Mounting and wear control is possible.This is a premounted unit of shaft and roller bearing. There are versionswith different dimensioning dependent upon the gear unit size and thepower to be transferred. A variant of the free drive shaft exists in additionto the coupling versions. Sufficiently large dimensioned tapered-rollerbearings allow for high external loads. In addition, a backstop can beintegrated in all versions.A variety of motor adapters is available dependent upon the motor size to bemounted. Gear units with free drive shaft are closed by a cover at this point.They are used for mounting the motor.Different seal options are possible dependent upon the application conditions.The elastic element provides a form fitted connection of the two coupling halves.Dependent upon the size, it can be mounted directly on the motor shaft.T39
