- Highly Standard Modular Designed: The products are easily connected with and driven by different types of motors or other kinds of input power. The same type of geared motor can be adapted to the optioned powers of motors.It is therefore easy to realize different solutions for varied requirements.
- Ratio: Featured many closely divided ratios and a wide range of them. Very big final ratios can be obtained through combined units to reach extremely low output speeds.
- Mounting Arrangement: No strict limitation to the mounting arrangement.
- 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 high loading capacity of per certain volume.
- Long Service Life: Under the condition 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. Easi-ly-disabled parts include lubricating oil, oil seals, and bearings.
- Low Noise: All key components are finished by precise machining, accurate assembly, and finally tested, and therefore, fairly low noise is reached.
- High Efficiency: The efficiency of the gear unit can reach 95%, and The efficiency of the worm gear unit can reach 89%.
- Large radial loading ability.
- Axial load ability of up to 5% of radial load.
