  New Cooper Bearings Raise the Bar for Capacity, Long Life

Business Wire

NORFOLK, Va. -- January 23, 2013

Cooper Roller Bearings has increased the load capacities of many of its
industry-leading split roller bearings to levels higher than any split roller
bearings of similar size, with L[10] life that is 23% to 135% longer
(depending on size). The new 01E and 02E bearings are fully interchangeable
with the popular Cooper 01 and 02 Series bearings, yet provide up to 29% more
radial capacity and 16% to 90% more axial load capacity.

Like all Cooper split roller bearings, the 01E and 02E Series are completely
split to the shaft, which eliminates the need to disassemble all components on
a shaft for service or replacement and significantly reduces downtime. The
longer L[10] life extends uptime even further, with longer intervals between

The increased life and capacities of the 01E (medium-duty) and 02E
(heavy-duty) bearings are due primarily to changes in internal geometry. The
new bearings feature the same superior sealing and energy-efficiency as their
counterparts in the 01 and 02 Series. They also share the same exterior
dimensions, giving users more capacity in the same space. Rugged brass cages
make the 01E and 02E bearings suitable for underground applications and other
challenging environments.

The new design is now available in medium-duty and heavy-duty bearings with
bore sizes from 6.5 inches to 12 inches (160mm to 300mm). Typical applications
for these sizes include mining equipment (e.g. bucket wheel excavators,
crushers, stacker reclaimers), industrial fans and conveyors, and power

The medium-duty 01E and heavy-duty 02E Series, combined with the
extra-heavy-duty 03, high-speed 04 and compact 100 Series, make the Cooper
line of split roller bearings the most comprehensive in the industry.
