Helical Speed Reducer Cast Iron Housing R Series Flange Mounted AC Motor Foot Mounted High Overload Capacity
Product Introduction
This series supports flexible installation methods: providing two options: foot installation and flange installation. Foot installation is widely used in standard production lines, while flange installation is suitable for space limited installations. Its compact structure saves valuable workshop space and has strong transmission efficiency: the two-stage model can reach up to 96%, the three-stage model can reach up to 94%, and the R/R combination model can reach up to 85%, effectively reducing energy consumption during daily operation.
The R series is widely used in various industries and is an ideal choice to meet various industrial needs. It is suitable for the light industry, food and beverage (beer, dairy products), and chemical industries, where stable, low maintenance transmission is crucial. In addition, it is also suitable for scenarios such as escalators, automated warehousing systems, building materials machinery, steel metallurgy, as well as environmental protection, power plants, mining, papermaking, port/airport logistics, etc. Whether it is small-scale production or heavy-duty operation processes, it can meet the general transmission needs of most industrial fields.
