Component Sets : RV-E Series

The Standard in-line RV-E reducer provides high-end performance in a very compact and highly rigid component type configuration. The unit incorporates rolling contact elements to provide high efficiency and long life, integrated angular bearings to support external loads and a 2-stage reduction design to reduce vibration and inertia while increasing ratio capabilities.

The Nabtesco Precision Reducer consists of a patented two-stage cycloidal design that provides large torque, high-ratio and significant shock-load capabilities with extreme precision and excellent quality. The RV utilises rolling contact elements to reduce wear, extend life and lower backlash with the unique pin and gear structure of the cycloidal design providing higher shock resistance than traditional reducers and further reducing backlash. The reducer also incorporates a set of large, internal angular support bearings that provide large moment capacities and negate the need for external support devices.

The virtually symmetrical gear design and the support of all shafts by roller bearings guarantee a constant performance during the lifetime and allow short time peak loads of up to 5 times the given rated torque (i.e. for emergency stops).
