Generation X.e industrial gear units

Generation X.e industrial gear units

For operators or original equipment manufacturers of machines and plants, it is crucial that the drives used there are robust, reliable and easy to maintain. The industrial gear units of the X..e series efficiently meet these requirements.

The intelligent, universal gear unit concept impresses with its fine size graduation, high installation variability and the large number of additional modular features and options such as motor adapters, backstop, various sealing and shaft systems, and many more. The wide ratio range of 6.3 - 450 and the robust design make the All-Rounder the right choice in many industries and applications. Whether crane, conveyor belt or mixer - with the X..e series and the industry know-how of SEW-EURODRIVE, you are opting for maximum availability and a reliable partner. And if our modular system does not have the right solution for you, we will customize our gear units for you.
