Polyurethane Castors Versus Rubber Castors

polyurethane castors

The preferred choice in the material handling sector are rubber and polyurethane castors. They are often used interchangeably, regardless of their distinctive functions and 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


Probably one of The key factors of caster choice is analyzing 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 slim threads as compared to rubber casters, which will increase their load ability. Polyurethane castors will also be more resistant to splitting and tearing.

Ground Protection & Marking


Normal Rubber Castors are created utilizing Carbon Black Filler. Sad to say, this Carbon Black will mark floors, notably wood & tiled floors and it is therefore not appropriate for applications where by floor marking Attributes are crucial.

Polyurethane Alternatively won't generally mark flooring.

Although 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 get more info a crucial feature for ease of use. The less the roll resistance, the less complicated it is to move the tools. This boosts operator comfort and efficiency. In regards to reducing roll resistance, two items make a difference – consistency and hardness of the material.

Polyurethane castors tend to be more standard in character than natural rubber as a result of their synthetic composition. The material’s remarkably constant texture presents consistent levels of rolling friction, resulting in lowered roll resistance.

Sturdiness


Rubber castors give a softer journey, 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 as much as three times longer than rubber castor wheels under controlled testing. Based on the composition, polyurethane castors also often outperform rubber castors regarding oil, grease, and chemical resistance.

As you'll be able to see, picking out polyurethane castors is frequently your best option. You'll be able to buy polyurethane castors through the AUT website.
