The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are frequently used interchangeably, despite their unique attributes and are prevalent on close to eighty% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which must you think about using?
Load capability/highest weight
Potentially one among The key issues of caster selection is analyzing the maximum load. Polyurethane castors can ordinarily carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors might have quite slim threads when compared to rubber casters, which raises their load ability. Polyurethane castors can also be far more resistant to splitting and tearing.
Flooring Protection & Marking
Conventional Rubber Castors are produced applying Carbon Black Filler. Regrettably, this Carbon Black will mark flooring, particularly wood & tiled flooring and is for that reason not suitable for applications wherever ground marking properties are essential.
Polyurethane Conversely doesn't check here normally mark flooring.
Even though Polyurethane is generally combined by 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 attribute for simplicity of use. The smaller the roll resistance, the easier it truly is to maneuver the products. This raises operator convenience and performance. When it comes to lowering 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 really constant texture provides constant levels of rolling friction, leading to minimized roll resistance.
Longevity
Rubber castors present you with a softer ride, but they don’t last as long as polyurethane castors. Rubber castor wheels shed tread with time, whereas polyurethane castor wheels have substantially larger resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under controlled screening. With regards to get more info the composition, polyurethane castors also are likely to outperform rubber castors concerning oil, grease, and chemical resistance.
As it is possible to see, deciding upon polyurethane castors will likely be the only option. You'll be able to buy polyurethane castors with the AUT Web site.
