The most well-liked choice in the material handling sector are rubber and polyurethane castors. They're routinely applied interchangeably, irrespective of their distinct capabilities and so are prevalent on close to 80% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which should you think about using?
Load capacity/highest weight
Probably one of The key issues of caster selection is deciding the maximum load. Polyurethane castors can commonly carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors might have really slim threads when compared to rubber casters, which raises their load capability. Polyurethane castors can also be far more resistant to splitting and tearing.
Flooring Protection & Marking
Conventional Rubber Castors are produced working with Carbon Black Filler. Sadly, this Carbon Black will mark flooring, particularly wooden & tiled flooring and is as a result not suitable for applications exactly where ground marking properties are essential.
Polyurethane On the flip side does not typically mark flooring.
Even though Polyurethane is generally mixed get more info using a colourant, the chemical make-up of the material locks the colour into the material and can't leach or mark flooring surfaces.
Roll Resistance
Roll resistance is an important function for simplicity of use. The smaller the roll resistance, the less complicated it really is to move the tools. This improves operator comfort and effectiveness. When it comes to decreasing roll resistance, two points make any difference – consistency and hardness of the material.
Polyurethane castors tend to be more uniform in nature than all-natural rubber on account of their artificial composition. The material’s remarkably constant texture provides constant levels of rolling friction, resulting in lowered roll resistance.
Toughness
Rubber castors give a softer journey, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels reduce tread with time, Whilst polyurethane castor wheels have significantly higher resistance to wear and abrasion. Polyurethane castor wheels can survive up to three times longer than rubber castor wheels under controlled testing. According to get more info the composition, polyurethane castors also are inclined to outperform rubber castors with regard to oil, grease, and chemical resistance.
As you'll be able to see, picking out polyurethane castors is frequently the only option. You'll be able to buy polyurethane castors through the AUT Web site.
