Polyurethane Castors Versus Rubber Castors

The most well-liked option in the material handling sector are rubber and polyurethane castors. They are commonly made use of interchangeably, irrespective of their unique functions and so are common on about 80% of industrial applications.

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

Load capability/highest weight

Most likely considered one of The main things to consider of caster choice is deciding the maximum load. Polyurethane castors can normally carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have very slim threads in comparison to rubber casters, which increases their load ability. Polyurethane castors also are a lot more resistant to splitting and tearing.

Floor Protection & Marking

Conventional Rubber Castors are made making use of Carbon Black Filler. Sadly, this Carbon Black will mark flooring, specially wooden & tiled flooring and it is as a result not ideal for applications where ground marking properties are crucial.

Polyurethane Then again will not generally mark flooring.

Although Polyurethane is generally blended with 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 aspect for ease of use. The smaller the roll resistance, the simpler it is to move the products. This will increase operator comfort and effectiveness. In terms of reducing roll resistance, two points matter – consistency and hardness of the material.

Polyurethane castors are more standard in nature than normal rubber as a consequence of their artificial composition. The material’s really consistent texture provides constant levels of rolling friction, leading to lowered roll resistance.

Toughness

Rubber castors give a softer journey, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels polyurethane castors 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. Depending polyurethane castors on the composition, polyurethane castors also have a tendency to outperform rubber castors with regards to oil, grease, and chemical resistance.

As you are able to see, picking polyurethane castors is normally the best choice. You can order polyurethane castors within the AUT Web-site.
