Important
Before installation and commission of the product begins, these installation and operating instructions
must be read carefully. Notes of caution, and hazard warnings, should be read and understood.
These installation and operating instructions apply on condition that the product meets the selection
criteria for its proper use. The selection and dimensioning of the product are not the subject of these
installation and operating instructions.
If these installation and operating instructions are not observed or are interpreted incorrectly, this shall
invalidate any product liability and warranty of RINGSPANN CORPORATION; the same also applies
in the case that our product is taken apart or changed.
These installation and operating instructions are to be kept in a safe place and must, in the event of
onward delivery of our product –be it individually or as part of a machine –be passed on along with
the product so that the user has access to them.
Safety information
•The installation and commissioning of our product may only be carried out by trained personnel.
•Repair work may only be performed by the manufacturer or by authorised RINGSPANN agencies.
•If there is a suspected malfunction, the product, or the machine into which it is built, must be taken
out of operation immediately and RINGSPANN CORPORATION or an authorised RINGSPANN
agency must be informed.
•The power supply must be turned off during work on electrical components.
•Rotating parts must be secured by the operator against unintentional contact.
•In the case of supplies made to a foreign country, the safety regulations applicable in that country
must be taken into consideration.
German original version!
If there should be any discrepancies between the German original and versions of these installa-
tion and operating instructions in other languages, the German version shall take precedence.

1. General information
1.1. Function
The main function of the torsionally stiff gear coupling consists of transferring the torque of
one shaft end onto another shaft. Additionally, the coupling is designed to compensate for
angular, radial and axial misalignments.
1.2. General safety instructions
Safety takes the highest priority during installation and operation
To ensure this, the following safety instructions must be observed:
- During installation and maintenance work, the drive motor must be secured against un-
intended start-up and the load side locked against turning.
- Accidental contact with the coupling during operation must be prevented with a suitable
cover or protective device.
- Do not reach into the working area of the coupling during operation.
1.3. Other applicable standards.
The design of the coupling is carried out with the help of operating factors that come from
experience (see RINGSPANN catalogue “shaft coupling”). If the operating conditions (e.g.
output, speed) should change, the original design of the coupling must be reviewed to de-
termine if it is still the proper selection.
2. Design and function / parts list
2.1. Labeling
Depending on the coupling size, the parts are labeled as follows:
Hubs:
- RINGSPANN logo
- Abbreviated designation

3. Intended use
The coupling may only be installed, operated and serviced if
- the operating instructions have been read and understood,
- the executing person(s) are properly trained / qualified,
- authorization has been given by the company.
The coupling type RDZ … DTO and RDZ … DFO may only be used within the operating limits
specified in section “7. Technical prerequisites for reliable operation”.
RINGSPANN shall not assume any liability for damages that result from unauthorised con-
structional changes or an unintended use.
4. Warning signs / non permissable use
Non permissible use is determined if:
- the coupling hubs have been overheated during assembly
- the fit of the parts to be connected has not been coordinated correctly
- the parameters necessary for the selection of the coupling were not considered
properly, and/or communicated to RINGSPANN
- the tightening torques of any screw connections do not match specifications
- the coupling is not properly selected for form, fit, and function
- the shaft-hub-connection (if any used) was not designed correctly
- parts from other manufacturers are used in conjunction with this coupling
- damaged coupling parts are used in conjunction with the coupling
The further operation of coupling type RDZ … DTO/… DFO is not permissible under the following
conditions:
- if the permissible limits of use (torque, speed, misalignments, …) are exceeded
- exceeding or falling below the permissible temperature limits
- if the wear limit of the parts is reached
- Changes in resonance or the occurrence of vibrations
If the unit should be operated despite the aforementioned states, it can result in damages to the
coupling and the drivetrain.
5. Condition as delivered
Couplings are generally delivered ready-for-installation in individual parts. Upon customer re-
quest, pre-bored hubs are also available. If the hub bores are manufactured by the customer, the
information in chapter 7.3 must be observed:
6. Storage
The coupling hubs can be stored in a room that has a roof and is dry. The hubs and coupling
halves, as well as all screws and nuts, are delivered in preserved condition and can be stored for
up to 6 months. In the event of a longer storage, the corrosion protection should be refreshed.
Attention! RINGSPANN shall not assume any liability for any damages that re-
sult in the event of any non permissible use.

The maximum storage duration of the O-rings is approx. 3 years under optimum storage condi-
tions. The storage, cleaning and maintenance should be carried out in accordance with the provi-
sions of ISO 2230 or DIN 7716. Storage is best carried out in sealed polyethylene bags.
Optimum service life of the coupling is given if the storage rooms:
- have a roof and are dry,
- are free of ozone-producing equipment,
- have a relative humidity of less than 65 %,
- have a storage temperature between +41 °F and +70 °F,
- are free of condensation.

Table 7.2: Maximum permissible misalignments
The maximum permissible misalignment values (table 7.2) must be adhered to and may not oc-
cur at the same time. In the event of the simultaneous occurrence of radial and angular offset,
misalignments need to be calculated percentage-wise (see figure 7.2). If not observed, damage
to the coupling may result.

The figure 7.2 shows the relationship for radial (Kr) and angular misalignments (Kw) occurring at
the same time:
Angular misalignment
