The preferred option in the material handling sector are rubber and polyurethane castors. They are regularly utilized interchangeably, regardless of their distinctive functions and are commonplace on about eighty% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which should you think about using?
Load capacity/highest weight
Most likely among The key issues of caster selection is pinpointing the maximum load. Polyurethane castors can usually carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors can have incredibly thin threads in comparison to rubber casters, which boosts their load capacity. Polyurethane castors also are much 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, especially wood & tiled flooring and is thus not ideal for applications where by floor marking properties are crucial.
Polyurethane Alternatively won't usually mark flooring.
Although Polyurethane is normally mixed 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 lower the roll resistance, the simpler it can be to maneuver the equipment. This will increase operator comfort and ease and efficiency. In relation to lessening roll resistance, two items make a difference – consistency and hardness of the material.
Polyurethane castors tend to be more standard in nature than natural rubber as a result of their artificial composition. The material’s remarkably constant texture provides constant levels of rolling friction, leading to minimized roll resistance.
Longevity
Rubber castors offer a softer ride, However they don’t last as long as polyurethane castors. Rubber castor wheels drop tread with time, While polyurethane castor wheels get more info have drastically better resistance to wear and abrasion. Polyurethane castor wheels can endure nearly 3 times longer than rubber castor wheels under managed tests. Depending on the composition, polyurethane castors also have a check here tendency to outperform rubber castors with regards to oil, grease, and chemical resistance.
As you check here are able to see, deciding on polyurethane castors is often your best option. You'll be able to buy polyurethane castors through the AUT Web site.
