Polyurethane Castors V Rubber Castors

The most well-liked option in the material handling sector are rubber and polyurethane castors. They are routinely utilized interchangeably, in spite of their distinctive features and therefore are widespread on close to eighty% of industrial applications.

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

Load capability/highest weight

Perhaps among the most important issues of caster choice is analyzing the most load. Polyurethane castors can ordinarily carry heavier weights than rubber casters as a result of the hardness of the material. Also, polyurethane castors might have pretty slim threads in comparison to rubber casters, which raises their load capacity. Polyurethane castors can also be much more resistant to splitting and tearing.

Ground Protection & Marking

Conventional Rubber Castors are created applying Carbon Black Filler. Sad to say, this Carbon Black will mark flooring, notably wooden & tiled floors and it is for that reason not suited to applications wherever floor marking Attributes are very important.

Polyurethane Then again will not usually mark flooring.

Whilst Polyurethane is normally combined with 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 feature for simplicity of use. The lower the roll resistance, the less complicated it can be to move the products. This will increase operator comfort and performance. In relation to decreasing roll resistance, two matters make a difference – consistency and hardness of the material.

Polyurethane castors tend to be more uniform in character than normal rubber because of their artificial composition. The material’s highly constant texture check here provides regular amounts of rolling friction, leading to lessened roll resistance.

Sturdiness

Rubber castors give a softer ride, Nevertheless they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, While polyurethane castor wheels have noticeably greater resistance to wear and abrasion. Polyurethane castor wheels can endure nearly three times longer than rubber castor wheels under controlled tests. Based on the composition, polyurethane castors also are likely to outperform rubber castors when it comes to oil, grease, and chemical resistance.

As you'll be able to see, deciding upon polyurethane castors is generally your best option. You'll be able to get polyurethane castors from the AUT website.
