The NIC-PMD1650R01.4610 worm is the original spare part mounted on the crankshaft of the electromechanical operators NICE TOONA at 230V.
It is a fundamental component of the motor/gearbox unit, responsible for the transmission of motion and the correct kinematics of the operator.
This wormless screw is not the one on which the nut of the arm movement screw slides, but it is the main screw integral with the electric motor, dedicated to the reduction and transmission of movement to the internal gears.
Verified spare parts compatibility for the following TOONA 220V models:
TO4006
TO4005
TO4015
TO5015
TO5016
Ideal spare part for maintenance or overhaul of the motor/gearbox unit when the following are found:
Tooth wear
abnormal play during movement
mechanical noises
failure to transmit motion
Replacing this worm screw allows you to restore the operator's efficiency while maintaining the original performance NICE.
