Surface Rolls, Idlers, and Structure^Non-Current

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.

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.

The intelligent design and manufacturing technology provide long life, high reliability and superior performance.

Multiple configurations and roll material options provide maximum flexibility for all surface mining belt conveyors.

Roll technology utilizing two-piece tapered roller bearings and a reliable sealing system provides excellent performance in dirty and adverse mining conditions.

Multiple configurations and roll material options provide maximum flexibility for all surface mining belt conveyors.

The utilization of rubber discs provides additional wear capacity to the idler and also protects the conveyor belting in any mining conditions.

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.
