Polyurethane Castors Compared to Rubber Castors

The preferred option in the material handling sector are rubber and polyurethane castors. They are often employed interchangeably, despite 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 should you consider using?

Load capacity/highest weight

Potentially amongst The key criteria of caster choice is analyzing the maximum load. Polyurethane castors can normally carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have extremely slim threads in comparison with rubber casters, which raises their load capacity. Polyurethane castors are far more resistant to splitting and tearing.

Floor Protection & Marking

Conventional Rubber Castors are made making use of Carbon Black Filler. Sadly, this Carbon Black will mark flooring, notably wooden & tiled flooring and is therefore not suitable for applications wherever floor marking Attributes are essential.

Polyurethane on the other hand won't typically mark flooring.

Even though Polyurethane is mostly mixed using a colourant, the chemical make-up of the material locks the colour into the material and cannot 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 is to maneuver the products. This will increase operator consolation and effectiveness. In terms of reducing roll resistance, two factors make any difference – consistency and hardness of the material.

Polyurethane castors are more standard in get more info character than all-natural rubber thanks to their synthetic composition. The material’s hugely constant texture offers regular amounts of rolling friction, resulting in diminished roll resistance.

Longevity

Rubber castors offer a softer trip, Nevertheless they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane castor wheels have drastically bigger resistance to wear and abrasion. Polyurethane castor wheels can survive as much as three times longer than rubber castor wheels under managed tests. According to the composition, polyurethane castors also are likely to outperform rubber castors in terms of oil, grease, and chemical resistance.

As you are able to see, deciding on polyurethane castors is frequently the only option. You can order polyurethane castors from the AUT website.
