SF series is one type of S series helical-worm gear unit with flange mounted. S series helical-worm gear unit is a reducer that is driven by a combination of helical gears and worm gears. This series of reducers we manufactured have complete specifications, wide speed range, good versatility, adaptable to various installation methods, safe and reliable performance and long service life, as well as implements the requirements of international standards.
The uneven surface of the housing has features of good heat dissipation, strong vibration absorption, to make the reducer low temperature rise and low noise. It also has good sealing performance and strong adaptability to the working environment. S series helical-worm gear unit has high transmission accuracy and is especially suitable for working in occasions with frequent starting. It can be connected to various reducers and equipped with various types of motor drives, and can be installed in a 90-degree transmission operating position. Its key components are made of high wear-resistant materials and undergo special heat treatment, which has the characteristics of high accuracy, stable transmission, small size, large load capacity, and long service life.
