The most well-liked option in the material handling sector are rubber and polyurethane castors. They're regularly made use of interchangeably, regardless of their distinct attributes and therefore are common 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
Probably one among The main things to consider of caster choice is deciding the maximum load. Polyurethane castors can typically carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have very slim threads compared 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 utilizing Carbon Black Filler. Unfortunately, this Carbon Black will mark flooring, notably wooden & tiled flooring and is consequently not suitable for applications where by flooring marking Attributes are very important.
Polyurethane Alternatively does not commonly mark flooring.
While Polyurethane is more info 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 element for ease of use. The smaller the roll resistance, the simpler it is actually to move the products. This raises operator consolation and effectiveness. With regards to lessening roll resistance, two items make any difference – consistency and hardness of the material.
Polyurethane castors are more standard in nature than normal rubber because of their synthetic composition. The material’s remarkably consistent texture supplies consistent levels of rolling friction, leading to lessened roll resistance.
Sturdiness
Rubber castors give a softer ride, However they don’t last as long as polyurethane castors. Rubber castor wheels eliminate tread with time, whereas polyurethane castor wheels have substantially better resistance to wear and abrasion. Polyurethane castor wheels can endure as much as three times longer than rubber castor wheels under managed tests. According to the composition, polyurethane castors also read more are likely to outperform rubber castors in terms of oil, grease, and chemical resistance.
As you are able to see, deciding on polyurethane castors will likely be the best choice. You can purchase polyurethane castors through the AUT Web site.
