Tolerance Compensation
and the ability to influence the radial

for Stepless ® Ear Clamps
Always quote the 8-digit part number
when ordering (see Technical Data Sheet
or price lists of OETIKER Clamps and Rings)
Condition of the Steel Edge
The independent strip processing facilities apply stringent controls
to ensure that bandsteel edges are smooth. This greatly reduces the
potential for damage to the hose material.
Tolerance Compensation
By closing the clamp ear with a recommended, uniform force – with
force priority – component tolerances within the working range of a
Stepless® Ear Clamp can be compensated. To achieve this, the ear
gap must vary according to the actual size of the parts.
For perfect sealing, ear clamps must be closed correctly. For detailed
information, please see the Technical Data Sheet for the relevant product
group.
Dimensions, Identification and Ordering
OETIKER Clamps and Rings are manufactured to metric dimensions.
For identification purposes, the nominal diameter is stamped on
each product. For example, “145” stands for an open (nominal) clamp
diameter of 14.5 mm.
As a general rule, a nominal diameter should be chosen so that the
outside diameter of the elastic hose (when assembled onto the
connecting part e.g. hose stem) lies slightly over the middle of the
clamping range (see Technical Data Sheet or price lists of OETIKER
Clamps and Rings).
For detailed information,
please request the Technical
Data Sheet for the relevant
OETIKER product group.
OETIKER Ear Clamp with Dimple – the Original
The OETIKER System has the ear with a dimple. As the geometry of
the closed ear is kept very low, the clamping force is increased and
creates a spring effect when the hose material expands or contracts
in response to thermal or mechanical influences such as temperature,
vibration, etc.
