Reference designation of reducer by order:

Reducer Ц3У - 400 - 160 - 13 - Ц - У3, where:

Ц3У - type of reducer;
400 - distance between axes of low-speed stage, mm;
160 - reduction ratio;
13 - assembly configuration;
Ц - version of low-speed shaft end;
У3 - climatic version and category of placing according to GOST 15150-69.

Note
Version of low-speed shaft end can be cylindrical - Ц, as a part of toothed coupling - М, for the connection of controller - КА.
Version of low-speed shaft as a part of toothed coupling is produced according to assembly configurations -11, 12, 21, 22, 31, 32.
