Reference designation of reducer by order:

Reducer ЦТНД - 500 - 100 - 22 - У3, where:

ЦТНД - type of reducer;
500 – total distance between axes, mm;
100 - reduction ratio;
22 - assembly configuration;
У3 - climatic version and category of placing according to GOST 15150-69.

Note
Version of low-speed shaft end is cylindrical - Ц.
