Polyurethane Castors in Comparison to Rubber Castors

The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are often used interchangeably, despite their unique functions and therefore are commonplace on about 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

Possibly amongst The main factors of caster choice is deciding the maximum load. Polyurethane castors can ordinarily carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors might have quite thin threads as compared to rubber casters, which will increase their load capacity. Polyurethane castors will also be more immune to splitting and tearing.

Floor Protection & Marking

Common Rubber Castors are manufactured employing Carbon Black Filler. Unfortunately, this Carbon Black will mark flooring, particularly wooden & tiled flooring and is for that reason not suitable for applications wherever ground marking properties are very important.

Polyurethane However isn't going to generally mark flooring.

While Polyurethane is normally mixed 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 crucial function for simplicity of use. The smaller the roll resistance, the easier it truly is to maneuver the products. This raises operator convenience and performance. With regards to minimizing roll resistance, two matters matter – consistency and hardness of the material.

Polyurethane castors are more standard in character than purely natural rubber because of their synthetic composition. The material’s hugely constant texture delivers dependable levels of here rolling friction, resulting in lowered roll resistance.

Toughness

Rubber castors give a softer experience, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane castor wheels have considerably larger resistance to wear and abrasion. Polyurethane castor wheels can survive approximately three times longer than rubber castor wheels under controlled screening. Dependant upon the composition, polyurethane castors also usually view more outperform rubber castors in terms of oil, grease, and chemical resistance.

As you can get more info see, choosing polyurethane castors is normally your best option. You are able to purchase polyurethane castors through the AUT website.
