Polyurethane Castors Vs Rubber Castors
The most well-liked choice in the material handling sector are rubber and polyurethane castors. They're commonly utilised interchangeably, no matter their distinctive characteristics and therefore are commonplace on about eighty% of industrial applications.
But, what’s the difference between rubber and polyurethane castors and which must you consider using?
Load capability/maximum weight
Potentially one among The key things to consider of caster selection is analyzing the maximum load. Polyurethane castors can ordinarily carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors might have extremely slim threads when compared with rubber casters, which increases their load capability. Polyurethane castors are much more immune to splitting and tearing.
Floor Protection & Marking
Normal Rubber Castors are created making use of Carbon Black Filler. Sad to say, this Carbon Black will mark floors, specifically wood & tiled floors 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 with a colourant, the chemical make-up of the material locks the colour into the material and cannot leach or mark flooring surfaces.
Roll Resistance
Roll resistance is a crucial aspect for ease of use. The lower the roll resistance, the less difficult it can be to maneuver the equipment. This raises operator convenience and performance. With regards to lowering roll resistance, two points make any difference – consistency and hardness of the material.
Polyurethane castors are more uniform in nature than all-natural rubber as a result of their artificial composition. The material’s hugely constant texture delivers dependable amounts of rolling friction, causing reduced roll resistance.
Durability
Rubber castors provide a softer trip, However they don’t last as long as polyurethane castors. Rubber castor wheels drop tread with time, While polyurethane castor wheels have substantially larger resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under controlled testing. here Dependant upon the composition, polyurethane castors also usually outperform rubber castors concerning oil, grease, and chemical resistance.
As it is possible to see, deciding upon polyurethane castors will likely be the only option. You'll be able to buy polyurethane castors through the AUT website.
