The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are often used interchangeably, despite their unique attributes and are widespread on around eighty% of industrial applications.
But, what’s the difference between rubber and polyurethane castors and which must you consider using?
Load capability/highest weight
Perhaps considered one of the most important criteria of caster choice is determining the most 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 compared to rubber casters, which increases their load capability. Polyurethane castors are also a lot more immune to splitting and tearing.
Floor Protection & Marking
Typical Rubber Castors are manufactured working with Carbon Black Filler. Sadly, this Carbon Black will mark flooring, particularly wooden & tiled flooring and it is as a result not well suited for applications exactly where ground marking Attributes are essential.
Polyurethane On the flip side doesn't normally 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 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 standard in nature than all-natural rubber on account of their artificial composition. The material’s remarkably constant texture provides consistent levels of rolling friction, resulting in lowered roll resistance.
Toughness
Rubber castors give a softer journey, 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 up to three times longer than rubber castor wheels under controlled testing. Based on the composition, polyurethane castors also often outperform rubber castors with regards to oil, grease, more info and chemical resistance.
As you are able to see, deciding on polyurethane castors is often your best option. You are able to purchase polyurethane castors from the AUT website.
