The preferred option in the material handling sector are rubber and polyurethane castors. They're regularly employed interchangeably, regardless of their distinctive characteristics and are prevalent on close to 80% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which must you consider using?
Load capability/maximum weight
Most likely one among The key things to consider 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
Common Rubber Castors are created making use of Carbon Black Filler. Regretably, this Carbon Black will mark floors, specially wooden & tiled floors and it is therefore not suited to applications where flooring marking Attributes are important.
Polyurethane Alternatively would get more info not usually mark flooring.
Although Polyurethane is normally mixed with 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 a crucial feature for ease of use. The less the roll resistance, the less complicated it is to move the gear. This boosts operator consolation and efficiency. In regards to lessening roll resistance, two issues make a difference – 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 reduced roll resistance.
Durability
Rubber castors provide a softer trip, However they don’t last as long as polyurethane castors. Rubber castor wheels drop tread with time, While polyurethane castor wheels have drastically increased resistance to wear and abrasion. Polyurethane castor wheels can endure as many as 3 times longer than rubber castor wheels under managed screening. Dependant upon the composition, polyurethane castors also usually outperform rubber castors concerning oil, grease, and chemical resistance.
As it is possible to see, deciding upon polyurethane castors is usually the only option. It is possible to buy polyurethane castors with the AUT Web site.
