Engineering qualifications
- Negative-direction axial displacement is not allowed.
- Maximum rotation speed does not account for dynamic balance.
- Stiffness values are measured at 20 deg C.
- Inertia and mass are measured at maximum bore diameter.
- Numeric bore entries are standard supported bore diameters restricted in rated transmission torque by shaft-connection holding power.
- Bores between minimum and maximum shown in the dimensions table may be compatible; unlisted bore arrangements require manufacturer consultation.
- Recommended paired-shaft tolerance is h7, with documented special tolerance for bore 35 mm where applicable.
- B = clamp type hub; R = element hardness 97 JIS A tight-fit type.
