The most popular option in the material handling sector are rubber and polyurethane castors. They're usually employed interchangeably, no matter their distinctive characteristics and therefore are prevalent on close to 80% of industrial applications.
But, what’s the difference between rubber and polyurethane castors and which must you consider using?
Load capability/maximum weight
Perhaps considered one of the most important considerations of caster choice is figuring out the most load. Polyurethane castors can normally carry heavier weights than rubber casters because of the hardness of the material. Also, polyurethane castors may have extremely slim threads when compared with rubber casters, which raises their load ability. Polyurethane castors may also be extra resistant to splitting and tearing.
Ground Protection & Marking
Normal Rubber Castors are created making use of Carbon Black Filler. Unfortunately, this Carbon Black will mark floors, significantly wooden & tiled flooring and is for that reason not suitable for applications wherever ground marking properties are very important.
Polyurethane on the other hand isn't going view more to frequently mark flooring.
While Polyurethane is mostly blended with a colourant, the chemical make-up of the material locks the colour into the material and can't view more leach or mark flooring surfaces.
Roll Resistance
Roll resistance is a crucial function for ease of use. The smaller the roll resistance, the easier it truly is to maneuver the products. This raises operator convenience and performance. With regards to minimizing roll resistance, two matters matter – consistency and hardness of the material.
Polyurethane castors are more uniform in character than purely natural rubber because of their synthetic composition. The material’s very constant texture delivers consistent levels of rolling friction, resulting in lowered roll resistance.
Toughness
Rubber castors give a softer experience, Nonetheless they don’t last as long as polyurethane castors. Rubber castor wheels shed tread with time, whereas polyurethane castor wheels have substantially larger resistance to wear and abrasion. Polyurethane castor wheels can endure approximately 3 times longer than rubber castor wheels under managed screening. Depending upon here the composition, polyurethane castors also usually outperform rubber castors in terms of oil, grease, and chemical resistance.
As you can see, choosing polyurethane castors is normally your best option. You are able to purchase polyurethane castors from the AUT website.
