Polyurethane Castors Compared with Rubber Castors

The most popular option in the material handling sector are rubber and polyurethane castors. They're usually employed interchangeably, regardless of their distinctive functions and are commonplace on around eighty% of industrial applications.

But, what’s the difference between rubber and polyurethane castors and which must you think about using?

Load capacity/highest 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 boosts their load capacity. Polyurethane castors will also be more resistant to splitting and tearing.

Ground Protection & Marking

Normal Rubber Castors are created utilizing Carbon Black Filler. Sad to say, this Carbon Black will mark floors, specifically wood & tiled floors and is hence not appropriate for applications where by floor marking properties are very important.

Polyurethane However isn't going to frequently mark flooring.

While Polyurethane is mostly blended with a colourant, the chemical make-up of the click here material locks the colour into the material and cannot leach or mark flooring surfaces.

Roll Resistance

Roll resistance is a vital element for simplicity of use. The lower the roll resistance, the simpler it can be to maneuver the equipment. This raises operator more info convenience and performance. With regards to lowering roll resistance, two points make any difference – consistency and hardness of the material.

Polyurethane castors are more uniform in nature than normal rubber on account of their artificial composition. The material’s really constant texture provides constant levels of rolling friction, leading to lowered roll resistance.

Toughness

Rubber castors give a softer experience, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels reduce tread with time, Whilst polyurethane castor wheels have significantly higher resistance to wear and abrasion. Polyurethane castor wheels can survive up to three times longer than rubber castor wheels under managed tests. Based on the composition, polyurethane castors also often outperform rubber castors with regards to oil, grease, and chemical resistance.

As you are able to see, picking polyurethane castors is normally your best option. You are able to purchase polyurethane castors from the AUT website.
