The most well-liked choice in the material handling sector are rubber and polyurethane castors. They are often utilized interchangeably, regardless of their distinctive functions and are commonplace 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
Probably among The key issues of caster selection is pinpointing the maximum load. Polyurethane castors can usually carry heavier weights than rubber casters due to the hardness of the material. Also, polyurethane castors can have incredibly thin threads as compared to rubber casters, which will increase their load capacity. Polyurethane castors will also be more resistant to splitting and tearing.
Ground Protection & Marking
Normal Rubber Castors are created making use of Carbon Black Filler. Regretably, this Carbon Black will mark floors, significantly wooden & tiled flooring and it is consequently not well suited for applications exactly where flooring marking Attributes are important.
Polyurethane On the flip side does not normally mark flooring.
Even though Polyurethane is generally combined by using 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 an important element for simplicity of use. The lower the roll resistance, the simpler it can be to maneuver the equipment. This will increase operator consolation and efficiency. In relation to lessening roll resistance, two issues make a difference – consistency and hardness of the material.
Polyurethane castors tend to be more standard in character than purely natural rubber due to their synthetic composition. The material’s hugely constant texture delivers consistent levels of rolling friction, resulting in lowered roll resistance.
Sturdiness
Rubber castors give a softer journey, Nonetheless they don’t here last as long as polyurethane castors. Rubber castor wheels reduce tread with time, whereas polyurethane castor wheels have considerably greater resistance to wear and abrasion. Polyurethane castor wheels can survive around three times longer than rubber castor wheels under controlled testing. With regards to the composition, polyurethane castors also are likely to outperform rubber view more 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.
