Our end cap is designed for increased strength and a close fit to the deflector cap. Every roll is equipped with a self-lubricating system. Our automated assembly process includes three separate, metered grease inputs to ensure every roll has plenty of grease for a lifetime of trouble-free operation. The Idler PAL™ bearing cavity design allows for extra lubricant capacity, which is unmatched in the industry and assures that the grease stays in the bearing.
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. » Learn More
Each roll is test run, ensuring complete grease distribution throughout the bearings and seals. Each shaft end is coded at the time of assembly with the day of the year, production year, and an individual serial number. In addition, automatic data recording of rotational torque, TIR (Total Indicated Runout) and the bearing play of each individual roll is tied to the serial number.
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. » Learn More

Applications with environments that are highly corrosive, abrasive, wet and have a tendency for material buildup are ideal for EXALON® rolls. This roll offers balanced, vibration-free running. Cat EXALON® rolls are tube-based, with higher concentricity further enhanced by final machining (poly-body) for reduced belt wear. These fully conductive rolls are MSHA-certified as safe for underground use. They have two certifications: IC-56/1 – flame-resistant and IC-56/2 – flame-resistant and static dissipating. EXALON® rolls can also be retrofitted into virtually any frame and come in custom sizes.
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. » Learn More
