Conductive rubber tread materials offer excellent electrical discharging throughout the tread and across the whole contact surface. The steel bracket is Zinc coating so the whole caster is electrical conductive. The caster will then producing a continuous and safe discharging to ensure the safety of electronic devices.

These high quality cast iron wheels can withstand high temperatures and exposure to water or the environment. They will rust over time. Cast iron wheels can also withstand exposure to chemicals, grease and oils.

The payloads are often subjected to damaging shock forces as the vehicles' running gear comes in contact with surface obstructions. As a result, shock caused by impact becomes a significant limiting factor to overcome.
