- UCNF-125T7 and UCNF-155T7 are semi-standard products (delivery time confirmed).
- The allowable torque indicates the case, 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 indicates the static allowable load, the load torque is zero.
- The torsional rigidity value is for the metal parts only.
- The moment of inertia and mass are shown for the maximum shaft hole diameter.
- The usage conditions, it possible to use with greater eccentricity or angular misalignment than the allowable values. Please contact us.
- Please insert the shaft correctly up to the J dimension line.
- The recommended shaft tolerance is h6. (A shaft diameter of 35 mm, it corresponds to a tolerance of up to +0.010 mm.)
