Polyurethane Castors Compared to Rubber Castors

The preferred choice in the material handling sector are rubber and polyurethane castors. They are commonly used interchangeably, irrespective of their unique characteristics and so are widespread on about eighty% of industrial applications.

But, what’s the distinction between rubber and polyurethane castors and which should you consider using?

Load capacity/maximum weight

Possibly one of the most important factors of caster selection is figuring out the maximum load. Polyurethane castors can generally carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors might 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

Typical Rubber Castors are made making use of Carbon Black Filler. Sadly, this Carbon Black will mark flooring, specially wooden & tiled floors and it is as a result not ideal for applications where flooring marking properties are crucial.

Polyurethane Then again will not generally mark flooring.

Although Polyurethane is usually blended 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 a vital feature for simplicity of use. The lower the roll resistance, the less complicated it really is to maneuver the gear. This improves operator convenience and performance. In regards to lowering roll resistance, two matters make a difference – consistency and hardness of the material.

Polyurethane castors tend to be more uniform in character than natural rubber on account of their artificial composition. The material’s very constant texture offers regular amounts of rolling friction, resulting in minimized roll resistance.

Durability

Rubber castors give you a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels get rid of tread read more 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 tests. Based on the composition, polyurethane castors also are inclined to outperform rubber castors in terms of oil, grease, and chemical resistance.

As you are able to see, deciding on polyurethane castors click here is frequently the only option. You can purchase polyurethane castors through the AUT Web site.
