UCNFF-125 and UCNFF-155 are semi-standard products (delivery confirmation required).
The allowable torque has specified for a rotational speed of 1500 min⁻¹.
Transmit the maximum torque instantaneously startup and braking.
The static allowable thrust load applies. The load torque is zero.
The torsional stiffness value is only for the metal part.
The usage conditions permit greater eccentricity or angular misalignment than specified allowable values.
