- The moment of inertia and mass are calculated, the shaft hole diameter is at its maximum.
- Be sure to insert the mounting shaft up to the J dimension.
- The recommended shaft tolerance is h6. (Shaft diameter 35mm, tolerances of 0 to +0.010 are supported.)
- The allowable axial displacement represents the case the deviation angle is zero.
- The maximum rotation speed does not take dynamic balance into consideration.
- The 🟤 mark indicates a non-standard hole diameter (delivery confirmation hole diameter).
