Difference between nylon caster and polyurethane caster
Nylon caster have high hardness,loud sound,but slightly thrust required.
Polyurethane caster have less hardness, low operation sounds,but need ore force to push heavy objects
General speaking nylon caster have high hardness,more wear resistance,and can load much heavy objects,
Polyurethane are softer,better in noise reduce, intensity relatively badly
Of course there have soft nylon,and hardness polyurethane
Nylon wheel wear of the floor will be bigger, when turning the noise is large, polyurethane seismic capacity is good,for the material in all the wheels, the wheels of polyurethane are best performance in all aspects!
