The most well-liked choice in the material handling sector are rubber and polyurethane castors. They're routinely utilised interchangeably, irrespective of their distinct capabilities and so are prevalent on about 80% of industrial applications.
But, what’s the distinction between rubber and polyurethane castors and which should you think about using?
Load capacity/highest weight
Possibly amongst The main considerations of caster choice is figuring out 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 will increase their load ability. Polyurethane castors may also be extra resistant to splitting and tearing.
Ground Protection & Marking
Regular Rubber Castors are made using Carbon Black Filler. However, this Carbon Black will mark flooring, especially wood & tiled flooring and is for that reason not suitable for applications exactly where ground marking Attributes are essential.
Polyurethane On the flip side does not typically mark flooring.
Although Polyurethane is normally 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 a crucial feature for ease of use. The less the roll resistance, the less complicated it is to move the gear. This will increase operator consolation and efficiency. In terms of minimizing roll resistance, two matters matter – 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 consistent levels of rolling friction, resulting in reduced roll resistance.
Durability
Rubber castors offer a softer ride, but they don’t last as long as polyurethane castors. Rubber castor wheels lose tread with time, whereas polyurethane castor wheels have significantly bigger resistance to wear and abrasion. more info Polyurethane castor wheels can endure around three times longer than rubber castor wheels under managed tests. Dependant upon the composition, polyurethane castors also are likely to outperform rubber castors regarding oil, grease, and chemical resistance.
As you are able to see, deciding upon polyurethane castors is normally the only option. You are able to get polyurethane castors from the AUT Web site.
