Reference designation of reducer by order:

Reducer ЦДН - 630 - 50 - 12 - У3, where:

ЦДН - type of reducer;
630 - distance between axes of low-speed stage, mm;
50 - reduction ratio;
12 - assembly configuration;
У3 - climatic version and category of placing according to GOST 15150-69;

Note
Version of low-speed shaft end is cylindrical - Ц.
Version of low-speed shaft as a part of toothed coupling is produced according to assembly configurations 11, 12, 21, 22, 31, 32.
It is possible the production of this type of reducers with reduction ratio 9, 11.2, 14, 18, 22.4, 28, 35.5, 45.
