[Specifications]
*Check the Max. Torque for the Shaft Diameter list as there may be limitations on the standard and maximum torque caused by the holding power of the coupling shaft section.
*The max. rotation speed values do not take into account dynamic balance.
*The static torsional stiff ness values are analysis values for the element taken at a temperature of 20°C at maximum bore diameter.
*The moment of inertia and mass are measured for the maximum bore diameter.
[Dimensions]
*The nominal diameter for the clamp bolt M is equal to the quantity - the nominal diameter of the screw, where the quantity is for a hub on one side.
*The values in ( ) of the STF-019, d1 or d2 is the value in the case of ø8mm.
*The escape in the internal diameter of the element is equal to dimension d2 (large diameter) plus ø0.9 mm.
* The rated dimension tolerance for countershafts is h7 class.
[Standard bore diameter]
*The bore diameters in the boxes marked by [●] are used as standard bore diameters.
*Check the table for information on max. torque for the shaft diameter as there may be limitations on the standard and maximum torque determined by the holding power of the coupling shaft section depending on the bore diameter used.
[Max. torque for the shaft diameter]
*Check the this list as there may be limitations on the standard and maximum torque caused by the holding power of the coupling shaft section.
*The Max. limit-received torque is a torque value of the small diameter side (d1). However, only in the case that STF-019SA1's d1 or d2 is φ8mm does the clamp bolt size down, so the limiting value is 0.8N・m. Please keep this in mind.
