Polyurethane Castors Versus Rubber Castors

polyurethane castors

The most well-liked option in the material handling sector are rubber and polyurethane castors. They're frequently employed interchangeably, in spite of their distinctive capabilities and they are commonplace 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 one of the most important considerations of caster selection is determining the most load. Polyurethane castors can ordinarily carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors may have quite skinny threads when compared with rubber casters, which will increase their load capacity. Polyurethane castors can also be more immune to splitting and tearing.

Flooring Protection & Marking


Regular Rubber Castors are manufactured applying Carbon Black Filler. Sad to say, this Carbon Black will mark floors, especially wood & tiled floors and is thus not suited to applications exactly where ground marking properties are important.

Polyurethane Conversely isn't going to usually mark flooring.

Even though Polyurethane is mostly mixed using a colourant, the chemical make-up of the material locks the colour into the material and cannot leach or mark flooring surfaces.

Roll Resistance


Roll resistance is a vital function for simplicity of use. The lower the roll resistance, the less complicated it truly is to maneuver the gear. This improves operator convenience and performance. In regards to decreasing roll resistance, two matters matter – consistency and hardness of the material.

Polyurethane castors tend to be more uniform in nature than pure rubber due to their artificial composition. The material’s highly consistent texture delivers constant levels of rolling friction, causing decreased roll resistance.

Toughness


Rubber castors present you with a softer ride, Nevertheless they don’t last as long as polyurethane castors. Rubber castor wheels reduce tread with time, whereas polyurethane castor wheels have drastically bigger resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under managed tests. Based on the composition, polyurethane castors also are likely to outperform rubber castors in terms of oil, grease, and chemical check here resistance.

As you are able to see, deciding on polyurethane castors is frequently the only option. You can order polyurethane castors through the AUT Web site.
