The maximum size with disc spring couplings for high-output applications is an outer flange diameter of 262 mm and rated torque of 8000 N・m. Single-element types with high torsional stiffness and flexible double-element floating-shaft types that connect double elements with an intermediate floating shaft are available. The floating shaft is particularly able to handle the setting of lengths according to customer requirements.

Choose your own mounting system
Pilot-bore products are a standard part of the line-up, so they can handle shaft coupling by means of a key, shaft coupling by shrink-fitting, and more. SFH S/G-K-K types that use frictional coupling are also available, giving you freedom in choosing your mounting method.
Can be assembled from part components
Since we deliver products as components, you can safely use them even in designs that cannot be mounted once assembled.

*If you require a product with an LS dimension other than that above, contact Miki Pulley with your required dimension [mm]. Please contact Miki Pulley for assistance if LS ≧ 1000.
*The nominal diameters of each bolt and tap are equal to the quantity minus the nominal diameter of the screw threads times the nominal length. The quantities for the pressure bolt M1 and detachment screw hole M2 are quantities for the hub on one side.

*The bore diameters marked with ● or numbers are supported as standard bore diameter.
*Bore diameters whose fields contain numbers are restricted in their rated torque by the holding power of the shaft connection component because the bore diameter is small. The numbers indicate the rated torque value [N·m].

* Positions of set screws and keyways are not on the same plane.
* Set screws are included with the product.
* Positioning precision for keyway milling is determined by sight.
* Contact Miki Pulley when the keyway requires a positioning precision for a particular flange hub.
* Consult the technical documentation at the end of this volume for standard dimensions for bore drilling other than those given here.
