Regal Rexnord
Bulk Handling Components
Regal Rexnord bulk handling components are heavy - duty mechanical elements engineered for the rigorous demands of moving aggregates, ores, grains, minerals, and other bulk commodities in mining, cement, power - generation, and agricultural processing operations.This category encompasses bucket elevator components including head and boot shaft assemblies, elevator buckets, belt and chain fasteners, and take - up systems; screw conveyor components including helicoid and sectional flights, troughs, hanger bearings, and drive shafts; and belt conveyor bulk - handling elements including impact idlers, belt cleaners, skirt - board systems, and pulley lagging.Plant reliability engineers and maintenance managers in heavy industry select Regal Rexnord bulk handling components when they require components that can withstand 24 / 7 operation under abrasive dust, heavy shock loading, extreme temperatures, and the relentless wear that destroys commodity - grade components in weeks.Under the Rexnord, Link - Belt, and Falk brands, our bulk handling portfolio leverages metallurgical expertise — hardened wear surfaces, abrasion - resistant alloys, and specialized coatings — combined with application - specific geometric designs that maximize material flow, minimize hang - up, and extend component replacement intervals beyond industry norms.

Trusted by Industry Leaders
Abrasion - Resistant Wear Materials
Hardened alloy steels, ceramic - lined surfaces, and tungsten - carbide overlay options that extend bucket, flight, and liner life by 3x to 10x in abrasive aggregate and mineral - handling applications.
Impact - Idler Systems for High - Load Transfer Points
Specially designed roller assemblies with rubber cushion rings that absorb impact energy at belt loading zones, protecting belt carcasses from the damage that causes premature splice failure.
Engineered Bucket Profiles for Clean Discharge
Bucket geometries optimized by centrifugal - discharge modeling to ensure complete material evacuation at the head pulley — eliminating the carry - back that reduces capacity and creates housekeeping problems.
Hanger Bearing Configurations for Screw Conveyors
Sealed, relubricatable, and self - aligning hanger bearing designs that survive the contaminated, high - load environment inside screw - conveyor troughs without the weekly failures common with standard bearings.
Belt Fastener & Splice Kits
Mechanical and vulcanized splice solutions sized for specific belt ratings and pulley diameters, including stainless - steel fasteners for corrosive bulk materials like fertilizers and salts.
Modular Take - Up & Tensioning Systems
Gravity, screw, and hydraulic take - up units that maintain optimal belt or chain tension through varying load conditions and thermal expansion cycles, preventing the slip and tracking issues that cause unplanned downtime.
Bulk Handling Components for Mining & Aggregates
Mining and aggregate processing subjects conveying and elevating equipment to some of the most punishing conditions in any industry — abrasive silica dust that accelerates wear by an order of magnitude, impact loads from 24 - inch minus rock dumped from haul trucks, and 24 / 7 operation that leaves no windows for unplanned maintenance.Regal Rexnord bulk handling components are engineered specifically for this environment.Our bucket elevator systems for aggregate plants feature hardened lip and reinforced mounting - hole designs that survive the impact of sharp, abrasive stone.Screw conveyor flights for cement and fly - ash handling incorporate hard - faced outer edges that maintain close clearance to the trough, ensuring consistent volumetric efficiency even as the flight surface wears.Belt conveyor impact idlers and pulley lagging designed for the mining market use ceramic and rubber compounds that absorb the energy of primary - crusher discharge impact without the catastrophic failure modes of brittle materials.By specifying Regal Rexnord bulk handling components engineered for the specific material, tonnage, and duty cycle of the operation, aggregate and mining companies achieve the component life and maintenance intervals that make continuous production economically viable.
Bucket Elevator Component Selection & Maintenance
Optimal bucket elevator performance depends on correct component specification for the material characteristics and required throughput.For abrasive, heavy materials like crushed stone and clinker, ductile - iron or hardened - steel buckets with reinforced lips and vent holes(to release trapped air during filling) maximize both bucket life and volumetric fill efficiency.For lighter, free - flowing materials like grains and plastic pellets, fabricated - steel or polymer buckets with smooth, non - stick surfaces prevent product hang - up and reduce carry - back.Head and boot pulley lagging material selection — ceramic for high - tension, high - slip applications, rubber for moderate - duty general service — directly affects belt or chain traction and splice life.Regal Rexnord application engineers use material - properties databases and filling - discharge modeling to specify the optimal bucket shape, spacing, speed, and hardware for each bulk - material application, ensuring that the elevator achieves its design capacity with the lowest possible maintenance burden.
