The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are often utilized interchangeably, regardless of their distinctive functions and therefore are prevalent on close to 80% 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 factors of caster choice 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 can have incredibly skinny threads in comparison to rubber casters, which improves their load capability. Polyurethane castors are a lot more immune to splitting and tearing.
Flooring Protection & Marking
Standard Rubber Castors are made using Carbon Black Filler. Sad to say, this Carbon Black will mark floors, notably wooden & tiled floors and it is consequently not well suited for applications exactly where ground marking properties are essential.
Polyurethane Conversely will not frequently mark flooring.
Whilst Polyurethane is mostly blended with 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 a crucial check here function for ease of use. The smaller the roll resistance, the easier it learn more truly is to maneuver the products. This raises operator convenience and performance. In terms of cutting down roll resistance, two things matter – consistency and hardness of the material.
Polyurethane castors tend to be more standard in character than natural rubber as a result of their synthetic composition. The material’s remarkably constant texture provides constant levels of rolling friction, leading to diminished roll resistance.
Longevity
Rubber castors present you with a softer ride, but they don’t last as long as polyurethane castors. Rubber castor wheels drop tread with time, While polyurethane castor wheels have drastically better resistance to wear and abrasion. Polyurethane castor wheels can endure nearly 3 times longer than rubber castor wheels under managed tests. Depending on the composition, polyurethane castors also have a tendency to outperform rubber castors with regards to oil, grease, and chemical resistance.
As you'll be able to see, deciding on polyurethane castors is frequently get more info your best option. You'll be able to buy polyurethane castors with the AUT Web site.
