The main frame of the caster is made of steel, and the wheel core is made of polypropylene (PP) with strong bearing capacity.
TPR is used as the wheel surface material, which has excellent oil resistance, water resistance, drug resistance and mold resistance, and also has good shock absorption and noise reduction.
The outside of the wheel is made of ABS material, which is anti-corrosion and wear-resistant. The combination of the universal rotating ball disc and the balls has high load and strong bearing capacity.
