Features
-
Economy
We have adapted general-purpose gearheads for servo applications, allowing us to deliver products economically and with Quick delivery.
-
-High efficiency
Highly efficient helical gears are used, making the most of the servo motor's capabilities.
-
・Low noise and long life
The reducer unit provides low-noise operation and long service life that were achieved through our years of experience manufacturing gear motors.
-
・Installation direction is free
There are no restrictions on installation angle, such as horizontal, vertical, or tilt.
-
・Output shaft backlash (approximate value)
Unit: minutes Reduction ratio 5~10 15~100 120~200 angle 70 40 30 *This is not a guaranteed value.

Type Name
HMTK: Right-angle shafttype using hypoid gears.
GMTK: A parallel shaft type that uses helical gears.
size
Indicates the rated input capacity.
Frame No.
This indicates the size of the reducer. For most models, this is the same value as the output shaft diameter.
It is automatically determined from the motor capacity and reduction ratio.
Mounting Type
L: Foot mount mounted type.
U: Face-mounted type.
F: Flange mounting type.
Face mount or flange mount?
It is automatically determined by the frame number.
Reduction ratio
Indicates the reduction ratio.
The range division corresponds to the frame number.
Shaft arrangement
For HMTK type
No symbol: If the mounting format is a hollow shaft type (H), the shaft arrangement symbol is not required.
S: When the mounting format is face mount (U), the solid output shaft protrudes toward the mounting surface.
T: A type with a solid output shaft on both sides.
For GMTK type
No symbol: No shaft arrangement symbol is required.
Mount Code
Specify the mount code that matches the motor you are installing.
