value is the analytical value of the element taken at a temperature of 20oC.

* Moment of inertia and mass are measured for the largest bore diameter.

* Types A/B/C are automatically specified by Miki Pulley according to the bore diameter combination you select and cannot be specified by the customer.

* Dimension d3 is the inner diameter of the element. For dimensions d2 exceeding this value, the shaft can only be fitted up to size LF to the side hub d2.

* The nominal diameter of the clamping bolt M is equal to the quantity minus the nominal diameter of the screw thread, where the quantity is for the hub on one side.

* Shaft tolerance for standard bore diameter is h7 (h6 or g6): symbol B.

* Shaft tolerance j6/k6: designation J/K is optional and is only supported for bore diameters marked with ○ .

* Hole diameters marked with ● or numbers are supported as standard hole diameters. Refer to Miki Pulleys for special arrangements applicable to other bore diameters.

* The bore diameter field containing the numbers is limited in the nominal torque by the holding capacity of the shaft connection because of the small bore diameter. The numbers indicate the rated torque [N?m].
