Polyurethane Castors Compared with Rubber Castors
The most popular choice in the material handling sector are rubber and polyurethane castors. They're routinely used interchangeably, irrespective of their unique functions and so 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 among the most important factors 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 might have incredibly skinny threads when compared to rubber casters, which will increase their load capacity. Polyurethane castors are also extra immune to splitting and tearing.
Floor Protection & Marking
Standard Rubber Castors are created working with Carbon Black Filler. Regrettably, this Carbon Black will mark floors, significantly wooden & tiled floors and it is as a result not ideal for applications where flooring marking properties are crucial.
Polyurethane Alternatively doesn't commonly mark flooring.
While Polyurethane is normally combined 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 attribute for ease of use. The less the roll resistance, the easier it truly is to maneuver the gear. This improves operator convenience and performance. In regards to decreasing roll resistance, two matters matter – consistency and hardness of the material.
Polyurethane castors tend to be more uniform in nature than pure rubber due to their artificial composition. The material’s really consistent texture supplies consistent levels of rolling friction, leading to lessened roll resistance.
Sturdiness
Rubber castors give you a softer experience, but they don’t last as long as polyurethane castors. Rubber castor wheels drop tread with time, Whilst polyurethane castor wheels have significantly larger resistance to wear and abrasion. Polyurethane castor wheels can endure as many as 3 times longer than rubber castor wheels under controlled testing. Depending upon the composition, polyurethane castors also have a tendency to outperform rubber castors regarding oil, grease, and chemical resistance.
As it is possible to click here see, selecting polyurethane castors is generally your best option. You'll be able to buy polyurethane castors with the AUT Web-site.
