31000 Series CEMA-C Idlers – Testing & Performance
31000 Series CEMA-C Idlers – Testing & Performance
Proven performance. Built for demanding conditions.
At Nordstrong, our commitment to quality goes beyond design and innovation. We put our patent-pending 31000 Series CEMA-C Idlers through rigorous in-house testing to ensure durability, safety, and performance in real-world applications.
Explore the videos below to see how our idlers perform under axial and radial load, in wet conditions, and in conductivity testing.
Pull Test – Withstanding Axial Load
This test simulates real-world axial forces that occur in bulk material handling applications to validate the durability of our patent-pending design.
Test Highlights: ✔ Withstood up to 3,200 lbf before end bell separation ✔ Performed in extreme cold at -35°C, withstanding 1,000 lbf ✔ Built with a one-piece end bell, engineered for strength and longevity
Radial Load Test – Exceeding CEMA Requirements
This test demonstrates the 31000 Series Idler’s ability to handle radial loads well beyond industry standards. By applying controlled downward force, we validate the structural strength of our idler design in demanding bulk handling conditions.
Test Highlights: ✔ CEMA Requirement: 900 lbf ✔ Nordstrong Result: Withstood over 4,000 lbf without failure ✔ Precision-engineered system built for long-term performance and durability
Conductivity Test – Ensuring Safe Static Discharge
In environments where dust and fine particles are present, static electricity can pose a serious explosion hazard. That’s why the 31000 Series Idler is equipped with a grounding wire to eliminate static buildup and improve operational safety.
Test Highlights: ✔ Measured Ground Resistance: Less than 5 ohms, meeting NFPA recommendations ✔ Complies with NFPA and NEC grounding standards ✔ Reduces static discharge risk in dust-prone and explosive environments
Water Submersion Test – Proving Sealing Integrity
Water ingress can compromise idler performance, shorten bearing life, and increase maintenance. To validate the sealing strength of the 31000 Series Idler, we conducted a long-term water submersion test to simulate harsh, moisture-rich environments.
Test Highlights: ✔ Half of an idler roll submerged in water for 30+ days ✔ No moisture penetration – interior remained completely dry ✔ Sealed-for-life bearing system designed for extreme environmental protection
