The most well-liked option in the material handling sector are rubber and polyurethane castors. They're regularly utilised interchangeably, despite 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 should you consider using?
Load capacity/maximum weight
Potentially amongst The key considerations of caster choice is pinpointing the most load. Polyurethane castors can ordinarily carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors may have really thin threads when compared with rubber casters, which will increase their load capacity. Polyurethane castors are also extra immune to splitting and tearing.
Floor Protection & Marking
Standard Rubber Castors are created employing Carbon Black Filler. Regrettably, this Carbon Black will mark floors, specially wooden & tiled flooring and it is consequently not suitable for applications where by floor marking Attributes are essential.
Polyurethane However would not normally mark flooring.
Whilst Polyurethane is mostly mixed by 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 crucial function for simplicity of use. The lower the roll resistance, the less complicated it really is to maneuver the equipment. This boosts operator ease and comfort and performance. In relation to reducing roll resistance, two points matter – consistency and hardness of the material.
Polyurethane castors tend to be more standard in character than purely natural rubber due to their synthetic composition. The material’s very consistent texture supplies reliable amounts of rolling friction, causing minimized roll resistance.
Longevity
Rubber castors present you with a softer ride, but they don’t last as long as polyurethane castors. Rubber castor wheels lose tread click here 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 tests. According to the composition, polyurethane castors also are inclined to 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 order polyurethane castors from the AUT Web-site.
