High density polymer rollers are the future in field conveyors. Major developments have been made - we supply polymer rollers in suspended idlers and returns, incorporated in our new field conveyor bays. Standard stock range includes suspended sets with our unique new safety handles in steel or polymer.

The characteristics of high density polymer rollers are:


  • High quality: The roller shell in manufactured from HDP (High Density Polymer) with impact resistant, acid resistant, anti-corrosion, anti-alkali in chemical water. The roller is assembled well with double cap bearings, in compliance with ISO standards.
  • Heavy rigid and high impact roller performance: Different from the steel roller the Canning synthetic roller has good impact and instauration. Strengthened frame offers the synthetic roller to the same rigidity as a steel roller.
  • Excellent waterproof and anti-dust: The Canning synthetic roller provides triple bearing protection. Seal rings prevent water and dust from entering into the inside of the roller. Special catchment groove utilising centrifugal force keeps the inside of the roller dry in all weather conditions. The patented triple labyrinth seals offer a 45% higher efficiency of preventing water and dust than traditional labyrinths.
  • Higher efficiency: Ejection body, homogeneous mass, good roundness, minimum roller factor, durable for high speed operation, power saving, noise free.
  • Light weight: The Canning synthetic roller is 55% lighter than traditional steel roller, suitable for small drive, head pulley and tail pulley, it can save ¼ cost for power and equipment cost.
  • Low maintenance cost: Long service life (guarantee for two years under normal operation), no lubrication oil needed, easy replacement, reduce maintenance labour and time to the minimum.
  • Specification: â—¦Tube: 102mm/127mm diameter x 8mm wall thickness
    â—¦Shaft: bright drawn mild steel.
