Rollers & Idlers

West River Conveyors offers a wide range of steel and HDPE rollers and idlers designed to keep your operations running smoothly, so you can focus on productivity instead of conveyor performance.

Our lineup includes CEMA B, C, D, E, and F idlers to meet the needs of both overland and underground applications. We provide a variety of configurations, including rigid rail idlers, inline structures, catenary idler structures, transitional idlers, and other specialty-engineered solutions. These options are available for belt widths ranging from 24 to 72 inches, with additional sizes offered to fit your specific requirements.

Bearing integrity, can durability, low shaft run-out, and effective seals are the four major components that any good conveyor roller and idler should deliver. Turn to our line of products to achieve these features for seamless conveyor operation.

Underground salt conveyor with corrosion-resistant HDPE rollers

Steel & HDPE Rollers & Idlers for Peak Performance

Steel tube rollers are the most common types of idlers that you’ll find on conveyors in the mining industry because they are designed for heavyweight applications. However, HDPE rollers are becoming increasingly popular in harsh, high-moisture environments due to their corrosion resistance capabilities. WRC offers both steel and HDPE idlers and all of our idlers are designed to meet or exceed the load limits established by CEMA.

If your conveyor is working in demanding applications and needs to conform to CEMA standards, West River can provide:

  • Industry-leading idler brands with West River’s frame workmanship
  • Idlers and conveyor structures that are ideal for harsh mining environments
  • Idlers that are best for underground conveyor applications
  • Idlers that utilize the best ball-bearing technology
  • Idlers that have low Total Indicated Runout (TIR)
  • Idlers that have superior sealing systems

West River Conveyors: Where Strength & Reliability Meet

West River Conveyors offers a wide selection of rollers and idlers in various types and sizes to suit your application, all sourced from trusted, high-quality brands at fair prices. Our knowledgeable representatives are ready to assist you in finding the best solution for your application. Contact us for expert guidance and support.
