The most well-liked 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 capacity/highest weight
Perhaps considered one of The main considerations of caster choice is figuring out the most load. Polyurethane castors can normally carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors may have extremely skinny threads when compared with rubber casters, which increases their load capability. Polyurethane castors can also be far more resistant to splitting and tearing.
Flooring Protection & Marking
Standard Rubber Castors are made using Carbon Black Filler. However, this Carbon Black will mark flooring, specifically wood & tiled floors and is hence not appropriate for applications where by floor marking properties are crucial.
Polyurethane However isn't going to generally mark flooring.
While Polyurethane is mostly blended with a colourant, the chemical make-up of learn more the material locks the colour into the material and can't leach or mark flooring surfaces.
Roll Resistance
Roll resistance is a crucial feature for ease of use. The less the roll resistance, the less complicated it is to move the tools. This improves operator comfort and effectiveness. On the subject of 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 really constant texture provides constant levels of rolling friction, leading to diminished roll resistance.
Toughness
Rubber castors present you with a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels eliminate 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. According to the composition, polyurethane castors check here also are inclined 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 get polyurethane castors with the AUT Web site.
