The difference between the four series of reducers


The main differences between the four series of reducers (R, F, K, S) lie in their internal transmission structure, the direction of the output shaft, and whether they have self-locking function

Their common characteristics include:

Modular design: supports flexible combination, power coverage of 0.12-200kW, and expands speed ratio range;

High performance: using hard tooth surface alloy steel gears (tooth surface hardness ≥ 60HRC), grinding accuracy of 5-6 levels, and transmission efficiency generally reaching 94% -96%;
