Polyurethane Castors in Comparison with Rubber Castors

polyurethane castors

The preferred option 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 eighty% 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 concerns of caster choice is identifying the most load. Polyurethane castors can normally carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors might have extremely slim threads when compared with rubber casters, which raises their load capability. Polyurethane castors are also a lot more resistant to splitting and tearing.

Flooring Protection & Marking


Conventional Rubber Castors are produced working with Carbon Black Filler. Sadly, this Carbon Black will mark flooring, particularly wooden & tiled flooring and is as a result not suitable for applications exactly where ground marking properties are essential.

Polyurethane Conversely doesn't normally mark flooring.

Even though Polyurethane is usually 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 lower the roll resistance, the simpler it can be to maneuver the products. This raises operator convenience and performance. In relation to cutting down roll resistance, two things matter – consistency and hardness of the more info material.

Polyurethane castors are more standard in character than purely natural rubber because of their synthetic composition. The material’s very consistent texture supplies reliable amounts of rolling friction, causing reduced roll resistance.

Durability


Rubber castors provide a softer trip, However they don’t last as long as polyurethane castors. Rubber castor wheels get rid of tread with more info time, While polyurethane castor wheels have appreciably bigger resistance to wear and abrasion. more info Polyurethane castor wheels can endure nearly 3 times longer than rubber castor wheels under managed tests. Depending on the composition, polyurethane castors also have a tendency to outperform rubber castors when it comes to oil, grease, and chemical resistance.

As you are able to see, picking polyurethane castors is normally your best option. You are able to purchase polyurethane castors from the AUT website.
