Innovation Starts at the Roller

20"roller next to CEMA maximum size 219mm

Conventional conveyor systems waste energy through 

small rollers, poor materials, and friction-heavy designs


Big Roller™ reduces system losses at the source with 

larger diameters

 lighter materials and 

lab-validated design principles

The Engineering Behind the Advantage

 🌀IRR Reduction Up to 50% lower indentation rolling resistance from contact geometry

🔧Bearings 80% less Rim Drag friction and extended bearing life / increased load capacities

⚙️Lab-Tested Materials 22x improved wear resistance compared to HDPE + Glass shells

📏Precision Tolerances T.I.R. < 0.2 mm, G16 dynamic balance class, machined fabrications

How We Innovate

 

Big Roller™ applies a systematic framework across every product line:

Technology Readiness Levels (TRLs) – NASA aligned progression from concept to deployment
Market & Adoption Readiness (MRL/ARL) – Evaluating regulatory and operational fit
Commercial Readiness Index (CRI) – Financial metrics to track performance
Lean Canvas & Unleashed Zone Diagnostics – Business model validation for scalable deployment


We don’t guess. We test, measure, and improve — at every step

Better by Design – and by Material

We scoured the global idler supply chain to source the best roller designs. Our extensive investigations led us to a manufacturer of cast Nylon materials that outperforms in terms

  • Mechanical strength and fatigue endurance limits required at 20" diameters
  • Lightweight ≤ 20 kg
  • High-wear endurance
  • ISO 9001 certified

Validated by Industry Leaders

✔️ Minerals Research Institue of WA funded research

✔️ TUNRA Bulk Solids: 

  • IRR AS 1333 (2024) Type II tests to AS 1334.17 (2017)
  • Rim drag, breakaway forces
  • Shell to end cap/bearing housing load – resistance to pressing out
  • Dust and Water Ingress SANS 1313-3
  • T.I.R. / M.I.S.
  • Dynamic Balance to ISO 1940
  • Self-Noise
