Polyurethane Castors in Comparison to Rubber Castors

polyurethane castors

The preferred option in the material handling sector are rubber and polyurethane castors. They're routinely applied interchangeably, in spite of their distinct features and so are common on close to eighty% of industrial applications.

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

Load capability/maximum weight


Potentially one among the most important things to consider of caster selection is pinpointing the maximum load. Polyurethane castors can generally carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors can have incredibly thin threads in comparison with rubber casters, which improves their load capability. Polyurethane castors are much more immune to splitting and tearing.

Floor Protection & Marking


Typical Rubber Castors are manufactured working with Carbon Black Filler. Unfortunately, this Carbon Black will mark flooring, particularly wooden & tiled flooring and it is as a result not well suited for applications exactly where flooring marking Attributes are essential.

Polyurethane On the flip side does not typically mark flooring.

Even though Polyurethane is generally 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 more info resistance, the easier it truly is to maneuver the products. This increases operator convenience and effectiveness. When it comes to decreasing roll resistance, two factors make any difference – consistency and hardness of the material.

Polyurethane castors tend to be more uniform in nature than all-natural rubber on account of their artificial composition. The material’s really consistent texture provides steady levels of rolling friction, leading to diminished roll resistance.

Toughness


Rubber castors present you with a softer trip, Nevertheless they don’t last as long as polyurethane castors. Rubber castor wheels eliminate tread with time, Whilst polyurethane castor wheels have noticeably bigger resistance to wear and abrasion. Polyurethane castor wheels can endure up to 3 times longer than rubber castor wheels under managed tests. Based on the composition, polyurethane castors also often outperform rubber castors regarding oil, grease, and chemical resistance.

As you'll be able to see, deciding on polyurethane castors is often your best option. You are able to purchase polyurethane castors through the AUT website.
