Polyurethane Castors in Comparison with Rubber Castors

The most popular choice in the material handling sector are rubber and polyurethane castors. They are commonly made use of interchangeably, regardless of their distinct features and are prevalent on close to eighty% of industrial applications.

But, what’s the distinction between rubber and polyurethane castors and which must you consider using?

Load capacity/maximum weight

Perhaps amongst The key criteria of caster choice is analyzing the maximum load. Polyurethane castors can typically carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors can have pretty slim threads as compared to rubber casters, which boosts their load capability. Polyurethane castors can also be more immune to splitting and tearing.

Flooring Protection & Marking

Regular Rubber Castors are created working with Carbon Black Filler. Sadly, this Carbon Black will mark flooring, significantly wooden & tiled floors and it is therefore not suited to applications where by floor marking properties are very important.

Polyurethane on the other hand will not commonly mark flooring.

Whilst Polyurethane is usually combined 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 characteristic for simplicity of use. The smaller the roll resistance, the view more less complicated it is to move the gear. This boosts operator consolation and efficiency. In terms of minimizing roll resistance, two matters matter – consistency and hardness of the material.

Polyurethane castors are more uniform in nature than all-natural rubber on account of their artificial composition. The material’s really consistent texture gives regular amounts of rolling friction, leading to minimized roll resistance.

Toughness

Rubber castors present you with a softer experience, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels reduce tread with time, Whilst polyurethane castor wheels have noticeably higher resistance to wear and abrasion. Polyurethane castor wheels can endure up to 3 times longer than rubber castor wheels under managed tests. Depending upon the composition, polyurethane castors also tend to outperform rubber castors in terms of oil, grease, and chemical resistance.

As you can see, selecting polyurethane castors is usually the only option. It is possible to buy polyurethane castors with the AUT Web site.
