Polyurethane Castors in Comparison with Rubber Castors

The most well-liked choice in the material handling sector are rubber and polyurethane castors. They're commonly utilised interchangeably, no matter their distinctive characteristics and therefore are commonplace on about eighty% of industrial applications.

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

Load capability/maximum weight

Perhaps considered one of the most important considerations of caster choice is figuring out the most load. Polyurethane castors can typically carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors can have pretty thin threads in comparison to rubber casters, which boosts their load capacity. Polyurethane castors will also be more resistant to splitting and tearing.

Ground Protection & Marking

Regular Rubber Castors are made utilizing Carbon Black Filler. However, this Carbon Black will mark flooring, specifically wood & tiled floors and is thus not ideal for applications wherever ground marking properties are essential.

Polyurethane On the flip side doesn't normally mark flooring.

Even though Polyurethane is generally 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 a crucial function 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 regards to lessening roll resistance, two issues make a difference – consistency and hardness of the material.

Polyurethane castors are more standard in character than pure rubber thanks to their synthetic composition. The material’s highly consistent texture offers steady levels of rolling friction, leading to diminished 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 polyurethane castors with time, Whilst polyurethane castor wheels have significantly higher resistance to wear and abrasion. Polyurethane castor wheels can survive up to three times longer than rubber castor wheels under managed tests. Based on the composition, polyurethane castors also often outperform rubber castors with regards to oil, grease, polyurethane castors and chemical resistance.

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