Sakai UCN-T7 Series Precision Compensation Coupling

Manufacturer: Sakai Manufacturing Co., Ltd.
Model: UCN-T7 Series

Feature

By using a taper clamp specification, shaft tightening can be achieved with a small tightening torque

Confirm delivery time for UCN-125T7 and UCN-155T7, which are standard products.
Indicate permissible torque at 1500 min⁻¹ rotational speed.
Transmit maximum torque momentarily startup and braking.
Represent permissible thrust load as the static permissible load with zero load torque.
Apply torsional rigidity value to the metal part only.
Represent moment of inertia and mass as maximum values at the largest outer diameter.
Insert the key securely using the recommended method.
Use recommended tolerance H6. (Accommodate h9 tolerance for a 35 mm shaft diameter.)
Use at an offset or angle greater than the permissible value if conditions allow. Contact us for more information.
