The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are frequently made use of interchangeably, in spite of their unique features and they 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/maximum weight
Perhaps considered one of the most important criteria of caster selection is determining the most load. Polyurethane castors can typically carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors may have pretty skinny threads compared to rubber casters, which boosts their load capacity. Polyurethane castors will also be more immune to splitting and tearing.
Ground Protection & Marking
Normal 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 appropriate for applications where floor marking Attributes are crucial.
Polyurethane Alternatively won't generally mark flooring.
While Polyurethane is mostly blended with 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 aspect for ease of use. The less the roll resistance, the less difficult it is actually to move the gear. This will increase operator consolation and efficiency. In relation to lessening roll resistance, two issues make a difference – consistency and hardness of the material.
Polyurethane castors are more standard in character than normal rubber thanks to their artificial composition. The material’s highly consistent texture offers steady levels of rolling friction, leading to minimized roll resistance.
Longevity
Rubber castors present you with a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane castor wheels have considerably greater resistance to wear and abrasion. Polyurethane castor wheels can survive as much as three view more times longer than rubber castor wheels under controlled testing. 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, picking out polyurethane castors is frequently the only option. You'll be able to buy polyurethane castors with the AUT Web site.
