Polyurethane Castors Versus Rubber Castors

The most well-liked option in the material handling sector are rubber and polyurethane castors. They're commonly utilised interchangeably, no matter their distinctive functions and are prevalent on close to 80% of industrial applications.

But, what’s the distinction between rubber and polyurethane castors and which should you think about using?

Load capacity/highest weight

Perhaps considered one of the most important criteria of caster selection is determining the maximum 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 produced 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 important.

Polyurethane Alternatively won't generally mark flooring.

While Polyurethane is mostly blended with 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 element for simplicity of use. The lower the roll resistance, the easier it truly is to maneuver the products. This improves operator ease and comfort and effectiveness. On the subject of decreasing roll resistance, two items make a difference – consistency and hardness learn more of the material.

Polyurethane castors tend to be more standard in character than purely natural rubber because of their synthetic composition. The material’s extremely consistent texture gives regular amounts of rolling friction, leading to diminished roll resistance.

Toughness

Rubber castors give a softer experience, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels reduce tread with time, Whilst polyurethane castor wheels have significantly higher resistance to wear and abrasion. Polyurethane castor wheels can survive up to 3 times longer than rubber castor wheels under managed tests. Based on the composition, polyurethane castors also often outperform rubber castors with regards to oil, grease, and chemical resistance.

As you are able to see, choosing polyurethane castors is generally the best choice. You can get polyurethane castors within the AUT Web site.
