In addition to its world-class steel rolls, Caterpillar also offers a highly successful range of CEMA C, D, and E class rolls made of a proprietary high-molecular-weight polyethylene (HMWPE). This product is called EXALON®. While steel rolls are effective in most bulk material-handling applications, some applications benefit from the use of the EXALON® roll product. Applications in environments that are highly corrosive, abrasive, and wet, as well as having a tendency for material buildup on the roller, are ideal for the EXALON® roll and its additional features and benefits. »Learn More
Smooth operators
Tube-based with higher concentricity further enhanced by final machining (poly-body) for reduced belt wear, the EXALON® roll offers balanced, vibration-free running. »Learn More
Versatile and low maintenance
EXALON® rolls can be retrofitted to any frame – even those of competitors. »Learn More

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.

Custom sizes can be ordered for special applications. EXALON® heads are installed using a unique “spin-welding” method, creating a single-piece roll construction.
Versatile and low maintenance
EXALON® rolls can be retrofitted to any frame – even those of competitors. »Learn More
Upon acceptance, each idler roll is then permanently marked with a serial number and the date of manufacture.
Tested for quality
All Cat rolls – EXALON® and steel – are processed through an automated assembly system that tests and records rotational torque, total indicator run-out, and axial end play. »Learn More
Corrosion-proof: Since they are made of HMWPE, EXALON® rolls are not subject to corrosion.
Sound dampening: Noise is reduced by up to 20%, particularly in underground applications.
Resistance to material buildup: The smooth, non-adhesive HMWPE surface resists material buildup.
Cost-efficient: EXALON® offers cost savings through extended life, reduced downtime, longer replacement intervals, and reduced belt damage.
Versatile: The entire EXALON® product line can be produced to fit any existing manufacturer’s top-side and return-frame assemblies.
EXALON® benefits at a glance
MSHA-certified: Certified for underground use: IC-56/1 – flame-resistant, and IC-56/2 – flame-resistant and static dissipating.
Longer shelf life: EXALON® rolls last two to three times longer than steel rolls in highly corrosive and/or highly abrasive environments.
Reduced belt damage: The smooth PE surface minimizes belt friction and wear and acts as a slider bar in the event of a bearing seizure. The all-PE body means there are no sharp “pizza cutter” edges.
Lighter weight: EXALON® rolls are 20–30% lighter than equivalent steel rolls.
