Product Description

Features
S series have more sizes with a reduced variety of parts Increased power capacity, lower noise and higher efficiency by grinding and modifying gear The all-in-one box provides higher rigidity and higher vibration resistance. More ratios satisfy the need of accurate output speed. Reducers can be supplied for either horizontal or vertical installation in any angles.

S series is one kind of Helical worm gearbox ,designed as Modularization and high-stainless cast iron case . It is combination of helical gear and worm gear ,which with higher efficiency and strength than simple aluminum worm gearbox . Due to their outstanding efficiency, these drives can be used in every industrial sector and tailored to individual torque and speed requirements. The gear ratios afforded by the helical-worm gear stage and the low noise levels during operation make these gear motors ideal low-cost solutions for simple applications
