High temperature applications requiring wheels like rotary baking ovens, powder coating ovens and smoke houses call for tough materials.
They must not only withstand the heat, but also load and impact in those conditions.
Traditional materials used in the manufacture of wheels for these applications include machined steel, cast iron, fibreglass reinforced nylon and resin (sometimes known as phenolic resin or Bakelite).
All these materials are very hard – and unforgiving – especially on prepared floors and surfaces.
Constant use of these hard wheels not only abrades and damages the flooring, but can it transmit shock and vibration through the trolley causing fatigue and failure of the trolley parts.
Shaking and rattling trolleys can also cause annoying noise for workers and shoppers.
A more recent development is a high temperature tolerant rubber tyre compound available from QHDC Australia, that will handle a constant 260°C or a maximum of 300°C intermittently.
Moulded on to an aluminium centre hub and assembled with sealed precision bearings these wheels can be mounted on an axle or assembled into castor frames that can be bolted or welded to trolleys.
The wheels are now available in the most common size (100mm x 36mm with an 8mm bore) with larger sizes to be released soon.
Options include stainless ball bearings and stainless castor frames – all factory assembled using high temperature grease.
