Polyurethane Castors Versus Rubber Castors

The most popular option in the material handling sector are rubber and polyurethane castors. They're usually employed interchangeably, no matter their distinctive functions and are commonplace on about eighty% of industrial applications.

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

Load capacity/highest weight

Perhaps considered one of the most important criteria of caster choice 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 immune to splitting and tearing.

Ground Protection & Marking

Normal Rubber Castors are created making use of Carbon Black Filler. Sad to say, this Carbon Black will mark floors, notably wood & tiled floors and it is hence not appropriate for applications where by floor marking properties are crucial.

Polyurethane However isn't going to frequently mark flooring.

Whilst Polyurethane is mostly blended by using a colourant, the chemical make-up of the material locks the colour into the material read more 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 convenience and performance. With regards to minimizing roll resistance, two matters make any difference – consistency and hardness of the material.

Polyurethane castors tend to be more uniform in nature than pure 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, Nonetheless 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 times longer than rubber castor wheels under controlled testing. 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 order polyurethane castors from the AUT Web-site.
