- UCNF-125B and UCNF-155B are standard products (delivery time confirmation required).
- The allowable torque is shown for the rotational speed is 1500 min-1.
- The maximum torque is the torque that can be transmitted instantaneously startup and braking.
- The allowable thrust load is the static allowable thrust load, the load torque is zero.
- The torsional stiffness is the value for the metal part only.
- The moment of inertia and mass are shown for the maximum shaft hole diameter.
- Depending on the usage conditions, it may be possible to use with greater eccentricity or angular misalignment than the allowable values.
- Please ensure to insert the mounting shaft correctly according to the specified method.
- The recommended shaft tolerance is h6. (A tolerance of h6~h7 can be accommodated for shaft diameters of 35mm or more.)
- For UCNF-55B, the standard shaft hole diameter of φ24 will become φ40mm.
