Upgrade path to Bucyrus-quality idlers with Flex Pal™


August 6, 2010

Launched in mid 2009, the Bucyrus Flex Pal™ series offers customers not currently using Bucyrus roll products an easy upgrade path to Bucyrus-quality idlers for underground applications. Featuring a unique retrofit design, Flex Pal™ rolls are easily integrated into existing structure. Flex Pal™ rolls are available in CEMA C & D ratings with 4”, 5”, and 6” diameters for belt widths ranging from 30” to 60” (76.2 cm – 152.4 cm).

Flex Pal™ can be used with carrying assemblies for roof-hung, floor-mounted and wire-rope structure, all three types using Bucyrus handle & pin rail connections. Installation is quick, with no special tools required. The idlers are of unique design, each consisting of two steel rolls and one center EXALON® roll. The center roll is subject to the greatest wear and requires more frequent replacement. EXALON® – a proprietary high-molecular-weight polyethylene – not only offers two to three times the life of a steel roll, but is also light   weight, sound dampening, resistant to material buildup, reduces belt damage, and is cost-effective.

All Flex Pal™ rolls are greased for life with Idler PAL® – 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.

Like all Bucyrus rolls, Flex Pal™ rolls are triple tested – with measurement of the three most critical parameters: rotational drag, total indicated run-out and bearing end play. And, as another industry first, each roll is engraved with a unique serial number to allow tracking throughout its service life.

Bucyrus offers a standard warranty of three years to life, as opposed to the industry standard of about six months
