Reference designation of reducer by order:

Reducer ВК - 550 - 31,5 - 33 - У3, where:

ВК - type of reducer;
550 – total distance between axes, mm;
31,5 - reduction ratio;
33 - assembly configuration;
У3 - climatic version and category of placing according to GOST 15150-69.

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