Your benefits

Different cover sizes
enable cost-effective adaptation to the required performance data such as torque and overhung load.

The optional integrated backstop
allows a further system function to be transferred to the drive while retaining the same dimensions.

The different cover sizes ensure
optimum configuration of the bearing service life.

Covers with height-adjustable motor platforms
enable simple installation of an electric motor via belt pulleys in particularly confined spaces.

For gear units with input shaft assemblies, eight different, power-dependent cover sizes designated AD1 to AD8 are available for attachment to the gear unit. It is irrelevant whether the gear units in question are helical, parallel-shaft helical, bevel or helical-worm gear units. Up to five power-dependent cover sizes can be attached per gear unit size. This ensures ideal adaptation to the individual drive application. Each step up to the next cover size means that higher power ratings can be mounted and provides higher reliable input overhung loads.

SEW-EURODRIVE also offers the input shaft assemblies with optional motor platforms, backstops and centering shoulders.
