Cylindrical three-stage reducers 1C3U-160 … 1C3U-250

Horizontal cylindrical three-stage reducers C3U of general machine-building application (C3U-160, C3U-200, C3U-250) is intended for changing torques and rotation frequency.

These reducers are used on various sites in connection with other equipment. It will take up very little space due to their compact dimensions. Installed on devices and various devices, it reduces the rotation frequency, but at the same time increases the torque.

Cylindrical three-stage reducersCylindrical three-stage reducers of 1C3U: conditions of use

• constant and variable, unidirectional and reversible load;
• work is long or with periodic stops;
• rotation of shafts in any direction;
• the rotation frequency of the input shaft must exceed 1500 rpm;
• atmosphere of types I and II according to GOST 15150-69 with air dust content of no more than 10 mg/m3;
• climatic versions U, T for accommodation category 1-3 and climatic versions UHL and O for accommodation category 4 according to GOST 15150-69.
