Helical-bevel gear units from SEW-EURODRIVE provide a high degree of efficiency of over 95% in both torque directions and at all input speeds – performance designed to last. High-endurance gearing enables high-torque, wear-free operation long into the future. The remarkably high efficiency of our helical-bevel gearmotors makes them energy-savers. As they also have a long maintenance-free service life, they can be used in every application with AC asynchronous motors and synchronous servomotors.

Installation of angular gear units is particularly space-saving. The attenuation characteristics are a further bonus resulting from the simplicity of the mechanical design. As a result of longitudinal application of the force on the input shaft, the torque impulses are dampened. The noise level for this device is very low, even when a large amount of force is applied. This means that our helical-worm gearmotors can be used even for stage elevators.

The variety of sizes allows almost all requirements to be met. For high output speeds, the RX57 to RX107 series of single-stage gear units offers compact, space-saving solutions. And applications where weight is an issue will benefit from our multi-stage gear units: Thanks to their die-cast aluminum design, the models R07, R17 and R27 are three particularly efficient lightweights – ideal as satellite drives and for use in light machine constructions.
