Reference designation of reducer by order:

Reducer 1Ц3У - 200 - 160 - 12 - К - У3, where:

1Ц3У - type of reducer;
200 - distance between axes of low-speed stage, mm;
160 - reduction ratio;
12 - assembly configuration;
К - version of low-speed shaft end;
У3 - climatic version and category of placing according to GOST 15150-69.

Note
Version of reducer, type ЦЗУ is similarly to type 1ЦЗУ.
Version of low-speed shaft end can be tapered - К (standard execution), cylindrical - Ц (coordinated additionally by order), as a part of toothed coupling - М (except 1ЦЗУ-160), hollow splined - П (except 1ЦЗУ-160).
Dimensions of low-speed shaft as a part of toothed coupling of reducer 1ЦЗУ are similarly to reducer type 1Ц2У.
Version of low-speed shaft as a part of toothed coupling is produced according to assembly configurations -11, 12, 21, 22, 31, 32.
