The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are often used interchangeably, despite their unique attributes and 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 generally carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors can have incredibly thin threads compared to rubber casters, which will increase their load ability. Polyurethane castors may also be more resistant to splitting and tearing.
Ground Protection & Marking
Regular Rubber Castors are made utilizing Carbon Black Filler. Sad to say, this Carbon Black will mark floors, specifically wood & tiled floors and is thus not ideal for applications wherever ground marking properties are very important.
Polyurethane on the other hand will not commonly mark flooring.
Whilst Polyurethane is usually combined 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 an important attribute for simplicity 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 reducing roll resistance, two items 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 lessened roll resistance.
Durability
Rubber castors offer a softer ride, However they don’t last as long as polyurethane castors. get more info Rubber castor wheels drop tread with time, While polyurethane castor wheels have substantially increased resistance to wear and abrasion. Polyurethane castor wheels can survive approximately three times longer than rubber castor wheels under controlled screening. With regards to the composition, polyurethane castors also are likely to outperform rubber castors with regard to oil, grease, and chemical resistance.
As it is possible to see, picking out polyurethane castors will likely be the only option. You'll be able to buy polyurethane castors with the AUT Web site.
