Polyurethane Castors Compared to Rubber Castors

The most popular option in the material handling sector are rubber and polyurethane castors. They are commonly used interchangeably, irrespective of their distinctive capabilities and are prevalent on around 80% of industrial applications.

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

Load capability/highest weight

Potentially amongst The key considerations 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 can have very slim threads in comparison to rubber casters, which increases their load ability. Polyurethane castors also are a lot more resistant to splitting and tearing.

Ground Protection & Marking

Typical Rubber Castors are produced making use of Carbon Black Filler. Unfortunately, this Carbon Black will mark flooring, notably wooden & tiled flooring and is hence not suited to applications exactly where ground marking properties are crucial.

Polyurethane Then again doesn't commonly mark flooring.

While Polyurethane is mostly mixed 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 an important attribute for simplicity of use. The smaller the roll resistance, the simpler it can be to maneuver the equipment. This will increase operator consolation and efficiency. On the subject of decreasing roll resistance, two items make a difference – consistency and hardness of the material.

Polyurethane castors tend to be more standard in character than natural rubber as a result of their synthetic composition. polyurethane castors The material’s very consistent texture supplies reliable amounts of rolling friction, causing lessened 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, Whilst polyurethane castor wheels have noticeably bigger resistance to wear and abrasion. Polyurethane castor wheels can endure approximately three times longer than rubber castor wheels under controlled testing. Based on the composition, polyurethane castors also polyurethane castors often outperform rubber castors with regards to oil, grease, and chemical resistance.

As you are able to see, selecting polyurethane castors will likely be your best option. You are able to get polyurethane castors with the AUT website.
