Polyurethane Castors V Rubber Castors

The preferred choice in the material handling sector are rubber and polyurethane castors. They're regularly employed interchangeably, irrespective of their distinct capabilities and so are prevalent on close to 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 deciding the maximum 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 with rubber casters, which increases their load capability. Polyurethane castors are also a lot more immune to splitting and tearing.

Flooring Protection & Marking

Typical Rubber Castors are produced working with Carbon Black Filler. Sadly, this Carbon Black will mark flooring, particularly wooden & tiled flooring and it is consequently not well suited for applications where flooring marking Attributes are important.

Polyurethane Then again would not usually mark flooring.

Although Polyurethane is normally mixed 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 a crucial feature for ease of use. The less the roll resistance, the less complicated it is to move the gear. This boosts operator consolation and efficiency. In relation to lessening roll resistance, two things matter – consistency and hardness of the material.

Polyurethane castors are more standard in character than pure rubber thanks to their synthetic composition. The material’s extremely consistent texture gives regular amounts of rolling friction, leading to minimized roll resistance.

Longevity

Rubber castors present you with a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane read more castor wheels have considerably greater 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 with regards to oil, grease, and chemical resistance.

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