What are rubber casters, what is the difference between rubber casters and polyurethane casters, Ningbo Shangxin brand casters will introduce the differences of different casters for you.
1. Rolling resistance
The chemical makeup of the polyurethane material determines that it has 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, and the worse the cushioning capacity. The hardness of rubber is usually 65-75 degrees Shore A, while the hardness of polyurethane is 83-95 degrees. , because polyurethane casters have higher hardness, so the cushioning capacity is poor.
3. Carrying capacity
The load-bearing capacity of polyurethane casters is about twice that of rubber casters. Polyurethane casters have excellent resistance to crack growth, tearing, and chipping, while rubber wheels often suffer from such problems and are damaged early.
4. Wear resistance
Rubber casters are soft and have good comfort performance, but they are not as wear-resistant as polyurethane casters. Generally speaking, the wear resistance of polyurethane casters is 4 times that of rubber casters.
