Conveyor Idler Rolls Offer Easy Upgrade Path
Bucyrus International says its Flex Pal series conveyor rolls
offer a convenient upgrade path to high-quality idlers for
underground applications. Featuring a unique retrofit design,
Flex Pal rolls are claimed to be easily integrated into existing structure and are available in CEMA C
and D ratings with 4-, 5- and 6-in.
diameters for belt widths ranging from
30–60 in. According to the company,
Flex Pal rolls can be used with carrying
assemblies for roof-hung, floor-mounted
and wire-rope structure; all three types
use Bucyrus handle and pin rail connections.
Installation is quick, with no special
tools required. Idlers comprise two
steel rolls and one center roll made from
Exalon—a proprietary high-molecularweight
polyethylene—because this roll
is subject to the greatest wear and
requires more frequent replacement.
Exalon, according to Bucyrus, not only
offers two to three times the life of a
steel roll, but is also lightweight, sound
dampening and resistant to material
buildup. All Flex Pal rolls are greased
for life with Positive Automatic
Lubrication. A spring-loaded compensator
disk allows grease to expand when
hot and compresses it as the bearing
cools. This ensures a constant pressure
on lubricant in the bearing regardless of
changes in volume. Each roll is marked
with a unique serial number to allow
tracking throughout its service life.
