Split Roller Bearings are engineered for long life, capacity.

Press Release Summary:

Bearings of medium-duty 01E and heavy-duty 02E Series are completely split to shaft, eliminating need to disassemble all components on shaft for service or replacement. Interchangeable with Cooper 01 and 02 Series bearings, 01E and 02E bearings have internal geometry that promotes L10 life expectancy as well as radial and axial load ratings. With brass cages that accommodate underground applications and challenging environments, bearings are available with bore sizes from 6.5–12 in.

New Cooper Bearings Raise the Bar for Capacity, Long Life

NORFOLK, VA… 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 L10 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 L10 life extends uptime even further, with longer intervals between replacement.

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 generation.

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.
