FASTEX IC210 Clamping element 3904de
Compact assembly and operating instructions 05/2022
Explanation regarding Machinery Directive 2006/42/EG
The clamping elements described here are components in accordance with the Machinery
Directive and do not require a declaration of incorporation.
Work on the clamping element
Only carry out work on the clamping element when it is not in operation and is not under
load. Secure the drive unit against being switched on accidentally. Attach a notice to the
switch stating clearly that work is being carried out on the clamping element. Ensure that the
entire unit is not under load..
1.3 Intended use
Only use the clamping element according to the conditions specified in the service and
delivery contract and the technical data in the annex. Deviating operating conditions are
considered improper use. The user or owner of the machine or plant is solely liable for any
resulting damage.
When using the clamping element please specifically observe the following:
•Do not make any modifications to the clamping element that go beyond the permissible
machining described in these instructions. This also applies to touch protection facilities.
•Do not use the clamping element as a torque-limiting safety element.
If you have any queries, please contact our customer service (see Service and support
(Page 12)).
1.4 Safety instructions for a clamping element for use in
potentially explosive atmospheres
The assembly supplier is responsible for the guideline-compliant design of the system
clamping element with all associated components. In potentially explosive areas, it must be
ensured that the design torque TCl according to Table 7-1 is not exceeded at any operating
point. The identification and information on the conditions of use can be found in the main
operating instructions of the assembly supplier.

The clamping elements described here are universally applicable, self-centering clamping
elements whose function is the tensionally locked transmission of torque between shaft and
hub.
The installation and operation of the specified clamping elements in combination with
cylindrically bored hubs is described in these instructions.

3 Application planning
Check the delivery for damage and for completeness. Report any damage and/or missing
parts to Flender immediately.
The coupling is delivered in preassembled groups. These may be dismantled.
3.1 Transport of the clamping element
WARNING
Severe personal injury due to improper transport
Severe personal injury due to falling components or due to crushing. Damage to clamping
element parts possible due to use of unsuitable transport means.
•Only use lifting gear and load suspension devices with sufficient load bearing capacity
for transport.
•Please observe the symbols applied on the packaging.
3.1 Storage of the clamping element
The clamping element, unless not specifically ordered otherwise, is supplied with
preservation and can be stored for up to 12 months in a dry and dust-free storage room.

4 Assembly
DANGER
Danger due to bursting of the assembly group
If not used as intended, the assembly can burst. There is a risk of fatal injury from flying
fragments. Bursting of the assembly can lead to an explosion in potentially explosive
atmospheres.
•Use the clamping element as intended
Note
Information about the assembly of the clamping element
•Only use undamaged components for the assembly of the clamping element.
•Follow the assembly sequence.
•Please ensure that there is sufficient space at the assembly location and that the
location is tidy and clean in order to be able to assemble and maintain the clamping
element without any risk.
•If a dimension drawing has been created for the clamping element, please observe the
information it contains as a matter of priority

4.1 Assembling the clamping element
WARNING
The design torque TC l must not be exceeded at any operating point. It must be
ensured that the cylinder head bolts are tightened with the tightening torques
according to Table 7-1
Preparatory work
1. Make sure the surfaces to be joined are in perfect condition.
2. Clean the contact surfaces as well as the shaft and hub.
3. Slightly oil the contact surfaces. Do not use any grease or oil that contains molybdenum
disulfide or other additives that significantly reduce the coefficient of friction.
4. Push the axial ring (2) onto the clamping hub (1).
5. Place the clamping bush (3) on the clamping hub (1). Position the clamping bush (3) so
that the release threads are offset to the slot in the clamping hub (1).
6. Screw the clamping hub (1) to the clamping bush (2) without tightening the cylinder-head
screws (4).
Assemble
1. Position the pre-assembled clamping element in the hub bore and then place both parts
on the shaft.
2. Slightly tighten the cylinder-head screws (4) so that the clamping element can still be
moved.
3. Align the Clamping element on the shaft.
4. The shaft must fill the entire length of the clamping hub (1).
5. Tighten the cylinder-head screws (4) crosswise in several turns. The specified tightening
torque can be found in the Tightening torques and widths A/F section.

5 Disassembly
Procedure
1. Loosen and remove all cylinder-head screws (4) one after the other.
2. Screw the cylinder-head screws (4) into the existing release threads of the
clamping hub (1).
3. Remove the clamping element. Use suitable lifting gear when doing this.
4. Check the hub bore and the shaft for damage and protect them against corrosion.
When reinstalling the clamping element please observe the information in the chapter
Assembly (Page 10).
