The most well-liked option in the material handling sector are rubber and polyurethane castors. They're frequently employed interchangeably, in spite of their distinctive capabilities and are commonplace on close to eighty% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which must you consider using?
Load capacity/maximum weight
Perhaps one of the most important factors of caster selection is identifying the maximum load. Polyurethane castors can typically carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors can have pretty slim threads compared to rubber casters, which improves their load ability. Polyurethane castors will also be a lot more resistant to splitting and tearing.
Ground Protection & Marking
Common Rubber Castors are produced utilizing Carbon Black Filler. Unfortunately, this Carbon Black will mark flooring, notably wooden & tiled flooring and is consequently not suitable for applications where by flooring marking properties are very important.
Polyurethane Alternatively does not frequently mark flooring.
While Polyurethane is generally combined 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 an important element read more for ease of use. The smaller the roll resistance, the simpler it is actually to move the products. This will increase operator comfort and effectiveness. In terms of lessening roll resistance, two factors make any difference – consistency and hardness of the material.
Polyurethane castors are more standard in nature than normal rubber thanks to their synthetic composition. The material’s click here remarkably consistent texture gives dependable levels of rolling friction, leading to lessened roll resistance.
Durability
Rubber castors give a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels get rid of tread with time, Whilst polyurethane castor wheels have considerably increased resistance to wear and abrasion. Polyurethane castor wheels can endure up to three times longer than rubber castor wheels under controlled screening. Based on the composition, polyurethane castors also are inclined to outperform rubber castors concerning oil, grease, and chemical resistance.
As you can see, picking polyurethane castors is frequently the only option. You can order polyurethane castors from the AUT website.
