 FEATURES of Matex PLANETARY GEAR • High Torque・High Efficiency・Low Noise High Torque, High Efficiency, and Low Noise are realized thanks to our unique structure. Wide Variety of Standard Products・Speed Ratio Wide variety of size( Outer Diameterφ26mm〜φ200mm) and speed ratio(3-7) are provided. Furthermore, a higher speed ratio can be realized by stacking multiple planetary gear units. Flexible to Your Design due to its Minimal Unit Structure Minimal planetary gear unit structure and coaxial setting of input and output enable your product design compact and flexible.  LGU (UNIT TYPE)...

 MULTIPLE STAGE By stacking the planetary gear units, wider range of speed ratio is available. You can choose the right gears from the standard combination table.(See P25〜P29) Actual Speed Ratio： 4.8×4 = 19.2 ※The above drawing just illustrates one example of the LGU75 series. Please refer to each product page for other series. UNIT TYPE LGU series is Matex’s mainstream product which is unitized important parts of planetary gear. Wide varieties of gear are available. GEARHEAD TYPE LGH series is a product that is unitized planetary gear unit, shaft, and case. It's connectable to the...
