A complete series
covering a 100W to 55kW range
To meet requirements of customers in every field of application, we
have completed a series of products to cover a 100W to 55kW range.
Our standardized reducers cover an output torque range from 0.6kgf
. m for small capacity machines to 6,200kgf .
m for large machines.
ratios ranging from 1/6 to 1/658503
In our standardized series, the single reduction type provides
standard reduction ratios from 1/6 to 1/87 and the double reduction
type standard reduction ratios from 1/121 to 1/7569. We can meet the
requirement for a higher reduction ratio by offering a three-stage
type capable of realizing an ultrahigh reduction ratio of 1/658503.
High reduction ratios
and compact size
The inner planetary gear mechanism enables a reduction ratio of
as high as 1/87 to be realized by the single reduction with a
compact size, multi-stage reduction types such as the double and
triple reduction types are standardized.
Ultra long life realized
by the tooth form of our own creative invention
For our reducers, a unique tooth form inner planetary gear mechanism
is adopted. A long life tooth form that is free from tooth breakage
and suffers only slight wear makes the reducer extremely reliable.
In addition, it is excellent in all aspects of power, life,
efficiency, vibration, and quietness.
Tooth form precision
at the world's top level
Indexing machining of gears and carrier pin holes that are most
important in a precision gear mechanism is carried out with ultra
precision, and gears arefinished with a tooth form pitch error of
only a few micron, amazing precision. This results in ideal engaged
motion and hence very small noise, vibration, and heating.
High efficiency of
The single reduction type exhibits high efficiency of over 90% in
average because power loss is thoroughly reduced by high tooth form
efficiency, reduced slip resistance of the transmission gear due to
precision machining and introduction of new technology, and enhanced
lubrication. As the reduction ratio becomes higher with an
increasing number of stages, the difference in efficiency becomes
more remarkable in comparison with reducers of other systems.
The robust and long life design has realized maintenance-free
products in the small size lineup. A very low parts count makes
Our domestic service networks, overseas offices and factories,
including major distributors in various countries, serve our
customers both in sales and services. We have developed reliable
service networks everywhere.
