Polyurethane Castors Versus Rubber Castors
The most popular choice in the material handling sector are rubber and polyurethane castors. They're routinely applied interchangeably, irrespective of their unique features and they are common on around eighty% of industrial applications.
But, what’s the difference between rubber and polyurethane castors and which must you consider using?
Load capability/maximum weight
Perhaps amongst The main considerations of caster choice is identifying the most load. Polyurethane castors can normally carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors may have extremely slim threads when compared with rubber casters, which increases their load capability. Polyurethane castors are also far more resistant to splitting and tearing.
Flooring Protection & Marking
Standard Rubber Castors are produced using Carbon Black Filler. However, this Carbon Black will mark flooring, specifically wood & tiled floors and is thus not ideal for applications where by floor marking properties are important.
Polyurethane On the flip side does not normally mark flooring.
Even though Polyurethane is generally combined 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 increases operator convenience and performance. When it comes to lowering roll resistance, two factors make any difference – consistency and hardness of the material.
Polyurethane castors tend to be more uniform in nature than normal rubber on account of their artificial composition. The material’s really consistent texture offers steady levels of rolling friction, leading to diminished roll resistance.
Longevity
Rubber castors present you with a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane castor wheels have considerably larger resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under controlled testing. With regards to polyurethane castors the composition, polyurethane castors also are likely to outperform rubber castors with regard to oil, grease, and chemical resistance.
As it is possible to see, deciding upon polyurethane castors is usually the only option. You are able to get polyurethane castors through the AUT website.
