Steel Rolls

The Cat roll design is the result of over two years of design and engineering effort and represents new technology in idler designs. The shaft end configuration of the Cat roll allows retrofitting capabilities into virtually any frame with a unique retrofit adaptor.


Electronic Quality Tracking: An Industry First

Caterpillar is the first idler manufacturer to offer individual serialized rolls as a standard. Each roll can easily be identified by manufacture date, allowing accurate monitoring of roll life.


Surface Belt Structure Configurations

All Cat Surface Belt Structure conforms to CEMA (Conveyor Equipment Manufacturers Association) standards.


Carrying Idlers

Cat In-Line Carrying Idlers are designed for the rugged and sometimes adverse conditions that exist in all surface mining industries.


Impact Idlers

Cat In-Line Impact Idlers are ideal for loading and high-impact belt conveyor applications and conditions.


Return Idlers

Cat Return Idlers are designed for the rugged and sometimes adverse conditions that exist in all surface mining industries.


Rubber Disc Return Idlers

Rubber Disc Return Idlers are ideal for critical return belt conditions in conveyor applications.


Replacement Steel, EXALON®, and Rubber Disc Rolls

Roll material options provide superior performance in any conditions—wet, dry, clean, dirty, abrasive and corrosive environments.


Steel Rolls - Surface Applications

Diameters:

  • 4", 5" and 6" CEMA C or D (load capacity, 30,000 - 60,000 hrs.)
  • 6" and 7" CEMA E (load capacity, 60,000 hrs.)


EXALON® Rolls

Cat EXALON® rolls are made of a proprietary high-molecular-weight polyethylene (HMWPE) and are available in CEMA C, D and E class ratings. While steel rolls are effective in most bulk material-handling applications, some applications benefit from the use of the EXALON® roll.


A Commitment to the Mining Industry

As the demand for commodities grows, mining companies need a partner to support them in their efforts. Caterpillar is committed to being that partner.
