What is the difference between rubber caster wheel and polyurethane caster wheel?


rubber caster wheel and polyurethane caster wheel

What is the difference between rubber caster wheel and polyurethane caster wheel? There are four major differences


1. Rolling resistance
The chemical composition of the polyurethane material determines that it has a lower rolling resistance than rubber.


2. Buffer capacity
The cushioning capacity of the caster is directly related to the hardness of the caster. The higher the hardness, the harder the caster, the worse the impact absorption capacity, the worse the cushioning capacity. The rubber hardness is usually 65-75 degrees, and the polyurethane hardness is 83-95 degrees Because of the high hardness of polyurethane casters, the cushioning capacity is poor.


3. Carrying capacity
The load-bearing capacity of the polyurethane caster is about twice that of the rubber caster. The polyurethane caster has excellent resistance to crack growth, tear resistance, and chipping resistance. The rubber wheels often suffer from such problems and are damaged early.


4. Wear resistance
Rubber casters are soft and comfortable, but they are not as wear-resistant as polyurethane casters. In general, the wear resistance of polyurethane caster wheel is 4 times that of rubber caster wheel.
