Product Manual

Reducers having hollow output shafts are usually shaft-mounted to the
driven load. If no output flange or secondary base is used, a reaction
arm prevents the reducer housing from rotating.
Do not mount reducers with the input shaft facing down. Other than
that, they may generally be mounted in any orientation. If the reducer is
vented, be sure the vent plug is moved to a location as close as possible
to the top of the unit, as shown in the examples below.
