Standard Shaft Hole Diameter: d

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.)
