Hollow shaft cover
Sealing cap
The bore of the hollow shaft is sealed using a plastic sealing cap.
Gearboxes in size 39 and larger with hollow shaft and shrink disk
have a rotating protective cap.
The dimensions of the rotating protection cover can be seen in
the dimensional drawings provided in the gearbox chapters.
For safety reasons, stationary protection covers may be
required.
Protection cover
For sizes 39 to 189, a stationary protection cover for the hollow
shaft and hollow shaft with shrink disk can be selected.
Sizes 19 and 29 have, as standard, a stationary protection cover
for the design with shrink disk. For the design with hollow shaft,
for sizes 19 and 29, a protection cover can also be selected.
The dimensions of the protection cover can be seen in the sep-
arate dimensional drawing provided in the gearbox chapters.
■
Radially reinforced output shaft bearings
The gearboxes can be supplied with the standard design or with
a reinforced output shaft bearing design. The reinforced bear-
ings allow higher radial and combined forces (radial and axial)
to be absorbed.
