What is rubber castor, what is the difference between rubber castor and polyurethane castor, just introduce the different points of different castor for you.

1. Rolling resistance

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

2. Buffer capacity

The cushioning capacity of castor is directly related to the hardness of castor, the higher the hardness, the harder the castor, the worse the impact absorption capacity, the worse the cushioning capacity, the rubber hardness Shore A is usually in 65-75 degrees, and the polyurethane hardness in 83-95 degrees, because the polyurethane castor hardness is higher, so the cushioning capacity is poor.

3. Carrying capacity

The bearing capacity of polyurethane casters is about 2 times that of rubber casters. Polyurethane casters have superior anti-crack growth, anti-tear and anti-collapse properties, while rubber wheels often suffer from such problems and early damage.

4. Wear resistance

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

Huizhou Jianli Hardware Casters Co., Ltd is a professional manufacturer of industrial casters, which has developed and produced more than 5000 casters of different specifications. Since the establishment of the factory for many years, the company has been flattering the customer-oriented and quality-oriented professional spirit, developing casters of different models and specifications for customers.
