Polyurethane Castors Compared to Rubber Castors

The preferred choice in the material handling sector are rubber and polyurethane castors. They are frequently used interchangeably, despite their unique functions and 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/maximum weight

Potentially one among the most important considerations of caster choice is identifying the most load. Polyurethane castors can commonly carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors might have extremely slim threads when compared to rubber casters, which raises their load ability. Polyurethane castors can also be far more resistant to splitting and tearing.

Flooring Protection & Marking

Conventional Rubber Castors are produced applying Carbon Black Filler. Regrettably, this Carbon Black will mark flooring, especially wood & tiled flooring and is for that reason not suitable for applications wherever ground marking properties are essential.

Polyurethane Conversely doesn't normally mark flooring.

Even though Polyurethane is generally combined by 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 an important attribute for simplicity of use. The smaller the roll resistance, the easier it truly is to maneuver the products. This increases operator convenience and effectiveness. With regards to minimizing roll resistance, two matters matter – consistency and hardness of the material.

Polyurethane castors are more uniform in nature than pure rubber thanks to their read more artificial composition. The material’s highly consistent texture offers steady levels of rolling friction, leading to minimized roll resistance.

Longevity

Rubber castors present you with 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 larger resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under controlled testing. Dependant upon the composition, polyurethane castors also tend to read more outperform rubber castors in terms of oil, grease, and chemical resistance.

As you can see, selecting polyurethane castors is usually the best choice. It is possible to get polyurethane castors within the AUT Web-site.
