HCD Synthetic HDPE HD Rollers

New Zealand Conveyor conditions are unique due mainly to the amount of wet weather our country experiences. Dust and dirt driven into roller bearings and seals in these wet and mucky conditions is a well-known issue in the Conveyor industry. HCD Synthetic HDPE HD Rollers must be designed with this problem in mind.    This type of problem is common in these industries:

  • Fertiliser
  • Sand Plants
  • Hard Rock Quarries
  • Coal Plants
  • Iron Ore
  • Timber mills
  • Gold Mines

Quality is the key to all conveyor rollers and we have this at the top of our list when selecting our manufacturers and roller designs. Tight quality assurance procedures are inspected by us yearly to ensure our quality is the best and we can guarantee consistent and optimum roller performance.

KEY POINTS OF DIFFERENCE – HCD Synthetic HDPE HD Rollers

DIAMETER SHAFT SIZE BEARING TYPE SEAL TYPE END CAP BELT WIDTHS TYPES
114MM 20MM 6204ZZ TRIPLE LABARINTH RECESSED 450, 600, 750, 900, 1050 & 1200MM STEEL, SYNTHETIC

 

  • 6204ZZ BEARING – This deep groove bearing has a ZZ DOUBLE STEEL SHIELD which is very rare for a roller in New Zealand. This gives the bearing double protection against fugitive material reducing the chances of contamination and damage to the bearings integrity
  • TRIPLE LABARINTH SEAL – The bearing is also protected by a German designed seal with 3 levels of protection. Additionally the seal is packed with grease creating an impenetrable barrier to fugitive dust, dirt and water.
  • RECESSED END CAPS – This is unique to the HCD Roller. Mis-tracking belts are notorious for sideways movement on trough and return rollers. The causes end caps that are welded to the edges of belts to fail prematurely as the belts wear through the welds. The result is disastrous as the roller tube will then drop out leaving end caps exposed and these will cut through the belts quickly.

Stock is carried in many of our HCD branches throughout New Zealand in all the standard sizes
