Steel Cover
Type SDE for Dry Application
SDE/SME steel roll for dry and wet application with
fixed or adjustable bow:
Surface characteristics
- Ground for sensitive web material.
- Sandblasted to increase roll surface coefficient of friction.
- Grooved to prevent sheet floating at high web speeds.
- Hard chrome-plated when
the surroundings are humid
and the web material is
particularly abrasive.
- Chrome-PTFE-coated,
WoCa-PTFE-coated or well
polished with highly
adhesive media.
- Tungsten-carbide coated
to increase the surface
coefficient of friction.
Design characteristics
- Proprietary precision
ball bearings with
lubrication for life.
- Stable, dynamically
balanced support
in tubes.
- Double supported
spool segments.
- Precise, steady running
of supporting tubes.
- Flexible coupling
elements with ideal
damping constant,
soft starting and
vibration reduction
during operation.
- Low starting momentum
and low power requirement
as a result of optimum
number of ball bearings.
