Gearbox foot mounting
NOTICE
▶
For gearboxes G50BS113 ... G50BS166, the foot is supplied loose and can be mounted to the
gearbox in three positions. Depending on the installation situation and installation space,
the foot can first be screwed to the machine housing and then to the gearbox or vice versa.
Lenze recommends using studs when mounting the gearbox with the foot mounted on the
machine housing.
▶
For gearboxes G50BS195 ... G50BS245, the foot is integrated in the housing.
