Precise and flexible, directly from the modular system
The precision gearboxes of the RD-E series are more compact and versatile than ever before. Three variants enable numerous application options, e.g. when selecting the servomotor. Inside is a gearbox of the latest generation - highly precise, extremely resilient and particularly durable.
Coupling and flange included
The RDR-E version is designed for right-angled mounting, while the RDS-E version is designed for direct mounting. The RDP-E series, on the other hand, is designed for a belt drive. This wide range of variants allows quick and cost-effective installation in a wide variety of applications. The precision gearboxes in these series are used in machine tools, but also for positioning, palletizing and in solar technology. The precision gearboxes are supplied fully enclosed and pre-filled with lubricant. Motor coupling and motor flange for common servo motors are also included in the scope of delivery.
An alternative to the RD-E series with hollow shaft for feeding through data cables and supply lines is the RD-C series.
