1,Highly Standard Modular Designed: The S series helical worm gear reducers are connected with and driven by different types of motors or other kinds of input power .The same type geared motor can be adapted to optioned powers of motors. It is therefore easy to realize different solutions for varied requirements.
2,Ratio:Featured many closely divided ratios and wide ranges of them. Very big final ratios can be obtained through combined unites to reach extremely low output speeds.
3,Mounting Arrangement: No strict limitation to the mounting arrangement.
4,High Strength,Compact Dimension: Housings are made of high strength cast iron. Gears and shaft gears are finished with a gas carburizing process and precise grounding to sequentially get a high loading capacity of per certain volume.
5,Long Service Life: Under the conditions of accurately selecting type size and the normal maintenance and use, main components(except those easily-disabled parts ) can last as long as up to more than 25,000 hours. Easily-disabled parts include lubricating oil, oil seals, and bearings.
6,Low Noise: All key components are finished by precise machining, accurate assembly, and finally tested, and therefore, fairly low noise is reached.
7,Highly Efficiency: The efficiency of the gear unit is more than 95%, The efficiency of worm gear unit can reach 89%.
8,Large Radial Loading Ability
