RCK Ultra Primary Impact Resistant

RCK Ultra Primary Impact Resistant belt was designed for the heaviest/roughest HIGH IMPACT applications. Primary and secondary conveyors are notorious for sharp and unforgiving rocks coming straight from the crusher jaws. They are doing their best to penetrate the top covers of any belt. The Ultra Primary M Grade rubber compound is ready for this attack whilst also giving great abrasion resistance. Covers are thicker with 8MM and 10MM top covers but we have added and extra breaker ply into the top cover. This ply is designed to deflect sharp objects that penetrate the top rubber covers.
