Safety and Guideline Signs
DANGER
Immediate and impending danger, which can
lead to severe physical injuries or to death.
CAUTION
Danger of injury to personnel and damage to
machines.
Please Observe!
Guidelines on important points.
Guidelines on explosion protection
Safety Regulations
These Installation and Operational Instructions (I + O) are part of the coupling delivery.
Please keep them handy and near to the coupling at all times.
It is forbidden to start initial operation of the product until you have ensured that all applicable EU directives and directives
for the machine or system, into which the product has been installed, have been fulfilled.
At the time these Installation and Operational Instructions go to print, the ROBA®-ES couplings accord with the known
technical specifications and are operationally safe at the time of delivery.
DANGER
If the ROBA®-ES couplings are modified.
the relevant standards for safety and / or installation conditions are ignored.
Some ROBA®-ES coupling series Types are permitted for use in areas where there is a danger of explosion
(see page 22).
For application in Ex-areas, please observe the special safety-related guidelines and directives. The product
must be especially marked for this area.
The product will only be marked if it is ordered especially for an Ex-area.
User-implemented Protective Measures
Cover all moving parts to protect against seizure, dust impacts or foreign body impact.
To prevent injury or damage, only specialist personnel are allowed to work on the components. They must be
familiar with the dimensioning, transport, installation, initial operation, maintenance and disposal according to
the relevant standards and regulations.
Please read the Installation and Operational Instructions carefully prior to installation and initial operation of the
device.
These Safety Regulations are user hints only and may not be complete!

Function - Application
ROBA®-ES stands for:
flexible (E), backlash-free (S) shaft coupling.
The coupling consists of (see Fig. 1)
two coupling hubs and an elastomeric element (flexible, star-
shaped intermediate ring) as a single-jointed coupling
(Type 940._ _ _._)
two coupling hubs, two elastomeric elements and a
connection piece as a double-jointed coupling short
(Type 942._ _ _._)
two coupling hubs, two elastomeric elements and a sleeve
with variable length as a double-jointed coupling
(Type 943._ _ _._)
ROBA®-ES couplings are conceived specially for backlash-free
operation at comparatively high speeds.
ROBA®-ES couplings are mainly used in measurement and
regulatory technology as well as in control and procedure
technology.
ROBA®-ES couplings are shaft-shaft connections for flexible,
backlash-free torque transmission in highly dynamic servo
drives.
State of Delivery
ROBA®-ES couplings are delivered manufacturer-assembled
ready for installation (Please check state of delivery).
Depending on size or Type, ROBA®-ES coupling hubs are made
of aluminum or steel.
ROBA®-ES couplings with steel hubs and steel shrink disks have
been zinc phosphated manufacturer-side to form a basic
corrosion protection. All other components are untreated.
The hubs acc. DIN 69002 are blank and oiled.
The flexible, star-shaped intermediate ring (elastomeric element)
is pressed into specially designed claws (Fig. 3) under light pre-
tension.
Fig. 2
Fig. 3
Storage
The coupling hubs are delivered preserved and can be stored in
dry rooms protected from the weather for 6 to 9 months .
If stored under the conditions described below, the maximum
usability of the elastomeric elements is 5 years.
Damp storage rooms are not suitable.
In order to exclude condensation, the relative
air humidity should ideally total maximum 65 %.
There must be no ozone-generating
equipment, for example fluorescent light
sources, mercury vapor lamps or electrical high
voltage devices in the storage rooms.
