High performance, low weight pulley
October 1st 2011 By switching from conventional
pulleys to the new Bryant TuffCore
alternatives, conveyor manufacturers
and users alike will reap benefits,
according to UK distributor, R. A.
Rodriguez.
The pulleys are
designed to meet the speed and
performance needs of modern
handling systems. Suitable for OEM
design or for retrofitting, they are a
cost effective option to stainless steel
and are said to provide greater
design flexibility than traditional
types.Weighing up to 50% less than
their steel shell counter- parts, they
need less drive power.
The pulley comprises a TuffCore
foam roller around a steel shaft that
is lagged, as standard, with TuffCoat
Durathane. It's this combination of
material that gives the Bryant pulley
its low weight and low vibration
features.These are said to contribute
to longer bearing life and reduced
gearbox wear. There is also less
inertia to overcome so conveyors can
start, stop and reverse quickly and
index accurately; useful in tasks such
as shrink wrapping.
Improved balance and run-out are
further advantages claimed for the
Bryant TuffCore, important factors
on high speed conveyor applications.
The total indicated runout of the
Bryant product is typically 90%
better than its conventional steel
counterpart. The foam and lagging
combination eliminates the need for
balancing, again reducing cost. More articles from R A Rodriguez UK Ltd: |
