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.


Underground Belt Structure Configurations

A Cat Floor-Mounted Structure can be configured with either the return rolls mounted in floor stands or in drop brackets attached to channel rails. Both floor-mounted and roof-hung structures feature the patented EZEE-LOC™ rail connections for quick installations.


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.
