Polyurethane Castors Compared to Rubber Castors

The preferred option in the material handling sector are rubber and polyurethane castors. They are often utilised interchangeably, in spite of their distinctive capabilities and they are commonplace on close to eighty% of industrial applications.

But, what’s the distinction between rubber and polyurethane castors and which must you consider using?

Load capacity/maximum weight

Perhaps one of The key concerns of caster selection is determining the most load. Polyurethane castors can usually carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors might have incredibly skinny threads as compared to rubber casters, which improves their load capacity. Polyurethane castors are also extra immune to splitting and tearing.

Floor Protection & Marking

Standard Rubber Castors are created working with Carbon Black Filler. However, this Carbon Black will mark floors, particularly wood & tiled floors and it is for that reason not appropriate for applications exactly where ground marking properties are important.

Polyurethane Conversely isn't going to usually mark flooring.

Even though Polyurethane is usually blended 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 a vital feature for simplicity of use. The lower the roll resistance, the less difficult it really is to get more info maneuver the equipment. This boosts operator consolation and efficiency. In regards to reducing roll resistance, two issues make a difference – consistency and hardness of the material.

Polyurethane castors tend to be more standard in character than purely natural rubber because of their synthetic composition. The material’s very consistent texture supplies reliable amounts of rolling friction, causing lessened roll resistance.

Longevity

Rubber castors offer 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 testing. With regards to 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 view more site.
