R57 helical gearbox
Description
R57 SERIES horizontal shaft gearbox CHARACTERISTICS:
1、R series horizontal shaft gearbox are designed based on modulization system. They can easily fit with many types of motors or connect with other power input. The same type of reducers can fit motors with different power. It is possible to combine or connect different types of machines.
2、Structure compacted, save mounting space, long life time.
3、High transmission efficiency. A single model reducer can reach a transmission efficiency up to 96%.
4、Precise division of transmission ratio with a wide range. The combination model can form large ratio and result a low output rotation speed.
5、Various ways of installation: horizontal installation at any position or flanged installation.
Our In-line helical gear drive are available in many sizes and gear ratios. They can be supplied in optional versions such as stainless steel or explosion-proof models, and combined flexibly according to our modular concept. In combination with our inverter technology, these products offer you a perfect drive solution made tailored to your individual applications and requirements.
