Polyurethane Castors Vs Rubber Castors

The most popular option in the material handling sector are rubber and polyurethane castors. They are routinely employed interchangeably, despite their distinct functions and so are commonplace on around 80% of industrial applications.

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

Load capacity/highest weight

Most likely one among the most important criteria of caster choice is identifying the maximum load. Polyurethane castors can ordinarily carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have incredibly thin threads in comparison to rubber casters, which boosts their load capacity. Polyurethane castors also are more immune to splitting and tearing.

Floor Protection & Marking

Common Rubber Castors are manufactured making use of Carbon Black Filler. Regretably, this Carbon Black will mark floors, specially wooden & tiled floors and it is therefore not suited to applications where floor marking Attributes are crucial.

Polyurethane However isn't going to generally mark flooring.

While Polyurethane is mostly blended with a colourant, the chemical make-up of the material locks the colour check here into the material and cannot leach or mark flooring surfaces.

Roll Resistance

Roll resistance is a vital aspect for ease of use. The lower the roll resistance, the less difficult it can be to maneuver the equipment. This raises operator comfort and ease and performance. In terms of minimizing roll resistance, two matters matter – consistency and hardness of the material.

Polyurethane castors are more uniform in nature than normal rubber as a consequence of their artificial composition. The material’s really 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 lose tread with time, whereas polyurethane 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 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 within the AUT website.
