1 Fixing principles for dierent types of hollow shafts
1.1 Blind hollow shaft with clamping ring and stator coupling
If space is limited radially, a good solution is to
choose an encoder with a blind hollow shaft. This
feature makes an axial output possible, which avoids
adding anything to the radius. To prevent the encoder
rotating with the shaft, it is fitted with a flexible sta-
tor coupling, which has also been designed to add as
little as possible to the radius.
• Key characteristic: Minimal radial space
• Fixing: Clamping ring
• Available in the 600 and 500 serie
1.2 Through-going hollow shaft with clamping ring
This assembly is the most space-efficient axially. The
encoder’s hollow shaft is mounted directly on to the
mating shaft, meaning there are no protruding shafts
or intermediate couplings taking up valuable space. A
clamping ring is used to fix the encoder to the mating
shaft.
• Key characteristic: Short build length
• Fixing: Clamping ring
• Available in the 800, 700, 600 and 500 series
1.3 Blind hollow shaft with axial xing screw
A common fixing solution is to secure the encoder’s
hollow shaft to the mating shaft using an axial screw.
With a prepared mating shaft, assembly can be
performed quickly and easily, during both manufac-
ture of the machine and servicing. This solution also
facilitates the process of centering the encoder to the
mating shaft.
• Key characteristic: Easily accessible assembly
• Fixing: Axial screw
• Available in the 800, 600 and 500 series

When a 26 mm mating shaft is used the recommend-
ed screw length is 20 mm. If the shaft is made shorter
the length of the screw must be prolonged accord-
ingly so that minimum 9 mm thread is in use.
