Polyurethane Castors V Rubber Castors

polyurethane castors

The preferred choice in the material handling sector are rubber and polyurethane castors. They are frequently made use of interchangeably, despite their unique features and they are common on around 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 key criteria of caster selection is pinpointing the maximum load. Polyurethane castors can usually carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have quite thin threads compared to rubber casters, which boosts their load capacity. Polyurethane castors will also be extra resistant to splitting and tearing.

Ground Protection & Marking


Regular Rubber Castors are made using 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 very important.

Polyurethane Conversely doesn't commonly mark flooring.

Even get more info though Polyurethane is generally combined by 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 easier it truly is to maneuver the products. This increases operator check here ease and comfort and effectiveness. With regards to lowering roll resistance, two points check here make any difference – 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 constant texture provides constant levels of rolling friction, leading to lowered roll resistance.

Toughness


Rubber castors give 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 significantly higher resistance to wear and abrasion. Polyurethane castor wheels can survive as much as three times longer than rubber castor wheels under controlled testing. With regards to the composition, polyurethane castors also are likely to outperform rubber castors with regard to oil, grease, and chemical resistance.

As it is possible to see, deciding upon polyurethane castors will likely be the only option. It is possible to buy polyurethane castors with the AUT Web site.
