The tread of the synthetic wheel is made of impact-resistant thermoplastic rubber elastomer with a hardness of 85° shore A. Heavy duty castors & wheels with super-elastic rubber wheels are particularly suitable for high loads. So-called heavy duty twin wheel castors are used for extremely high load capacities. Cast iron castors and wheels are made of grey cast iron or ductile cast iron for very heavy load capacities. Cast iron wheels have wear resistance and are resistant to oil.
