Polyurethane Castors Vs Rubber Castors

The preferred option in the material handling sector are rubber and polyurethane castors. They are regularly utilized interchangeably, despite their unique attributes and they are widespread on around eighty% of industrial applications.

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

Load capability/highest weight

Probably one of The main concerns of caster choice is figuring out the most load. Polyurethane castors can generally carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors can have incredibly thin threads in comparison to rubber casters, which boosts their load capacity. Polyurethane castors will also be extra resistant to splitting and tearing.

Ground Protection & Marking

Standard Rubber Castors are made applying Carbon Black Filler. Regrettably, this Carbon Black will mark flooring, particularly wooden & tiled flooring and it is consequently not well suited for applications where flooring marking Attributes are crucial.

Polyurethane Alternatively won't generally mark flooring.

While Polyurethane is mostly blended by 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 an important attribute for simplicity of use. The smaller the roll resistance, the easier it truly is to maneuver the tools. This improves operator comfort and efficiency. When it comes to decreasing roll resistance, two factors make any difference – consistency and hardness of the material.

Polyurethane castors tend to be more standard in polyurethane castors character than natural rubber due to their synthetic composition. The material’s very constant 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 considerably greater resistance to wear and abrasion. Polyurethane castor wheels can survive as much as three times longer than rubber castor wheels under controlled tests. According to the composition, polyurethane castors also are inclined to outperform rubber castors regarding oil, grease, and chemical resistance.

As you'll be able to see, deciding on polyurethane castors is often your best option. You are able to order polyurethane castors from the AUT Web-site.
